Have you ever heard about “Radon” gas ?
All of you know about the Radium that was discovered by Pierre and Marie Curie, but only a few may know what is the radon.
The radon is a radioactive gas of natural origin. It has no smell and no colour. You can find it anywhere on the planet. It is a product of the disintegration of radium, itself a product of the uranium that can be found anywhere in the soil. Concentration of radon in the air depends on the type of soils. With granite or volcanic soils the production of radon is usually higher.
Radon can be used in medical radiotherapy . At the same time it was confirmed by the World Health Organization that it
can provoke cancers.
In France measures of radon gas levels are undertaken regularly on the whole territory by the National institute of nuclear safety, based on the principle that you can find Uranium almost anywhere in the soils.
While it is important to understand better the impact of Radon gas on public health and particularly cancer incidence, it cannot be compared with other major factors such as for example tobacco consumption, or urban pollution.
To prevent risks there should be a good ventilation of the room, and a covering of the soil.

Nuclear Energy
The civil nuclear energy has reach it highest production just after the oil crisis, but since several accidents such as Three Miles Island in 1979 and Tchernobyl in 1986, this development slowed down.
But this production isn’t starting again Nowaday?
Maybe we can suppose that:
- The augmentation of oil price (150 $ the barrel in 2008)
- The anticipation of oil shortage
- The climate changement
Are reasons of this new tendancy
The governement has found 2 solutions; The renewable energy and the nuclear energy.
Unfortunatly, the first solution could have limits and we all that nuclear energy is not the miracle solution. Indeed it we can indentify different problems: for instance:
- The irradiation worker, neighbour population.
- Radioactif material
- The nuclear wast management
- The nuclear weapon proliferation
In a few years time, it would be necessary to create an international organisation able to control nuclear energy production with the intention of reducing climate problems at the moment.

Radioactivity and human activity
The radiations alpha and beta are particles but the radiations gamma are electromagnetic waves. A paper can stop a radiation alpha, a plate of alumunim for a radiation beta, while a thick concrete wall, a plate of cast iron or gold is necessary for stop one radiation gamma.
The radiations affect the bodies by way external or internal.
A large part of the radioactivity is natural (for example in France, the natural radioactivity is 1.64 millisieverts a year).
But there is also an artificial radioactivity:
In France, the exposure comes mainly from the medical irradiation with 0.8 millisievert, only 0,06 millisievert a year results from fallout from the tries of nuclear weapons and from the leaks of the atomic energy.
But it is not the case everywhere...
The ITER project
These new reactors shall use the principle of the nuclear fusion, and not the fission, as make it current reactors.
Advantages:
-iter will not emit of greenhouse gases - iter will not generate radioactive waste persistent element radioactive the period of which is lower or 30-year-old equal (the period of the tritium is 12,3-year-old equal)
- abundance of reagent necessities
- Possibility of covering all the needs in energy of the planet
Inconveniences:
-the nuclear fusion is maybe only a dream - project enormously costly (10 billion euro) which is not on to make a success. This money could serve for developer the renewable and useful energies of today.
-Concern the long term (not before 2050)

Nuclear technology and food preservation and water
While there is strong resistance in the public on the use of nuclear radiation technique for food sanitation and preservation, the technique is apparently used more and more often.......

nuclear anecdotes
A portrait of Staline highly radioactive. The Figaro of 29 November 1993 would have reported that a portrait of Staline engraved on a plate of radium was removed from the museum where it was exposed and burried in a nuclear waste deposit in view of the high level of radiations it was producing.
Alcoholic drinks prohibited in french nuclear plants. Since 1993, alcoholic beverages have been prohibited in french nuclear plants following an accident in Palluel nuclear plant where an employee had stopped the functioning of 3 reactors because he was upset. During the investigation the technician said that he was in fact under influence of alcohol ( let us say that he was drunk !) following a little party in the plant with is colleagues.
Drink Vodka to protect yourself against radiations. On the label of the botle of russian Vodka ROSSIYSKAYA KORONA it is mentioned that it is a product ecologically pure, and that can prevent and protect against cancers, radioactivity and gastroenteritis.....! This would confirm why apparently the "liquidators" in Chernobyl were provided with good rations of Vodka. This makes sense: knowing that once you have been contaminated there is very little things you can do to stop the evolving of cancer, then with a good dose of Vodka you can observe patiently and with serenity the progression of your illness...These special properties of acoholic drinks are known since long: During first world war, french soldiers were advised to drink wine to protect themselves from ennemies' bullets.

Nuclear stories and cinema
The stories can be classified in two groups:
Group 1: Movies in which the heroes have to prevent a nuclear catastrophe provoked by bad terrorists or before the end of the cold war by bad Russian generals hiding behind the iron curtain and fighting good Americans generals. The nuclear bomb can be transported by a plane, a submarine or even a train. Usually the good guys succeed in stopping the bad ones at the last minute and the world is saved from the nuclear war.
It is interesting to note that in the past there were more movies from group 1 ( the nuclear war has been avoided) and that most recent popular movies are more from group 2 ( the nuclear war already took place). Let us hope that it is not because the public and movie directors got used to the idea that the nuclear war should happen one day or another....

Nuclear news. Enjoy modern life
This week the Agency France Press (AFP) is giving us two important nuclear news: A bad one and a good one
Lets us start by the bad one: China - A ball of Caesium 137 lost in nature.
According to the New China news agency a scale used for industrial purpose would have disappeared from a factory in Sanxchi province. You may think that there is nothing too serious so far..... The problem is that this instrument contained a metallic ball with a substantial quantity of Caesium 137, a radioactive material that can explode if in contact with water. An intensive search has been ordered by the local authorities. There is hope that the Caesium may be found in the 5000 tons of waste material produced by the factory. The latest good news is that some abnormal level of radioactivity was measured in a neighbouring factory which purchased some scrap iron from the place where the Caesium was lost.... The latest bad news is that this factory is manufacturing iron and the Caesium may have already been melted..... I leave it to your imagination what could be the next reincarnation of the lost Chinese Caesium 137 ball: A car, a bicycle, a tin???
Now the good one: Sahara and Polynesia. Compensation for the victims of French nuclear tests.
Our Minister of defence: Mr Herve Morin has unveiled this week a proposal of law to compensate the victims of the 210 nuclear tests undertaken by our country from 1960 to 1966 in the Sahara and from 1966 to 1996 in Polynesia (see our previous story). A first annual compensation some 10 million Euros would be set aside to compensate the potentially 150 000 workers and the unknown number of civilians concerned who were living in the areas were the tests took place. This is good news, even though one would immediately ask the question why so late? Better late than never in any case. Minister Morin said that it was one of the first tasks he had asked his Ministry to work on when he took his job. Despite their reservations, he proceeded. He further said that for him it was a matter of consciousness. Compensation will be provided based on a list of 18 illness established by the United Nations as potentially resulting from radiations (cancer, leukaemia, etc...). A medical commission will study the requests for compensation and decide on the validity and the amount to be provided to the victims. The Ministry of defence already publicly recognized in the past 4 nuclear incidents during tests in the Sahara and 10 in Polynesia.

Do you know what the acronym IAEA stands for ?
It has also the responsibility to control the use of atomic energy in the world. It was created in 1953. The Director General Hans Blix of IAEA is coming from Egypt. He received the nobel peace prize in 2005. The agency employs more than 2300 persons in the world. Its Headquarters is in Vienna (Austria). It has a budget of approximately 225 million Euros per year.
The IAEA works on 3 activities:
1) The control of the spread of nuclear weapons;
2) The use of nuclear technology for development
3) The promotion of nuclear safety and security
The IAEA promotes and implement a system of agreements with countries to prevent the spread of nuclear weapons. The countries that signed the «global treaty on the non proliferation of nuclear weapons" accept that their civilian nuclear program be inspected by IAEA inspectors to verify that they are not used for making nuclear bombs. There are 160 countries that have signed this treaty.
The IAEA wants to ensure that nuclear technology is used only for peaceful purpose. The IAEA also promotes the use of nuclear technology in domains such as medecine, agriculture, and industry. They have some laboratories to conduct research and training activities. For agriculture for example the IAEA recommends techniques of nuclear radiations to sterilize insects (and then release the sterile males to reduce the growth of the insect population) or to modify genetically the crops.
The IAEA makes recommendations to define standards and regulations for the safety of nuclear plants. They advise also on the design and operations of these plants. They help also the countries in the world to combat the risks of nuclear terrorism and to be prepared should a nuclear accident happen somewhere.
If you want to know more about the IAEA, you can visit their web site that is full of information!

High risk shipment on its way from Cherbourg to Japan
Cergy Pontoise the 22/03/2009.
Thanks to Green Peace the public is informed that the biggest shipment of nuclear material ever transported is on its way from France to Japan. Approximately 1.8 tons of plutonium (enough to make more than 200 nuclear bombs) have left the port of Cherbourg and will be transported by sea to reach Japan in 2 months time. The shipment will probably go through territorial waters of countries that are not even aware of its existence. The transport will be under the responsibility of the British company “Pacific nuclear Transport Limited”. Two ships: the Pacific Pintail and the Pacific Heron will be escorted by military vessels and probably submarines. It is expected that in the future, there will be more and more of these shipments.The Plutonium was produced in the nuclear plant of Marcoule (Rhone valley) and stored in the plant of La Hague in Normandy. In France it was transported by trucks under military escorts.There was no public or official announcement of this news…

Where can we find Uranium ?
As we all know, to produce nuclear energy we need Uranium which will be enriched through a complex industrial process before it can be used.
Uranium can be found almost every where: in soil, in rocks, in rivers, in lakes, in oceans. Traces of uranium can be found in food, in the drinking water and also in human and animal tissues. But in most cases the Uranium is found in very very small quantities and obviously can not be extracted for industrial use at a reasonable cost.
Where are the main sources of Uranium that can be mined for industrial purpose ? The main known deposits are in Australia, Kazakhstan, United States, Canada, South Africa, Niger, Namibia, Russia, Brazil, Ukraine and Uzbekistan. The deposits with higher concentration are currently in Canada.
In France we can extract Uranium from granite but the concentration is very low (of the order of 4-5 parts per million) and huge quantities of rocks would be required. France nuclear industry relies very much on Uranium mined in Niger.
In the United States of America and Russia an important source of Uranium already enriched for the nuclear civil industry is coming from nuclear weapons that are dismantled since the 2 countries signed a disarmament treaty in 1987

The use of nuclear radiations to control insect populations
This technique has been used with great success to control the spread of the screw worm, a very bad parasite of cattle, sheep, goats but also of humans that was attacking animals in Africa (It is a type of big black fly that lays hundreds of eggs in skin wounds of the animal and then the larvaes will just come out from any part in the body, drilling the tissues and bursting through the skin... very disgusting to see the photos...). The technique is tested also for other insects including mosquitoes for the fight against malaria.

Depleted Uranium. What is it about ?
After each major war involving western military forces, the question of the use of depleted uranium munitions make the headlines of newspapers because of reported negative impact on the health of soldiers and of the population living in the areas where fighting took place. Let us review what is the story here. First of all, what is Depleted uranium (DU as they call it): It is basically a by product left from the process of enrichment of Uranium to make it usable for nuclear reactors and weapons. DU is about 40 % less radioactive than Uranium. This means that it is very little radioactive. For example, scientists say that it is 3 million less radioactive than radium that was put in old luminous alarm clocks. Why is DU used for military purpose ? It is because its extreme density makes it very good for military use to penetrate thick tank armors or in reinforcing armor protection of military vehicles. Is DU a problem for human health? There are today diverging views amongst scientists on this matter. The scientists are still debating if the DU toxicity can be responsible for poisoning soldiers and population exposed to it in large quantities, and if it poses a threat to the environment with pollution of the water. The official position of military authorities but also of the World Health Organization is that apparently there is no credible link between DU exposure and increase in human cancers or other health or environmental problems. Other scientists disagree. There are still some public health studies on going on this subject and it is too early to conclude but with the massive use of Depleted uranium ammunitions in the new conflicts this could be potentially a big problem for a large population of soldiers that have been exposed and for populations living in zones where combat took place.

ONCE UPON A TIME.... CHERNOBYL
It was 23 years ago.
None of the 99th ISTOM promotion were born yet. But still we all know what this name stands for.
Today we want to refresh your memory as we should never forget. We should draw the lessons from history. Let us pray that this never happen again.
Once upon a time.......
On 26 April 1986 took place the most serious civil nuclear incident in history. Explosions at reactor number four of the nuclear power plant at Chernobyl in Ukraine, a Republic of the former Soviet Union at that time, created a major nuclear emergency which had an impact over countries in Europe, and especially over large areas of Belarus, the Russian Federation and Ukraine. The Chernobyl disaster was a human tragedy, resulting in displacement of populations, and the contamination of large number of people and vast areas of land.
.An estimated 350 000 clean-up workers or "liquidators" from the army, local police and fire services were involved in cleaning up the radioactive debris during the 2 years that followed the incident. Many of them died of cancer or Leukemia due to the exposure to radioactivity. Over 490 0000 people were evacuated from the area surrounding the Chernobyl reactor to non-contaminated areas. A large increase in the incidence of cancer has occurred among affected people who lived in the most contaminated areas. This was due to direct exposure to radiations but also to radioactive deposits in pastures eaten by cows who then concentrated it in their milk which was subsequently drunk by children. Chernobyl may probably have also cause an increase of cancers in western Europe beyond Belarus, the Russian Federation and Ukraine.
Chernobyl had also an impact on mental health and psychological effects on the affected population. High levels of stress, anxiety and medically unexplained physical symptoms continue to be reported among those affected directly or indirectly by the disaster. Twenty three years after the incident, many people are still under schock. It is also reported that the designation of the affected population as “victims” rather than “survivors” has led to feelings of helplessness and lack of control over their future. This has resulted in individual destructive behaviours, such as the overuse of alcohol and tobacco, or the consumption of mushrooms, berries and wild animals from areas still having high levels of radioactivity.
Dear readers, do you know how many nuclear plants we have in France ?........................

Nuclear energy or no nuclear energy ? That is the question ...
The establishment of nuclear plants resulted in fierce debates amonst public opinion and politicians and major demonstrations in the world lead by the one opposed to the development of this type of energy. One could even say that these were at the origin of the development of the first "ecologist" and "green" contestation movements in Europe. Peace movements and also extreme leftist groups had also the nuclear as a common enemy, reflecting the interests of global capitalism.
Today the picture has evolved and many in the public have changed their mind with the new developments regarding on the one hand the concerns regarding the end to come of major fossile energy reserves ( oil and gas) and on the other hand the challenges of climate change due to the global warming.
Dear blog reader let us have a quick cartesian review of the matter to help us make our mind on a complex issue for which there is no simple answer.
Let us take as real life example: the case of France.
Did you know that our beloved hexagon is the 2nd world producer of nuclear energy ?
How comes ?
The facts are as follows: In the 70 's nuclear energy was covering 2% of our energy requirements and oil approximately 78 %.
Today nuclear energy covers 41 % of our requirements, oil 33% and gas 15 %, the rest being covered by hydroenergy and other renewable energies ( by the way France is also the first producer of renewable energy in Europe with wood counting for 55%, hydroenergy counting for 29 %, biofuels, 4% and solar + wind sadly representing only a bare 1% of total renewable energies). When came the first energy crisis in the 70's with the first time major increase of oil, the government decided to launch a major program of building of nuclear plants and the result is that today we have 58 nuclear plants scattered every where on our territory ( look at the map and try to find a place where to live if you are allergic to the vicinity of nuclear plants... you will not find it easy...).
From an economic and strategic point of view the political decision makers realized that France being one of the world major economy, (currently being the 7th bigger consumer of energy in the world) owns very limited fossile energy reserves. In fact, it is considered that France would own only 0.01% of fossile energy reserves of the world with little coal production left ( production decreased from 40 million metric tons per year in the 70's to less than 3 million metric tons in the years 2000), and very limited and decreasing gas reserves ( national gas production decreased from 15% of need in the 70's to less than 2% today). To ensure the energetic independance of the nation, the choice of nuclear energey appeared as THE solution and in fact today, thanks to this choice our country is independant for over 50% of its energy requirements and even generates major revenues from sale of electricity to european neighbours. The production of nuclear energy may also help the country meet the internationally agreed goals of 4 times reduction of CO2 gas emissions by 2050 and thus contribute significantly to reduction of global warming. Finally France has gained over the past almost 40 years a considerable "know how" in terms of nuclear technology and is now in a position to export it to many countries in the world that have indicated their interest to equip themselves with this new technology.
Let us review briefly the pros and cons of Nuclear energy:
The " pros"
- Energetic independance
- Technology of the future
- Alternative to decreasing world fossile resources
- Very limited impact on global warming
- Good source of export revenues
The "cons"
- Sophisticated Technology with major environmental risks and impact on human health ( remember Chernobyl) for a very long period of time.
- Problems of storage of residues
The next question may be: Do we have the choice or alternatives ?
The answer could be: yes we should definitely invest more in the research and development of other sources of energy; for the short term there is a lot of potential in developping more the use of non renewable energies such as the solar, the wind, the waves, the biofuels; for the long term to invest massively in the research on nuclear fusion ( the problem of energy would be resolved for ever... we can always dream...). We should also invest more on new modes of energy saving.
BUT for the very short term let us be realistic, we may not have other choice than to continue to rely on nuclear civil energy, particularly with current patterns of consumption and economic development. Should we decide to review the way our society is consuming,.... then it is another story..
We realize that this approach may not be very popular and we are looking forward to receive your views on the matter !

NUCLEAR EMERGENCY. WHAT FARMERS SHOULD DO TO MINIMIZE THE DAMAGES TO HUMAN HEALTH
Protect growing vegetables and animal fodder - cover with plastic sheets
Bring livestock in from pasture - move animals into a shed or barn;
Harvest any ripe crops and place under cover.
Do not consume locally produced milk or vegetables;
Do not process or distribute food products;
Do not fish, hunt or gather mushrooms or other forest foods.
Prevent the ingestion of contaminated herbage by grazing animals;
Prohibit hunting, fishing, mushroom collection, and consumption of vegetables and water derived from precipitations.
In potentially contaminated areas:
Do not use water for irrigation;
Do not burn vegetation or any material stored outdoors, including firewood.
The above measures may seem very simple, but do not forget that one of the major cause of contamination is due to the food ingested. It is important to control as soon as possible the risks of contamination at the level of food production. With this regard, it is reported that a large number of cancers would have been avoided after Chernobyl if the consumption of milk had been stopped immediately after he incident, which was not the case......
Future agrodeveloppers of ISTOM be aware and be prepared !

Dirty bomb ? What is this. Did you ever hear about a clean bomb any way?
A dirty bomb, or radiological dispersion device, is a bomb that combines conventional
explosives, such as dynamite, with radioactive materials in the form of powder. The idea behind a dirty bomb is to spread radioactive material into some populated area. This could contaminate buildings and the local environment, and expose people to radiation. Persons could be externally (skin) contaminated or internally contaminated …The main purpose of a dirty bomb is to frighten people by contaminating their environment with radioactive materials and threatening large numbers of people with
exposure. Such use of radiation is only hypothetical and has not been used by terrorists
before, but the possibility exists…. Dirty bombs are designed to spread fear and panic.
Dirty bomb vs atomic bombs in Hiroshima and Nagasaki
The atomic bomb explosions in Hiroshima and Nagasaki were nuclear weapons
involving a fission reaction.It caused severe harm,the death of hundreds of thousand of people and contamination of large areas. By contrast, a dirty bomb is not an atomic explosion,
it can only spread radioactive material and contaminate a relatively small area. Dirty
bombs are not weapons of mass destruction.
Their effect is expected to be very much less than of a
nuclear bomb (but still let us crossfingers)

The nuclear today
RED:Five "nuclear weapons states" from the NPT (USA, Russia, UK, France, China)
DARK YELLOW:Other known nuclear powers (India, Pakistan, North Korea)
LIGHT YELLOW: States suspected of having possession of, or suspected of being in the process of developing, nuclear weapons (Israel, Iran, Ukraine)
PINK: States which at one point had nuclear weapons and/or nuclear weapons research programs (Argentina, Brazil, Egypt, Germany, Iraq, Japan, Libya, Poland, Romania, South Africa, South Korea, Sweden, Switzerland, Taiwan).
the Nuclear Non-Proliferation Treaty (1970)
The objective of the treaty is to limit at most the number of the nuclear powers, by “forbidding any State endowed with nuclear weapons to transfer nuclear weapons or other explosive nuclear device and to help, neither to encourage, nor to incite in no way a State not endowed with nuclear weapons to make it or to acquire it. Besides, any State not endowed with nuclear weapons makes a commitment to accept of whoever it is the transfer of nuclear weapons and not to make them nor to acquire them. “
Major powers, which base their safety on them nuclear weapons and which continue to modernize their arsenal, have they the right to oppose that the other countries want to follow their example? These countries, besides weaker, do not they have too the right for the deterrence? There is an intellectual contradiction concerning the TNP, to allow making what we forbid to the others.
Furthermore, certain countries did not sign this treaty. Its rules do not thus apply to them. They are not official, but unofficial nuclear powers, and did not thus violate the international law by being equipped with an atomic arsenal

WHAT TO DO SHOULD THERE BE A NUCLEAR INCIDENT ? THAT IS THE QUESTION... WE'D BETTER BE PREPARED
Warning from blogmasters: To be on the safe side we would still advise you to consult with WHO if you are really concerned about this. ( we may have missed some important advice !).
First of all, what are the effects of a nuclear weapon?
The effects are the blast (destruction of buildings), heat (destruction or injury by high temperatures or fire), intense light (damage to eyesight) and radiation (causing acute radiation syndromes of different degrees of severity).
A detonation similar in size to the bomb that was dropped on Hiroshima could result in a high damage zone of a few kilometres radius where there would be few or no survivors. Detonating a nuclear weapon generates an intense and immediate radiation. A radioactive cloud is spread by the wind, possibly over large distances. The radioactivity can also contaminate food and water supplies if it deposits on crops, animal feed or in drinking water sources. Radioactive materials may be inhaled from the air or ingested in food causing internal radioactive contamination and damaging internal organs of the body. If radioactive materials come into contact with the skin it may cause radiation burns.
What protective measures can be taken ?
Protection from radiation involves four elements:
1) sheltering to reduce direct radiation exposure and inhalation of
any radioactive particles;
2) avoiding skin contact with objects contaminated
3) avoiding eating fresh foods or drinking from open water sources
unless absolutely necessary; and
4) treating open wounds as soon as possible to avoid bleeding and infections.
WHEN A NUCLEAR EXPLOSION OCCURS what should you do ?
If you are near the event at the time (within a several hundreds of meters or few km)
¤ Turn away and close and cover your eyes to prevent damage to your sight.
¤ Drop to the ground face-downwards and place hands under your body.
¤ Remain flat until heat and two shock waves have passed.
If outside during the blast
¤ Improvise a covering for your mouth and nose with a piece of clothe
¤ Move to a shelter, preferably located away from the direction that the wind could
be taking the radioactive material. Go to a basement or other underground area.
¤ Remove contaminated clothes, if possible take shower and change clothes prior
to entry.
If already in a shelter
¤ Stay calm, avoid panic
¤ Cover your mouth and nose with either a face mask
¤ Prevent entry of radioactive dust by shutting off ventilation systems and sealing

The material is formed by atoms.
A nuclear reaction is a conversion of one or several atomic nuclei.
It is the chemical reaction which concerns electrons or connections between nucleons.
- we speak about fusion when two atoms light unite to form a heavier, more stable nucleus.
- we speak about fission when a heavy nucleus breaks in two also more stable light nuclei.
The heat is produced during a break of an atomic connection.
This heat allows creating a current between a warm water and a colder water which makes turn turbines.
At present, the energy produced by our power station results from the nuclear fission, the nuclear fusion is not still mastered (see article on ITER)
