Dirty bomb ? What is this. Did you ever hear about a clean bomb any way?


are you interested to know what is a “dirty bomb”?

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)
