Nuclear Holocaust In Japan :
In 1945, two nuclear bombs were dropped on Hiroshima and Nagasaki cities in Japan. This holocaust killed about 100,000 people and totally destroyed the city. This Explosion emitted forceful neutrons and gamma radiations. The radioactive strontium (St*90) liberated in the explosion resembles calcium and has the property of replacing calcium in the bones. As a result large scale bone deformities occurred in the inhabitants of these cities.
Chernobyl Nuclear Disaster :
On April 26th 1986, the world worst nuclear explosion occured in one of the reactors in Chernobyl power plant in Ukraine. The disaster was caused mainly due to poor reactor design and human error.
Impacts :
Chernobyl accident killed more than 20,000 people and 3.5 million people have suffered ill because of the accident. Nearly 1,35,000 people had to be evacuated at around Chernobyl.
The accident occurred, when the workers were putting uranyl nitrate solution containing about 16.6 kg of Uranium, which exceeded the critical mass, into the precipitation tank. Since the tank was not designed to dissolve this type of solution, the workers and residents in the surrounding are exposed extremely to high level radiation.
