"In the months after the explosion, attention turned to removing the radioactive debris from the roof.[100] The worst of the radioactive debris was collected inside what was left of the reactor, however it was estimated that there was approximately 100 tons of debris on that roof that resulted from the explosion and which had to be removed to enable the safe construction of the 'sarcophagus' – a concrete structure that would entomb the reactor and reduce radioactive dust being released into the atmosphere"
"If a bomb was detonated in the air, like the two which were detonated in Japan, the hot, radioactive ball of fire travels up high into the stratosphere. It does this quickly, usually within minutes. The cloud then cools down and begins to look like a regular (albeit irregular shaped) cloud. But don’t let this fool you, it is still hot and radioactive. Prevailing winds will blow this cloud over a huge area. The residual heat and lightness of the particles will keep it in the atmosphere for a few weeks, after which, the particles begin to “fall out” and come back down to earth. By this time, the radioactive particles have been dispersed and diluted over a thousands of square miles with the most dangerous radioactive elements already rendered inert by decay."
