What does nuclear fallout do to your body?
As to the health concerns, the problem is that nuclear fallout contains radioactive heavy elements, which decay by sending out streams of high-energy particles over time. When those energized particles hit the DNA in our cells, they wreak biological havoc, causing cancers and other diseases.
How much can the largest nuke destroy?
Tsar Bomba unleashed almost unbelievable energy – now widely agreed to be in the order of 57 megatons, or 57 million tons of TNT. That is more than 1,500 times that of the Hiroshima and Nagasaki bombs combined, and 10 times more powerful than all the munitions expended during World War Two.
