If the Atomic bombs of Japan didnamp;#39;t stop rebuilding and repopulating why is Russia different? -

When Cherynoble blew up the whole area was contaminated for ever. why not Japan?

An A-bomb uses a small quantity of highly refined uranium or plutonium, and nearly all of that is instantly converted to far less dangerous elements in the blast. A breeder reactor like Chernobyl uses tons of much less refined uranium, and a meltdown slowly converts it to a witch s brew of nasty elements. Most of the damgage at Chernobyl is from radioactice iodine, which enters the food chain and hangs around from centuries. The blast at Chernobyl was a chemical explosion of non-radioactive hydrogen gas, not a thermonuclear explosion.

Believe it or not, the explosions in Hiroshima and Nagasaki where small compared to the Chernobyl meltdown. In the early day of nuclear weaponry, the explosive power was only a fraction of what is capable now.

Another aspect in 1945 was pure ignorance. The Japanese had very little knowledge of details such as the effects of radioactive contamination. Nobody had a secure understanding of the added dangers of these fairly experimental bombs.
