Is radiation levels safe in hiroshima today?

Question

thinking of going there for 3 weeks..but i will be staying in east hiroshima, which is 50km away from hiroshima city.

Answer 1

No, everyone there is DEAD.

Answer 2

Yes, it is relatively safe. When the bomb goes off, if it hits the earth, it will irradiate and activate that dirt and dust it kicks up. The Bikini islands have grown back for instance..but the coconuts are radioactive, since the soil is radioactive. That was also a surface burst because the bomb hit the atoll.

The Hiroshima bomb was an aerial burst, which means it detinated above land. This still would have produced the thermal damage of any other blast, but doesn't contact and activate debris that is blown into the atmosphere during a surface burst. Sure, at ground zero you might have elevated levels, but for the most part the land is livable.

Answer 3

I do not think there is any longer the threat of radiation in Hiroshima and Nagasaki. Please read the following about these cities ,after 1945:-

Hiroshima and Nagasaki since 1945

Both cities were rebuilt soon after the war and have become important industrial centres. The population of Hiroshima has grown to over one million and that of Nagasaki to 440,000. Major industries in Hiroshima today are machinery, automotive (Mazda) and food processing, those in Nagasaki are associated with its international port, particularly Mitubishi Heavy Industries.

Nuclear energy has come to be an important part of the life of each city in a totally new way: today one quarter of Hiroshima's electricity is from nuclear power and half of that for Nagasaki is nuclear. Both cities are testimony to the positive benefits of a technological society which applies available energy resources to the needs of urban populations and industry"

Answer 4

Yes. I believe they figured out that it was safe after about 35 years. Which was a real surprise, because the half life of plutonium is something like 95 million years. But our environment really is quite robust.
