Yes. there still is
it is reported to be around 220svr
It had been decades without the radiation from the nuclear bomb at Nagasaki.
The readings were very high.
The radiation levels of atomic bombs vary according to the amount of radioactive elements put into the bombs or missiles and if they are actually used. Once the radioactive matter is inside the bomb housing the radiation levels are negligible but once one of the nuclear bombs is used then the variables come into play. (see related link below to see how complex it is) Consider this: the atomic bombs dropped on Japan in 1945 are 1/10th the killing power of today's nuclear missiles. If one modern nuclear missile were to be used today the bomb would be able to kill about a third of the world with the initial bomb blast and radiation fallout. The radiation level after Hiroshima and Nagasaki was not really measured until after the US occupied Japan. The Japanese leaders did not really understand the radiation fallout and poisonous danger and they did not use radiation detectors right after the blast. It is rumored the radiation levels were 100 times today's acceptable levels of radiation.
japans level of development is the industrail stage. It is a highly developed country.
Atomic bomb
220svr
For many years, there was radiation in the air in Japan from the dropping of atomic bombs on Hiroshima and Nagasaki. However, Japan is perfectly safe to visit today, with no risk of radiation poisoning.
The bombing of Japan at the end of WWII killed MANY PEOPLE because of the nuclear radiation
Radiation decays at a set rate. For example, if the level of radiation today is 5000, then in 1000yrs, it'll be a level of 2500. In 5000yrs, it'll be a level of 2000 and so and so on. The radiation in Chernobyl and Japan will remain there for hundreds, if not thousands and thousands of years. Because of this rate of decay that slows over time, depending on the size of the radioactive sample, it could take decades.
No, Hawaii is currently not in danger of radiation from the incidents involving the nuclear reactors in Japan.
No, the seafood in Costa Rica has not been contaminated by radiation from Japan's disaster. Costa Rica is very far from Japan.
Small amounts of radiation from damaged nuclear plants in Japan have already reached California but they pose no health threats at all. Any radiation that reaches California from Japan is well dissipated by the time it gets there.
Mostly people in Fukushima since that is where the Radiation Plant is.
look at Japan.
radiation
Of course there is. That was a massive explosion that spewed radiation for miles.
radiation can be slowed by the using of salt.take example by people in japan
