The answer isn't a clear number. They say it takes about 40-50 years for nuclear radiation to effectively drop to safe levels or safe-ish. It's all science talk about the half-life of radioactive atoms. Every X amount of years the atoms energy is cut in half. At least that is a gross generalization of it.
The effects are still apparent today though. Many Japanese are still born with birth defects or problems due to radiation. When you get radiation sickness, it can structurally change your DNA, in turn you can pass it to your kids. Born without arms, legs, etc.
It's really an awful thing, Japan is an awesome country. I've never been but I want to go there lol. They have an awesome culture.
Look up the nuclear reactor meltdown of chernobl (that's probably not a correct spelling). They've got a documentary on it on Netflix. Similar but more lasting effects I think because it was a plant not a bomb.
Not at all, Japan makes no nuclear bombs. The only ones used on Japan (2) were back in 1945, long before the current generation of Japanese were born.
I think they are still testing
Not a good place to be as they have had a 8.9 earthquake and a tsunami and three nuclear reactors have exploded so in my opinion i wouldn't suggest it. It will take the Japanese a long time to recover from this
The nuclear fuel rods in the BWR design in Japan are about 12 feet long.
No, it is perfectly legal as long as it is used on your own property.
The long term result of the use of the Atomic bomb by the US in WW2, has been building new and larger nuclear weapons/bombs. Despite the advances in nuclear activity, it can clearly be seen that the "fear" of using the mass destruction of nuclear weapons has been that no more nuclear or atomic bombs have ever been used again.
There were none left. Once the two bombs were dropped on Japan, there were none left in reserve. It would have taken a long time to build and create new ones.
If there is a nuclear bomb that explodes you will not be able to protect yourself. It will destroy and contaminate all of the surroundings for a long distance depending on the size of the bomb. Even several years of Iwo Jima and Hiroshima that are still people affected by the bombs.
Easy. Basically there were two types of nuclear bombs (Atomic bombs). One is fusion and the other is fission. Fusion bombs are Hydrogen bombs that were only invented and tested on 1950s. When America drop the bombs on Japan , it was fission type. Both Uranium and Plutonium in Hiroshima and Nagasaki respectively.
if there was a atomic bomb then it could last for weeks and daysthe effects on people could last for years
Long before the first one was made. That was the purpose of making them: to have a very dangerous bomb (all bombs are dangerous).
Nuclear fusion. Stars like the sun are basically hydrogen bombs at their core. Hydrogen bombs are fusion bombs, building heavier elements up from hydrogen in their high pressure and temperature cores. All the chemical elements in your body apart from hydrogen were built up in stars that exploded long, long ago,
