They Don't. It is a huge issue for them and the world. Fukushima produces arounf 4,000 Roetgens per hour.
some might. for example the tamper of a "clean" hydrogen bomb might be tungsten instead of uranium to reduce fallout.
This is impossible to answer with any accuracy as it depends on too many variables, including:burst height/depthwind speed & directionprecipitation (causing rainout hotspots)low fallout (clean) or normal fallout or high fallout (salted/dirty) designFallout usually doesn't have a simple radius like blast & thermal, it comes down in an elongated plume driven by changing wind directions.
a standard fusion bomb using a uranium tamper. the tamper fissions, providing 90% of yield and enormous amounts of fallout. this is considered dirty. a clean bomb on the other hand sacrifices yield to reduce fallout by using non-fissionable materials in the tamper, like lead or tungsten.
Yes, nuclear power is still being used around the world as a source of electricity generation. Many countries have nuclear power plants that contribute to their energy mix. Despite concerns about safety and waste disposal, some countries continue to rely on nuclear power for its clean energy production capabilities.
You can't, it is always generated. However "clean" fusion bombs can be designed that reduce the fallout compared to a conventional fusion bomb of the same yield to about 5%. However the cost to build these "clean" bombs is significantly higher per megaton of yield than conventional fusion bombs.
Two countries that rely heavily on nuclear energy to generate electricity are France and the United States. In France, nearly 70% of the country's electricity comes from nuclear power, making it one of the most nuclear-dependent countries in the world. In the United States, nuclear energy accounts for about 20% of the total electricity generated and is the largest source of clean energy in the country.
Nuclear energy is not considered completely clean because of the risks associated with nuclear accidents, such as Chernobyl and Fukushima. Additionally, the mining and refining of uranium to fuel nuclear reactors can have environmental impacts, and the management of radioactive waste is a long-term challenge.
Most of the schools in Japan has no janitors. They let the students clean as a training for morality and discipline.
they buy it
Nuclear energy is very clean, provided you look after the spent fuel carefully, and follow good health physics practice during operation.
No. Japan is very clean and civilized.
If you mean nuclear power then:It is helpful because it has an almost infinite supply of fuel and is fairly clean energy, but if the protection from the radiation is defective it can spread harmful radiation all around the area, like in Chernobyl and Japan, although the former is a very extreme example.
