How far one should live from a Nuclear Power Plant? is 50 miles good enough

Is there any Nuclear Power Plant near the city or surrounding you live at least 50 miles away they say is the safest to live. This is probably not a question you're asked all that often. But it's one worth knowing the answer to for a couple of reasons: the basic value in knowing where some of your electricity comes from and, in the extremely unlikely event of a meltdown, the practical knowledge of whether you'll have to evacuate your home.

From what I understand, the likelihood of birth defects, cancers, etc. from living near ANY coal fired power plant is significantly higher than a meltdown in a nuclear plant. Meltdowns don't just happen; when considering them you also have to take into account the likelihood of natural disasters in your area. Coastal Japan? Maybe not great. I'd still take that over living near a coal plant, though.

> How large an area was affected by the radioactive fallout?

> Some 150,000 square kilometres in Belarus, Russia and Ukraine are contaminated and stretch northward of the plant site as far as 500 kilometres. An area spanning 30 kilometres around the plant is considered the “exclusion zone” and is essentially uninhabited. Radioactive fallout scattered over much of the northern hemisphere via wind and storm patterns, but the amounts dispersed were in many instances insignificant.

It's worth bearing in mind that:

    Before 1963, the United States and other countries conducted more than 500 nuclear weapons tests in the atmosphere. During these tests, radioactive particles and gases were spread in the atmosphere.

    Radioactive fallout was deposited all over the world, so many people were exposed to it. Even today, radioactive fallout is present in all parts of the world in small amounts.

Don't forget to compare the fallout from your nearest nuclear power plant to the radiation from radon gas expressed daily by your nearest granite outcrops. If you live in a valley with nearby granite it's quite likely your vally "fills" with radon gas every day when the winds are still and bows clear when the wind picks up.

Depends on if your water is coming from upstream or downstream. Ground water contamination is your biggest risk.
