Nuclear power plants are the major source of electricity. USA is having around 115 N reactors, Japan, such a small country has around 46-48 reactors. There can be no precautions that could be taken in order to avoid nuclear radiation, in fact, there is a trivial amount of radiation emitted from an operating nuclear plant.I think that radiation exposure can be perfectly safe providing the level is low enough, because zero exposure is simply not possible. You and I are exposed to several sources of background radiation like cosmic rays, fossils, etc on a constant .Radiation also reaches us from outer space, and it comes up from the ground. It varies from place to place, but thereâs nowhere on earth that you can avoid it. Medical procedures, such as x-rays and scans, also contribute to our exposure.What about nuclear power stations, how much radiation do we get from them? Not much. About 0.014%. That means that, of your daily dose of radiation, nuclear power accounts for 12 seconds worth. Nuclear power plants may actually reduce your radiation exposure, because the fossil fuels they displace emit more radiation than they do!
So, you and I are surrounded by radiation, wherever we are and whatever we do. Itâs not because we have nuclear power stations, either, the dose they give us is nothing to worry about.
Hope this helps.
