First of all, don't tell me about some minuscule amount of radiation found anywhere that is 1000 times below the minimum standard of danger. If I get more radiation walking in the sunshine without sunblock, then I don't need to hear about it!
Second, please distinguish between exposure to radiation (the stuff that comes flying out of radioactive material and is only harmful if you stand in the line of fire) and radioactive isotopes (which you might ingest and thus expose yourself to its radiation for as long as the isotope exists in your body). No one is finding radiation from the nuclear reactors miles away - it's all been absorbed by then. What you may find is radiation coming from radioactive isotopes which may have come from the damaged power plant! Don't confuse an author for his book and don't confuse some words and phrases found in isolation with an entire book.
