Note: There are very few people who have to live with high levels of exposure to radioactivity. Radiation today is a trivial risk when compared to the other natural risks the planet has to offer. In any case, it is impossible to calculate the dose absorbed by any given individual as radioactivity is a fundamentally statistical phenomenon. With levels of radioactivity varying from village to village and beach to beach, how can one possibly calculate the total dose absorbed by a fisherman through the course of his life?
