Our daily exposure to radiation comes from numerous sources within our environment. The annual dose to which we are subjected depends upon where and how we live, and what we eat, drink, and breathe. This easy-to-use chart shows how to estimate that dose and compare it to the small amount of exposure found in the vicinity of a nuclear power plant. Suitable for student groups, discussion groups, exhibitions, and anywhere else that nuclear energy may be the topic of discussion. (Aimed at 5th grade through 12th grade levels.)
