Estimate your personal annual radiation dose.

We live in a radioactive world-humans always have. Radiation is part of our natural environment. We are exposed to radiation from materials in the earth itself, from naturally occurring radon in the air, from outer space and from inside our own bodies (as a result of the food and water we consume.) This radiation is measured in units called millirems (memes). The average dose per person from all sources is about 620 mrems per year. It is not however, uncommon for any of us to receive less or more that that in a given year (largely due to medical procedures we may undergo. Standards allow exposure to as much as 5,000 mrems a year for those who work with and around radioactive material.*   Print out the following chart to figure your annual radiation dose:
