PERSONAL RADIATION DOSE CHART


We are all exposed to radiation all the time...from the starts, from food from water.

But HOW MUCH? and from WHAT?

We live in a radioactive world-always have. Radiation is all around us as a part of our natural environment. It is measured in terms of millirems (mrems). The annual average dose per person from all sources is about 360 mrems, but it is not uncommon for any of us to receive far more than that in a given year (largely due to medical procedures we may have done). As an example, international standards allow up to 5,000 mrems a year exposure for those who work with and around radioactive material.

*Some of the radiation sources listed in this chart result in an exposure to only part of the body. For example, false teeth result in a radiation dose to the mouth. The annual dose numbers given here represent the "effective dose" to the whole body.

**The value is less than 1, but adding a value of 1 would be conservative.

***These are yearly average doses. If you have had many such procedures, your dose would be much greater.
