Radiation Dose Chart

The average [radiation] 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 than that in a given year (largely due to medical procedures we may undergo). International Standards allow exposure to as much as 5,000 mrems a year for those who work with and around radioactive material.

You can calculate your annual (including background radiation) exposure at http://www.ans.org/pi/resources/dosechart/

The folllowing chart describes acute radiation poisoning. Please note that it describes exposure measured in milliSieverts (mSv), and not millirem (mrem) as in the values above.
