The U.S. Environmental Protection Agency (EPA) calculated in 2003 the primary sources of radiation in daily life:

Undergoing medical tests for gastrointestinal problems - 1,400 millirems

Radon radiation in average household - 200 millirems

Living a mile high in Denver - 81 millirems

Natural radiation in the human body - 39 millirems

Atmospheric radiation from outer space - 31 millirems

Mammogram - 30 millirems

Chest x-ray - 10 millirems

Living near a nuclear power plant - less than one millirem

The average U.S. citizen receives 360 millirems per year according to EPA, from a combination of the sources listed above.
