Total Annual Dose: 315 mrem

Notes:

  • The amount of radiation exposure is usually expressed in a unit called millirem (mrem). In the United States, the average person is exposed to an effective dose equivalent of approximately 360 mrem (whole-body exposure) per year from all sources (NCRP Report No. 93).]
  • The dose calculator is based on the American Nuclear Society's brochure, "Personal Radiation Dose Chart". The primary sources of information we relied on are the National Council on Radiation Protection and Measurements Reports 92-95, and 100. Please remember that the values used in the calculator are general averages and do not provide precise individual dose calculations.
