International Council on Radiation

Recommended exposure limits are set by the US National Council on Radiation Protection (NCRP) and worldwide by the International Council on Radiation Protection (ICRP). The occupational exposure guidelines are 100 mSv in 5 years (average, 20 mSv per year) with a limit of 50 mSv in any single year. For the general public, the standard is 1 mSv per year. This must be put in the context of natural background radiation, which is approximately 3 mSv/year depending upon location (such as elevation) as well as other variables.

Within a few years of the discovery of radiation, the dangers of radiation exposure began to become apparent. As time passed and further information about the biological effects of radiation exposure was discovered, stan-dards-setting organizations, such as the International Council on Radiation Protection (ICRP), were formed to study data on the bi-...

Some cancers are caused by exposure to the sun or to naturally occurring radioactive isotopes. The estimated cancer incidence caused by these combined exposures is approximately 0.5 to 1.0 percent during a lifetime, with two-thirds of the exposure stemming from radon alone (Kocher and Hoffman 1991,1989 National Council on Radiation Protection and Measurement 1987,15,53 International Commission on Radiological Protection 1991, 188).

This group, created by Congress, collects, analyzes, develops, and disseminates information and recommendations on radiation quantities, measurements, and units. The National Council on Radiation Protection (NCRP) publishes maximum permissible levels of external and internal radiation. The major handbook is entitled. Maximum Permissible Body Burdens and Maximum Permissible Concentrations of Radionuclides in Air and Water for Occupational Exposure and Review of the Current State of Radiation Protection Philosophy. The NCRP suggests an annual permissible whole body dose of 5 rem per year, with 3 rem permitted within a 13-week period. 

The National Council on Radiation Protection and Measurements (NCRP) works to promote the importance of radiation protection and measurements. The council, established to represent all of the national radiological organizations in the United States on a collective basis, focuses on the science of radiation protection. The International X-Ray and Radium Protection Committee, created in July 1928, evolved into the International Commission on Radiological Protection. The NCRP originally operated as an informal association of scientists seeking to make available information and recommendations on radiation protection and measurements. The NCRP was reorganized and chartered by the US. Congress in 1964 as the National Council on Radiation Protection and Measurements.
