effective dose equivalent limit
effective dose equivalent limit (EDE limit)
the largest amount of ionizing radiation a person may receive according to radiation protection guidelines. It combines both internal and external dose and has replaced the concept of maximum permissible dose for occupational exposures. The EDE limit is prescribed for various organs as well as whole body and for various working conditions. The current EDE limit for occupational exposures is 100 mrem/wk (or 1 mSv/wk). The annual EDE limit is 5000 mrem/yr or (50 mSv/yr). Effective dose limits are regulated, and guidelines are published by the National Council of Radiation Protection (NCRP) and the FDA. Also called maximum permissible dose. See also dose equivalent.
