ebel: 1s! B, NATIONAL COUNCIL ON RADIATION PROTECTION AND MEASUREMENTS* (NCRP). The NRCP was chartered‘by Congress in 106! to collect, analyze, develop, and disseminate information and recommendations about protection against radiation, radiation protection measurements and units, and to provide a means for cooperation between organizations concerned with radiation protection.

To establish criteria, NCRP uses the concept of "acceptable ~ risk"' (where the risk is compensated by a demonstrable benefit) broken down to fit classes of individuals or population groups exposed for various purposes to different quantities of radiation.
