The National Council on Radiation Protection and Measurements (NCRP) published Report No. 48, Radiation Protection for Medical and Allied Health Personnel in 1976. Many changes in medical practice and procedures involving ionizing radiation have occurred in the intervening 13 years. As a result, the Council determined to prepare this new report to supersede NCRP Report No. 48. The primary objective of this new report is to update the material to include new radiation sources used in medicine. In addition, an attempt has been made to reflect current practice in medicine and present the material in terms readily understood by an audience, most of whom have limited expertise in radiation protection.
