Structural shielding design and evaluation for medical use of X-rays and gamma rays of energies up to 10 MeV : recommendations of the National Council on Radiation Protection and Measurements

This report of the National Council on Radiation Protection and Measurements, which supersedes NCRP Report No. 34, is concerned with structural shielding design and evaluation for medical installations utilizing x-rays and gamma rays of energies up to 10 MeV. The report contains recommendations and technical information as well as a discussion of the various factors which must be considered in the selection of appropriate shielding materials and in the calculation of the barrier thickness. This report is mainly intended for radiological physicists, radiologists, and regulatory personnel who specialize in radiation protection. Sections of the report should be of interest also to architects, hospital administrators, and others who are concerned with the planning of new radiation facilities
