Report No. 049 – Structural Shielding Design and Evaluation for Medical Use of X Rays and Gamma Rays of Energies up to 10 MeV (1976)

This Report supersedes NCRP Report No. 34, and 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. Recent availability of new data used to calculate the shielding requirements has resulted in revision of some of the shielding requirement tables set out in Appendix C. Specific values of the parameters used in the formulation of the tables are explicitly given. The calculational procedures are presented in such a manner as to facilitate their use in deriving customized shielding requirements not to be found in the tables.
