title: A general solution to the shielding of medical x and gamma rays by the NCRP Report No. 49 methods.
abstract: A general method for extending the principles and techniques of NCRP Report No. 49 of the National Council on Radiation Protection and Measurements has been developed. Equations are derived that determine the photon exposure through a radiation barrier taking into account the primary, scatter and leakage radiation from multiple radiation sources of various beam qualities. Applications of this include a general solution for medical radiation structural shielding and an analysis of commonly used diagnostic radiology shielding tables.
