Structural Shielding Design and Evaluation for Megavoltage X- and Gamma-Ray Radiotherapy Facilities
Jon S. Wilson
The purpose of radiation shielding is to limit radiation exposures to members of the public and employees to an acceptable level. This Report presents recommendations and technical information related to the design and installation of structural shielding for megavoltage x- and gamma-ray radiotherapy facilities. This information supersedes the recommendations in NCRP Report No. 49 (NCRP, 1976) pertaining to such medical radiotherapy facilities.
In addition, the use of barriers constructed with composite materials has become commonplace. This Report includes the necessary information for these higher accelerating voltages as well as a discussion of the various factors to be considered in the selection of appropriate shielding materials and in the calculation and evaluation of barrier thicknesses.
