Radiation Protection in the Design of Radiotherapy FacilitiesProvides practical guidance regarding the design and shielding of radiotherapy facilities. Methods for determining the necessary structural shielding for external beam units (cobalt-60 units, linear accelerators, superficial and orthovoltage units, and simulators), as well as for brachytherapy units, are described. |
