Air-kerma evaluation at the maze entrance of HDR brachytherapy facilities

Journal of Radiological Protection, 2014
In the absence of procedures for evaluating the design of brachytherapy (BT) facilities for radiation protection purposes, the methodology used for external beam radiotherapy facilities is often adapted. The purpose of this study is to adapt the NCRP 151 methodology for estimating the air-kerma rate at the door in BT facilities.
