REVIEW OF THE METHODOLOGY FOR CALCULATING THE STATIONARY RADIATION PROTECTION OF THE ROOM WITH A LINEAR ACCELERATOR, BASED ON NCRP REPORT No. 151

The considered methodology for calculating stationary radiation protection is written in accordance with NCRP REPORT No. 151 “Structural Shielding Design and Evaluation for Megavoltage X- and Gamma-Ray Radiotherapy Facilities” [1]. The work presents partial calculations of the analyzed technique. A description of the approach used, conservative assumptions, basic coefficients and calculated values is given. It also analyzed the key points of NCRP Recommendations No. 151.
