Abstract:
First designs of radiotherapy department was based on the empirical formulas. Advanced recommendation were introduced through National Council on Radiation Protection (NCRP) report No 49 related to the design and installation of structural shielding. Accelerating voltages of 10 MV was maximum that was covered in that report. After this report there were several recommendations resulting with the NCRP report No 151. This Report includes the necessary information for 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. Equivalent European protocol is International Atomic Energy Agency (IAEA) Safety Reports Series No 47. Purpose of this paper is to check wheter the tickness of the bunker is enough to limit radiation exposures to members of the public and employees to an acceptable level in the Center for Radiotherapy. Calculation of the wall tickness was done following the NCRP 151 protocol. Results are showing that the wall thickness is adequate for accelerating voltages of 6MeV.
