Biological shield design for a 10 MeV Rhodotron

Radiation field of the Rhodotron-TT200 electron accelerator is determined in this study. Regarding the interactions of electron with matter, the produced radiations and their attenuation to the permitted level (i.e. 0.01 mrem/h) are evaluated and calculated. For this purpose analytical calculations are applied to determine the biological shield material and thickness. In order to make sure of results accuracy, Rhodotron accelerator and its shielding are simulated using MCNPX code and the results of analytical calculations and MCNPX code are compared with the experimental ones.

► We evaluate the produced radiations of the Rhodotron-TT200 and their attenuation to the permitted level.
► We apply analytical calculations to determine the shield material and thickness.
► We simulate the Rhodotron accelerator and its shielding using MCNPX code to make sure of results accuracy.
