Research on Radiation Protection of Proton Therapy Facility
-
Abstract
Proton therapy is currently one of the advanced tumor radiation therapy, but using proton therapy facility will produce radiation. In order to ensure its safe operation, environment and personnel by ionizing radiation meet the relevant national standards requirements, the proton therapy facility of radiation protection need to be considered. In this article, analysis of mechanism of proton therapy and shielding principle, the article puts forward the design method of radiation protection, which determine the radiation protection design goals, assess the source term, considering the convenience and safety of equipment use, engineering cost and other factors, shielding materials and parameters, the shielding calculation, set the safety interlock system and radiation monitoring system, and ensure that medical staff occupational exposure, satisfies the requirement of safety dose by public exposure of the masses.
