基于FLUKA的质子加速器室屏蔽设计

Design of FLUKA-based Proton Accelerator Room Shielding

目的对某厂质子加速器室进行辐射防护屏蔽设计。方法采用FLUKA软件给出屏蔽墙厚度设计方案,并利用经验公式对其进行双重验证。结果结合十倍减弱系数,FLUKA软件给出的设计值偏保守,利用经验公式反推计算得到的屏蔽体外剂量率值低于设计值2.5μSv/h一个量级。讨论屏蔽设计方案合理可行,充分说明FLUKA软件在辐射屏蔽设计中的可靠性。

Objective: to design the radiation protection shield for the proton accelerator room of a factory. Methods: the thickness design scheme of shielding wall was given by FLUKA software, and double verification was carried out by empirical formula. Results: combined with tenfold weakening coefficient, the design value given by FLUKA software was conservative, and the dose rate value in vitro calculated by empirical formula was one order of magnitude lower than the design value of 2.5 μSv/h. It is discussed that the shielding design scheme is reasonable and feasible, which fully illustrates the reliability of FLUKA software in radiation shielding design.
