| 本文以在高辐射剂量场下设计一种声音传感器的辐射屏蔽筒为主要目的.在总活度为1016 Bq数量级的钴源环境下，以筒状屏蔽体的材料体积限值V0=960 cm3为条件，对屏蔽体的相关长度、角度参量值进行合理优化，通过MCNP程序的运算，得出探测器的壁厚l、窗厚s、传声孔夹角β与其内部传感器受照辐射剂量率D·的对应关系，并依据模拟结果，初步验证了柱状屏蔽筒作为高辐射场下屏蔽γ射线的模型所具有的合理性。 |

| In this paper,we designed a radiation sheilding column for an acoustic sensor used at high intensity radiation circumstance.MCNP is being used as a simulation-computation software to set up the model of the irradiation chamber and calculate absorb dose rate of the sensor （D·） corresponding to each parametry array of wall thickness（l），window thickness（s），soundhole angle（β） on the premise that colunm volume V0 equals to 960 cm3,with 60Co,as the source which radioactivity reaches to 1016 Bq orders of magnitude.Finally rationality of the column in sheilding γ-rays was proved by the calculated results. |
