摘　　要：化学品船的储存罐罐壁要达到辐射屏蔽的指标,常规检测方法是用固体点源作测量源,检测罐表面的辐射强度.但这种方法难于检查船上不同位置的放射强度,文章通过理论计算得出相当的屏蔽效果要求,并采用与试验结果相结合的方法全面检查了储存罐壁的屏蔽指标,满足了实际检测的需要,避免了二次污染问题.The wall of the storage tank should reach the requirement to shield from the radiation.The normal way is to take a solid point as the radioactive source and measure the radioactive intensity of the storage tank＇s surfaces.But this method is difficult to inspect the radioactive intensity of different positions onboard.This paper gets the shield effect requirements by theoretical calculation and provides a way which combined the calculation and experiment to inspect the shield index of the storage wall.The data proved by the experiment can satisfy the needs for the detection and avoid the secondary pollution.
