【摘要】 建造⁸⁰Co辐照装置一般采用水井式钢筋混凝土结构作为防护层。本文报道了一个以泥土层作防护的地下式⁶⁰Co辐照装置以及对其安全防护性能的监测。监测结果表明:辐照场所处环境位置符合卫生、达到安全要求;这种以少量钢筋混凝土作支架、大量泥土作防护层的地下式辐照场既能大大节约投资和建筑材料,又能达到良好的防护效果。更多还原

【Abstract】 The well-like structure of ferro-concrete was usually used as the protection layer in the construction of 60Co irradiators. In this paper, the design character of a 60Co irradiation device which was protected with soil layer under the ground and the result of its safety test were reported.更多还原
