Abstract
In order to study the shielding performance of the laminated plates with different core boards irradiated by the same strength ofγor neutron,the particle fluences of the three types of laminates which are Fe/W/Fe,Fe/Pb/Fe,and Fe/Pb-B-(CH2)n/Fe have been cal-culated.Taking Fe/Pb-B-(CH2)n/Fe as an example,the particle fluence is calculated when the thickness of the core board declines.The results indicate that,for the same thickness, the neutron shielding performances of the three laminates are Fe/W/Fe>Fe/Pb/Fe>Fe/Pb-B-(CH2)n/Fe,whileγshielding performances of the three laminates are Fe/W/Fe >Fe/Pb-B-(CH2)n/Fe>Fe/Pb/Fe.Also,when the thickness of the Fe/Pb-B-(CH2)n/Fe core board de-creases,its overall shielding effect does not change significantly.关键词
