【摘要】 <正> 研究中子在生物组织中能量吸收情况时需要用制作探测器、模型等的组织等效材料。对这种材料的基本要求是:(1)它们在靠n-γ混合场中与n、γ射线的交互作用要类同于组织与n、γ的作用。要实现这一点最有效的办法就是使材料的原子组成与组织的一样或相当接近;(2)应有导电性;(3)要具有一定刚度、韧性。 多年来,进行这方面研究工作较多,比较活跃的是美国,其次是日本。到七十年代,组织等效塑料的研制日趋完善。更多还原

【Abstract】 A tissue equivalent conductive plastic made in our lab. is similar to A-150 in basic properties. The tissue equivalence and fabricating procedure of the plastic are described. The important properties of the a plastic are recounted and compared with some plastics similar to A-150, which were made by other lab.The density of the plastic is 1.11 ±0.01g/cm3. The electrical conductivity of it is 5.4cmΩ. It is lower than that published in ICRU report-26. The content of hydrogen in this plastic is the same as that in similar plastics within a range of±1%.更多还原
