摘要
在分析重离子核反应中中子的产生和有关保健物理数据的基础上,确定了用于屏蔽计算的核反应系统和计算参数,计算了单核能为100MeV、束流强度为3.9×10^(11)离子/s的^(12)C离子轰击Cu靶时距靶5m和10m处达到不同中子剂量当量率时需要设置的混凝土(ρ=2.3g/cm^3)屏蔽厚度。
Based on analysis for the neutron production in heavy ion interaction andsome health physics data the parameters for the shielding calculation are deter-mined The thickness of ordinary concrete shielding corresponding to differentneutron dose equivalent rates at 5m and 10m from target are calculated for a Cutarget bombarded with ^(12)C ions of energy of 100 MeV/u and beam current of3.9×10^(11) ions/s.
