| 摘 要： | 中能重离子反应出射的中子具有较复杂的能谱,在穿过混凝土屏蔽层后,其能谱发生显著的变化。考虑到中子rem计的能量响应,在中能重离子反应出射中子理论计算能谱和角分布的基础上,估算了屏蔽层外中子能谱的变化和用10-in单球rem计在屏蔽层外测量中能重离子反应中子剂量当量时的理论修正系数。

| Abstract: | Neutrons produced in intermediate energy heavy ion reaction has rather complex energy spectrumand that will changes remarkably through the shielding. Consider the energy response of the rem--meter,one estimated the theoretical correction coefficient on measuring neutron dose equivalent for the inter-mediate energy reaction with the 10--in single--sphere rem--meter outside concrete shielding based uponthe theoretical neutron spectrum and angular distribution and upon estimated change of the neutronspectrum outside concrete shielding. |
