本文描述了由核-2乳胶片(厚度为50微米)和塑料暗盒组成的快中子个人剂量计。对能量为2.4,3.6和14兆电子伏的中子,其探测效率分别为7.7×10~(-4),8.3×10~(-4)和11.3×10~(-4)径迹/中子;采用防潮措施后,在温度为35±1°C,相对湿度为95%的环境条件下,一个月的潜象衰退率为10%;剂量计耐γ辐射可达到10伦。在测量相应于最大容许月剂量(1.2生物伦琴当量)的快中子剂量时,给出的精确度为±20%。 This article describes a fast neutron personal dosimeter consisting of a core-2 latex film (50 microns thick) and a plastic cartridge. The detection efficiencies of neutron with energy of 2.4, 3.6 and 14 MeV are 7.7 × 10 -4, 8.3 × 10 -4 and 11.3 × 10 -4, respectively After the moisture-proof measure is taken, the recession rate of the latent image for one month is 10% under the environmental conditions of the temperature of 35 ± 1 ° C and the relative humidity of 95%; The accuracy given is ± 20% when measuring the fast neutron dose corresponding to the maximum allowable monthly dose (1.2 bioRenQin equivalent).
