【摘要】 本文叙述了一种用于测量中子剂量的“直接相互作用”型的CR-39塑料反冲径迹个人中子剂量计。该剂量计对²⁴¹Am-Be源的中子注量灵敏度约为（2.10±0.05）×10^-4径迹/n,可探测的中子注量下限约等于2.11×10⁵n/cm³,相应的中子剂量当量为7.81×10^-5Sv。总误差估计不超过±20％。更多还原

【Abstract】 In the paper a personnel neutron dosimeter based on a CR-39 plastic track detector registering heavy recoils and alpha particles is described. Experimental results show that the sensitivity of CR-39 detector to 241Am-Be neutron source is around (2.10±0.05)× 10-4 tracks per neutron. The limit of detection for the dosimeter is 7.81×10-5 Sv with a total error less than±20%.更多还原
