研究了应用ＣＲ３９ 探测器测量中子剂量的方法、蚀刻条件、刻度和实际应用。结果表明最佳蚀刻条件为：６５ ｍ ｏｌ／Ｌ ＫＯＨ、７０℃、７ ｈ，刻度系数为７０×１０－ ３ ｍ Ｓｖ／（径迹数·ｃｍ － ２），最低可探测下限为００６ｍ Ｓｖ，可用于一般中子γ混合辐射场中中子剂量的测量。
The method of measuring neutron dose by CR39 detector, etching conditions, graduation and practical application are studied. The results show that the best etching conditions are as follows: 65mol / L KOH, 70 ℃, 7h, the calibration coefficient is 7.0 × 10-3 mSv / (track number · cm - 2), the lowest detection limit Is 006m Sv, which can be used to measure the neutron dose in the general neutronγ mixed radiation field.
