简述了一种适用于舰艇环境的核辐射剂量仪设计,可用于测量舰上环境γ辐射剂量率和剂量,也可测量人员剂量(主要记录瞬发γ和中子剂量)。分体式的设计,使得用于人员剂量测量的剂量计体积小巧,可佩戴于手腕,最大限度减小对舰员工作的影响。经过强化电磁兼容和整机密封性设计后,能够在舰载条件下稳定工作。试验结果与国外同类仪器比对表明,该仪器具有多方面优势。
A nuclear radiation monitoring instrument applicable to marine is introduced. It can be used to measure the on-board radiation dose rateand dose, andalso the personal dose (instantaneous γ and neutron dose). The segmented design makes the dosimeter used for personnel dose measurement small in size and can be worn on the wrist to minimize the impact on the crew's work. After strengthening electromagnetic compatibility and sealing design of the whole instrument, it can work stably in marine environment. Comparison with foreign similar equipment shows that the instrument has many advantages.
