A sPherical thin-wall ionization chamber has been developedas a laboratory reference for exposure measurement at radiation protectionlevel.The volume of the chamber is about 100 cm~3 and the backgroundcurrent is about 1×10~(-15)A in normal condition.The energy dependencenormalized to ~(60)Co is within 5% for energies ranging from 33 keV to 1.25MeV.As exposure rate greater than 10mR/h,the uncertainty of thechamber's calibration factgr was estimated to be±0.9% for above energyrange.And over the energy range,the intercomparison results of thechamber with IAEA dosimetry ladoratory were found to be consistentwithin 1.2% between them during the period of IAEA's Workshop andSeminar on SSDL's Calibration Procedure in Malaysia(1987).

本文介绍了一种可作为防护级照射量实验室标准的塑料薄壁球形电离室的设计和主要性能。该电离室容积为100cm~3;本底电流不大于1×10~(15)A;在33keV—1.25MeV 能区内的能量响应(以~(60)Coγ射线的响应归1)<±5%;在上述能区内,当照射量率为10mR/h时,校准因子的总不确定度(一倍标准差)估计为±0.9%,在近一年内的长期稳定性<±1.2%。该电离室于1987年 IAEA 关于次级标准实验室校准程序亚太地区比对研讨会期间与 IAEA 剂量实验室比对,在上述能区内与本实验室校准结果在1.2%内相符。
