摘　　要：目的对EQF3120氡及其子体测量仪的测量效果进行验证和比较,以了解仪器性能与测量效果。方法仪器的校准在标准氡室进行,比对和应用选择典型房间,采用同类型仪器进行现场测量。结果在标准氡室选择的高、低氡(CRn)和氡子体潜能浓度(Cp)EQF3120对两者的校准系数分别为1.16,1.13和0.97,0.95;现场比对结果的比率在1.10,1.12和0.95,1.07。结论本测试结果表明,EQF3120氡及其子体测量仪可同时测量CRn、CpRn和CpRnDu等多项指标,所得结果与国内外同类探测器有较好的可比性。Objective To evaluate the performance of EQF 3120 radon/radon progeny monitor.Methods The equipment was calibrated in radon chambers and used to measure radon and radon progenies in basement or similar rooms.The results were compared with those measured by similar equipment.Results The correction factors of EQF 3120 for radon（CRn）and radon potential alpha energy concentration（CpRn）of high and low concentrations in radon chamber were 1.16,1.13 and 0.97,0.95 respectively.The ratios of the field comparisons were 1.10,1.12 and 0.95,1.07.Conclusion CRn,CpRn and CpRnu could be measured simultaneously by EQF3120.The results were consistent with those measured by other similar equipment.
