DMC2000S电子个人剂量计校准装置的建立

Establishment of calibration apparatus for DMC2000S electronic personal dosimeter

依托DMC2000S型X、γ电子个人剂量计专用照射测读软硬件设备,建立了现场级别的DMC2000S电子剂量计校准装置,用于该型电子剂量计的现场校准。该校准装置采用标准仪器传递法,以校准的方式实现了量值溯源。校准装置的测量范围为10μSv^100 mSv,扩展不确定度为9.2%(k=2),符合该校准装置的使用目的需求,能满足JJG 1009—2006《直读式X、γ辐射个人剂量当量(率)监测仪》所要求的相关校准或检验项目的执行。

Based on the irradiation and measuring hardware and software specified for the DMC2000 S type X and Gamma electronic personal dosimeter,a calibration apparatus was established and used to calibrate the DMC2000 S electronic dosimeters as an on-site reference calibration standard. Applying the standard measuring instrument transfer method,the calibration standard achieved the unit traceability via calibration. With the measurement range of 10 μSv—100 mSv,and the expanded uncertainty of 9. 2%（ k = 2）,the calibration apparatus satisfied the usage requirements as well as the calibration requirements stipulated by the regulation of JJG 1009—2006 ＂Direct reading X and Gamma personal dose equivalent（rate） monitor＂.
