【摘要】 随着X、γ射线探伤机技术的发展,为适应检定、校准工作的要求,需对X、γ射线探伤机检定装置进行技术改造,更新标准器及配套设备,扩大测量范围,减小装置的测量不确定度,提高测量结果的准确性和工作效率,有效保障检定人员的辐射安全。技术改造后的检定装置满足国家计量检定规程对计量标准的技术要求,达到预期的目标。关键词更多还原

【Abstract】 With the development of technology of apparatus for X & γ radiography, the comprehensive techniques were improved on the verification device. In order to adapt the actual requirements of calibration and verification, the standard and related equipments were updated to expand the measurement ranges and decrease the uncertainty of the verification device, simultaneously, the accuracy of testing results and efficiency were enhanced accordingly, and the metrology personnel can keep away of radiation effectively. After improved, the technical requirements of the measurement standard were accorded with the national metrological verification regulation and achieved the desired objectives.更多还原
