目的对某企业使用的手持式X射线荧光分析仪放射防护水平进行检测评价,了解分析仪对劳动者健康可能造成的影响。方法使用射线巡测仪对荧光分析仪周围空气比释动能率进行测试。结果该X射线荧光分析仪周围空气比释动能率符合标准要求,但在结构及安全联锁等方面不完全符合标准关于敞束型分析仪的防护要求。结论该企业所用X射线荧光分析仪可以安全使用,但为确保职业人员和周围公众安全,仍需进一步改进。
Objective To evaluate the radiation protection level of hand-held X-ray fluorescence analyzers used by an enterprise to understand the possible impact of the analyzer on workers’ health. Methods Radiometer was used to test the air kerma ratio around the fluorescence analyzer. Results The specific energy of air around the X-ray fluorescence analyzer met the standard requirements, but the structural and safety interlocks did not fully meet the standard requirements for the safety of the open-beam analyzer. Conclusion X-ray fluorescence analyzers used by the company are safe to use, but further improvements are needed to ensure the safety of the occupational personnel and the public at large.
