摘　　要：目的分析我院各病区在用紫外线杀菌灯辐射照度分布状况及紫外线杀菌灯辐射照度随时间衰减规律。方法依据国家标准和行业规范,使用紫外线辐照计对紫外线杀菌灯辐射照度进行检测。在我院各病区随机抽样27个检测点进行检测,间隔3个月重复检测,记录并比较两次检测的辐射强度变化。对新购置的4支国产紫外线杀菌灯每隔48 h检测其辐射照度,连续监测1000 h,记录其辐照强度对时间的变化数据。结果我院在用紫外线杀菌灯两次检测合格率分别为62.96%和37.04%。新紫外线杀菌灯的辐照强度整体上随时间变化呈现逐渐衰弱的趋势。结论紫外线杀菌灯作为医疗机构普遍使用的物理杀菌方式,其辐射照度必须定期检测,以保证相应医疗区域的洁净。Objective To analyze the irradiance distribution of ultraviolet germicidal lamps in use in each ward of our hospital and the attenuation changes of ultraviolet germicidal lamps with time. Methods According to the national and industry standards, and the irradiance of ultraviolet germicidal lamps was determined by ultraviolet irradiance meter. A total of 27 randomly sampled ultraviolet germicidal lamps were tested in each ward of our hospital, and repeated tests were performed after 3 months. The changes in radiation intensity of the two tests were recorded and compared. For the newly purchased 4 domestic ultraviolet germicidal lamps, their irradiance was detected every 48 hours, and the continuous monitoring was conducted for 1000 h to record the change of their irradiation intensity to time. Results The qualified rates of ultraviolet germicidal lamps in use in our hospital were 62.96% and 37.04%, respectively, at the interval of 3 months. The irradiation intensity of the new ultraviolet germicidal lamps showed a gradual decline with time. Conclusion Ultraviolet germicidal lamps serve as the physical germicidal means commonly used in medical institutions, its radiation illuminance must detect regularly, in order to assure the cleanness of corresponding medical area.
