摘　　要：目的了解军队餐饮单位更换新购合格紫外线消毒灯管辐照强度偏低原因,并采取有效措施。方法采取逐一排查方式,在排除电压、温度、湿度及紫外线灯本身质量等原因后,将本部新购合格、餐饮单位和医疗机构使用500 h以内、40 W紫外线灯管30支,分别在不同品牌电感或电子类灯架上进行测试,测定其紫外线辐照强度。结果电感组灯架紫外线灯辐照强度明显高于电子组,同一灯管在不同灯架测试的最大差值为44μW/cm^2;电感组不同品牌灯架紫外线灯辐照强度最大差值为30μW/cm^2;电子组不同品牌灯架紫外线灯辐照强度最大差值为34μW/cm^2;其中A牌电感灯架辐照强度最高,X牌电子灯架辐照强度最低。结论用科学手段查清了紫外线消毒灯管辐照强度偏低除与灯管质量、清洁度及环境因素有关外,灯架种类也是一个重要因素,为日常卫生监督指导提供了技术支撑。Objective To investigate the reasons for low radiation intensity of standard UV disinfection lamps in military catering units so as to take effective measures accordingly. Methods After causes associated with voltage, temperature, humidi- ty, quality of ultraviolet lamps were excluded, the ultraviolet radiation intensity of thirty newly-purchased 500 h, 40 W UV lamps, which were used in catering units and medical institutions, was tested using different brands of induetors or electronic lamp holders respectively. Results The ultraviolet radiation intensity of lamps in inductance group was significantly higher than that of the electronic group. The maximum difference of the same lamp on different light holders was 44 txw/cm2. The maximum difference in ultraviolet light irradiation intensity between different brands of lamp holders was 30 I^w/cm2in inductance group and was 34 μw/crn2 in the electronic group. The inductance lamp holder of Brand A had the highest degree of irradiation while that of Brand X had the lowest. Conclusion Except for the lamp quality, cleanliness and environmental factors, the lamp holder is an important determinant of irradiation intensity of ultraviolet disinfection lamps. This result provides a technical support for daily sanitary supervision.
