紫外线灯辐照强度监测管理中的问题

Radiant Intensity of Ultraviolet Lamp:Detection and Management

目的提高紫外线灯管辐照强度监测准确性,保证紫外线灯消毒效果有效性。方法根据紫外线灯管使用中不同时间段,用紫外线辐射照度计进行强度监测,评价使用中紫外线灯监测的辐照强度与继续使用的有效时间。结果保证紫外线灯管质量基础上,按每天照射1h计算,灯管监测强度≥90μW/cm2时,可持续使用1年,监测强度≥80μW/cm2时,可持续使用6个月,监测强度80～75μW/cm2时,可持续使用3个月,监测强度75～70μW/cm2时,可持续使用1个月,辐射强度监测不得<70μW/cm2。结论采取紫外线灯照射强度监测与参照灯管使用时间(频次),实行定期监测的方法是可行的,此方法真实可靠、简便、易掌握,避免造成浪费,保证紫外线灯消毒效果的有效性。

OBJECTIVE To improve the accuracy of the radiant intensity detection of ultraviolet lamp and ensure its disinfection effect.METHODS At the different time after use of the ultraviolet lamp,its radiant intensity was measured by using the luminometer,and estimated.RESULTS If the ultraviolet lamp with good uality and worked one hour each day,with detected intensity ≥90 μW/cm^2,it could be used one year continuously,when ≥80 μW/cm^2,it could be used 6 months continuously,and when 80-75 μW/cm^2,it could be used 1 month continuously.The lump＇s detected intensity must be exceeded over 70 μW/cm^2.CONCLUSIONS The method that detecting the radiant intensity of ultraviolet lamp in scheduled time and consulting the used time of lump is viable.The method is real,simple,convenient and easy manipulated and ensures the effectiveness of disinfection by using ultraviolet lamp.
