Radiant Intensity of Ultraviolet Lamp:Detection and Management / 中华医院感染学杂志

ABSTRACT

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 ?W/cm2,it could be used one year continuously,when ≥80 ?W/cm2,it could be used 6 months continuously,and when 80-75 ?W/cm2,it could be used 1 month continuously.The lump's detected intensity must be exceeded over 70 ?W/cm2.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.
