Research on calibration method of 222nm UV radiometer
The ultraviolet (UV) light at 222nm can be absorbed by microbial DNA and RNA, changing their structures and achieving the effect of sterilization. Unlike commonly used UVC light, 222nm UV light is harmless to humans, making it a crucial role in disinfection and sterilization. Consequently, calibration of 222nm UV radiometers is also of great significance. In this paper, according to the characteristics of KrCl excimer lamp, the effects of different types of filters on the spectrum of sterilization lamp are studied, as well as the calibration method of UV radiometer, and the measurement uncertainty is evaluated.
