Ozone Generation by Ultraviolet Lamps ^†

The COVID-19 pandemic has generated a great deal of interest in ultraviolet germicidal irradiation (UVGI) as an important means to disinfect air and surfaces. traditional lamp employed for UVGI been the low-pressure mercury-discharge that emits primarily at 254 nm photobiological band UV-C (100–280 nm). recent development even shorter-wavelength lamps, such Krypton–Chloride, 222-nm lamp, led greater concerns about generation ozone. It is well known wavelengths below 240 more readily generate However, there misunderstanding with regard actual dissipation ozone molecules by lamps. A review this subject much warranted. An overview various light sources presented give users better understanding risk how assure control when employing
