Use on Coronavirus
The following information has been published by ResearchGate.net regarding the sensitivity of coronavirus to UV radiation.
Table 1 above summarizes the results of studies that have been carried out on coronaviruses under exposure to UV radiation, with the specific species indicated in each case. The D90 value indicates the UV dose for 90% inactivation. Although there is a wide range of variation in D90 values, this is typical of laboratory studies on UV sensitivity. The range of D90 values for coronaviruses is from 7 to 2410 J/m2 , with an average of 308 J/m2 , which should adequately represent the UV sensitivity of SARS-CoV-2 (COVID-19). By using these exposure data and comparing the irradiance measurements of the UV radiation from our lamps and UV disinfection systems, we can easily calculate the exposure times required to achieve a particular logarithmic reduction based on specified distances from the source.
