Comparing the Impact of Far UVC and Germicidal UVC on Disinfection

Within the germicidal UVC range, 260 nm to 270 nm is seen as an ideal wavelength, with only a small drop in efficacy in damage to the nucleic acid across that wavelength range (peak DNA/RNA absorption is observed between 263 nm to 265 nm) while, outside that range, the efficacy of longer or shorter wavelengths starts to fall drastically.

For comparison, UVC in that range is two to three orders of magnitude more effective than UVA at inducing DNA damage.

The primary process of disinfection in the germicidal range is by the generation of cyclobutane pyrimidine dimers (CPD), the dominant form of UV-induced genomic damage. These dimers interrupt the replication of DNA/RNA and lead to bacterial cell death and viral inactivation.

Recently, scientists have studied the application of Krypton-Bromine and Krypton-Chlorine excimer lamps to generate primary photon emission peaks at 207 nm and 222 nm, respectively. UVC in the 207 nm to 222 nm range is commonly referred to as Far UVC. While photons emitted in this range are absorbed to some degree by the nucleic acids of DNA/RNA, the principal factor in reducing infectivity is thought to result from absorption and resultant damage to proteins. This has been demonstrated notably on adenovirus, methicillin-resistant staphylococcus aureus (MRSA), and influenza virus of type H1N1.

In water applications, the use of 222 nm does not seem likely since the UV transmissivity (UVT) in water becomes unacceptably large. UVT for filtered water is approximately constant down to 260 nm and starts to drop dramatically at shorter wavelengths due to common chemical contaminates such as nitrates. In addition, the pathogens of interest are biofilm-forming bacteria such as pseudomonas with peak absorption between 260 nm to 265 nm which exhibit lower photon absorption at shorter wavelengths.

Employing a 205 nm to 230 nm photon source(far UVC disinfection gate 222nm far UVC safe disinfection solution of UV light) to treat pathogens is far more likely to depend on the protein aspect of a pathogen, which can have substantially different absorption coefficients, rather than the proven nucleic acid DNA/RNA approach utilizing the absorption peak in the 260 nm to 270 nm wavelength range which has been shown to consistently and predictably inactivate pathogens.
