Q&A

Is far UV (200 – 225 nm) a promising disinfection technique to address COVID-19 and other pathogen disinfection?

Yes, but as with all UV-C solutions we need accurate inactivation (dose) response curves to determine the UV exposure (UV dose) required for the desired level of disinfection. Based on existing literature it is expected that far UV-C will be effective in inactivating SARS-CoV-2 given sufficient UV exposure.

Is far UV (200 – 225 nm) 'skin safe'

Perhaps, but more research is required.

Far UV-C is high-energy radiation which can directly damage DNA and key organic molecules such as proteins. The biophysical basis for the claims that far UV-C is ‘skin safe’ is that the damaging radiation is entirely absorbed within the outer, dead, layers of skin and does not reach the inner, live, cells; if the radiation were to hit these cells, they would be damaged as a result. A number of studies have been published discussing acute and chronic exposure to far UV-C, most commonly using Kr-Cl excimer lamps. These studies have investigated the effect of far UV-C radiation on mice by measuring key chemical and physical changes known to indicate damage from UV-C exposure. It was found that these same damage indicators were not observed under far UV-C irradiation. (Yamano et al. , 2020; Buonanno et al., 2017; Narita et al., 2018) However, these studies only considered known damage indicators, and ‘longitudinal studies’ investigating negative impacts from unknown side effects have not been conducted.

Additionally, the exposure of humans to ultraviolet radiation is the subject of numerous regulations and standards worldwide: 2006/25/EC (Europe), ACGIH 2008 TLVs and BEIs (USA), and IEC 64271 (CB Scheme, global) all employ an actinic UV hazard curve which lists far UV-C as harmful, though at a weighting of 10-30% of that at the conventional UVGI wavelength of 254 nm. These standards therefore define an upper limit to how much far UV light the human body can be exposed to. This would then need to be compared to the dose that is required for the purpose for which the far UV device was designed.

Does far UV (200 – 225 nm) generate ozone?

From a photochemical perspective, yes.

The Chapman cycle (Chapman, 1930) describes the counteractive processes of ozone formation and degradation from the interaction of light with molecular oxygen (O2) and ozone(O3). The rate of generation of ozone by far UV-C (known as the Herzberg continuum in atmospheric science) outweighs the rate of its degradation; the tipping point at which this generation/degradation balance flips is ~242 – 243 nm. (Andrew et al., 2003; Santos, Burini, and Wang, 2012), Far UVC (200-225 nm) only generates ozone in the upper atmosphere, where path lengths are very long. In a normal laboratory setting, ozone would not be generated because oxygen (O2) is a very weak absorber in the far UVC region.

As with any process, the risk of such hazards should be assessed on an application-by-application basis. A low power lamp operated in a well-ventilated area may not generate a measurable ozone concentration; a high-power system in an enclosed space may constitute a substantial risk.

For more information, or if you are at all uncertain, please contact your vendor for guidance and apply suitable risk management procedures.
