We’ve collected a selection of important scientific articles, explanatory videos, and other research on far-UVC light and its effect on pathogens and people.
This peer-reviewed article from Scientific Reports shows that continuous far-UVC exposure in occupied public locations at the current regulatory exposure limit (~3 mJ/cm2/hour) would result in ~90% viral inactivation in ~8minutes, 95% in ~11minutes, 99% in ~16minutes and 99.9% inactivation in ~25minutes. Thus while staying within current regulatory dose limits, low-dose far-UVC exposure has the potential to safely provide a major reduction in the ambient level of airborne coronaviruses in occupied public locations.Learn More →
In this peer-reviewed article from Scientific Reports, it is shown for the first time that far-UVC efficiently inactivates airborne aerosolized viruses, with a very low dose of 2mJ/cm2 of 222 nm light inactivating >95% of aerosolized H1N1 influenza virus. Continuous very low dose-rate far-UVC light in indoor public locations is a promising, safe and inexpensive tool to reduce the spread of airborne-mediated microbial diseases.Learn More →
This peer-reviewed article investigated the long‐term effects of 222 nm UVC on the skin using highly photocarcinogenic phenotype mice that lack the xeroderma pigmentosum complementation group A (Xpa‐) gene, which is involved in repairing of CPDs. CPDs formation was recognized only in the uppermost layer of epidermis even with a high dose of 222‐nm UVC exposure. No tumours were observed in Xpa‐knockout mice and wild‐type mice by repetitive irradiation with 222 nm UVC, using a protocol which had been shown to produce tumours in Xpa‐knockout mice irradiated with broad‐band UVB. Furthermore, erythema and ear swelling were not observed in both genotype mice following 222 nm UVC exposure. Our data suggest that 222 nm UVC lamps can be safely used for sterilizing human skin as far as the perspective of skin cancer development.Learn More →
This peer-reviewed article evaluated acute corneal damage induced by 222 and 254 nm UV light in albino rats. In the study, no corneal damage was induced by 222 nm UV light, which suggests that 222 nm UV light may not harm rat eyes within the energy range and may be useful for sterilising or preventing infection in the future.Learn More →
In this study, chronic irradiation with 222 nm UVC light was revealed not to induce mutagenic or cytotoxic effects in the epidermis of mice. These results indicated that 222 nm UVC light emitted from the lamp apparatus (or device), which was designed to attenuate harmful light present in wavelengths of more than 230 nm, represents a promising tool for the reduction of SSI incidence in inpatients and hospital staff.Learn More →
This study from UV Medico demonstrates the effectiveness of the UVM 222 EXC on surface contamination. The study helps users determine optimal treatment times and shows to what extent the UVM 222 EXC is able to reduce pathogens, especially at a distance. The researchers who conducted the study were able to determine that even if a room was fully occupied, irradiation for 10 minutes or more during the lunch hour and between meetings when the room was unoccupied could result in a significant bacterial reduction.Learn More →
This study from UV Medico shows the anti-microbial effects of the UV222™ lamp placed in the ceiling of a bar. The researchers who conducted the study were able to demonstrate that a single unit can reduce the number of live bacteria in a bar-setting with more than 100-fold. In general, bacteria are more resilient to exposure with 222nm light than e.g. SARS-CoV-2 virus, along with other viruses, with a minimum of 99%. This could be assumed to reduce the changes of viral spread in a bar-setting significantly.Learn More →
