US EPA / January 2023 “ASHRAE recommends that homes receive 0.35 air changes per hour but not less than 15 cubic feet of air per minute (cfm) per person as the minimum ventilation rates in residential buildings in order to provide IAQ that is acceptable to human occupants and that minimizes adverse health effects.” Link […]
A New Method of Pasteurization for Food: UV Radiation for Food Safety
![Ultraviolet (UV) irradiation has emerged as a promising technology for food processing under real-world conditions.](https://www.litthinking.com/wp-content/uploads/2023/08/lb-14.jpg)
Chemical Engineering Journal / January, 2023 “The application of ultraviolet (UV) light in the food industry has held great promise for a long time. UVC light (200–280 nm) possesses excellent germicidal properties to inactivate a wide range of microbial pathogens (e.g., bacteria, fungi, yeasts, molds, and viruses).” Link to article.

Photochemistry and Photobiology / January, 2023 “The findings from this study support the long-term safety of long-term chronic exposure to far-UVC radiation, and therefore its potential suitability as a practical anti-microbial approach to reduce airborne viral and bacterial loads in occupied indoor settings.” Link to article.
An Excimer Lamp to Provide Far-UVC Irradiation for Dining-Table Disinfection

Nature Scientific Reports / January, 2023 “By varying the lamp irradiance output, the number and positions of the lamps, the far-UVC irradiation can achieve a 3-log reduction for a dining duration of 5 min. Besides, the far-UVC lamp has a low damage risk to diners when achieving an effective inactivation rate.“ Link to article.
Far-UVC Against E. coli

American Journal of Infection Control / November, 2022 “The present study clearly showed a bactericidal effect of far-UVC on ESBL-producing E. coli. We believe that irradiation with far-UVC may be potentially effective in preventing infection by ESBL-producing E. coli in health care settings.” Link to article.

Far-UVC radiation, defined as ultraviolet (UV) radiation with wavelengths from 200 to 235 nm, is a promising tool to help prevent the spread of disease. The unique advantage of far-UVC technology over traditional UV germicidal irradiation lies in the potential for direct application of far-UVC into occupied spaces since antimicrobial doses of far-UVC are significantly below […]
No Evidence of Induced Skin Cancer or Other Skin Abnormalities after Long-Term (66 week) Chronic Exposure to 222-nm Far-UVC Radiation

Far-UVC radiation, typically defined as 200–235 nm, has similar or greater anti-microbial efficacy compared with conventional 254-nm germicidal radiation. In addition, biophysical considerations of the interaction of far-UVC with tissue, as well as multiple short-term safety studies in animal models and humans, suggest that far-UVC exposure may be safe for skin and eye tissue. Based on […]
Whole Room Air Cleaning for High Bioburden Spaces

Nature Scientific Reports / March, 2022 “For the first time, we show that Far-UVC deployed in a room-sized chamber effectively inactivates aerosolised Staphylococcus aureus. At a room ventilation rate of 3 air-changes-per-hour (ACH), with 5 filtered-sources the steady-state pathogen load was reduced by 98.4% providing an additional 184 equivalent air changes (eACH). “ Link to […]
