Far-UVC Krypton Chloride Lamps-Safer DNA Exposure Compared to Sunlight

This study used computer modeling to examine the DNA damage risk from far-UVC light versus sunlight. Results focused on CPD formation (a DNA damage marker) in two climates: Harwell, England, and Thessaloniki, Greece.

  • Key Findings:
    • 10 minutes of sunlight (UV Index 4) caused as much CPD damage as 700 hours of unfiltered far-UVC or 30,000+ hours of filtered far-UVC exposure at the basal skin layer.
    • Sunlight poses a significantly greater DNA damage risk than far-UVC.
