Do you know far uv?
Far uv (200-225nm) 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 and eye safe’ is that the damaging radiation is entirely absorbed within the outer, dead, layers of skin and eye and does not reach the inner, live cells; if the radiation were to hit these cells (which happens at longer wavelengths like 254 nm or longer), they would be damaged as a result. An increasing number of studies have been published discussing acute and chronic exposure to Far UV-C, most commonly using optically-filtered Kr-Cl excimer lamps. These studies have investigated the effects of Far UV-C radiation on mice and human tissues 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., 2022, Yamano et al. , 2022; Buonanno et al...
