■1. Information on the inactivating effect of the Covid-19 by ultraviolet light
┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛
The Hiroshima University hospital has clarified the inactivation effect of a new type of coronavirus by ultraviolet light.

★ Points of this research result
The Hiroshima University hospital were the first in the world to clarify the inactivating effect of the new coronavirus by ultraviolet rays with a center wavelength of 222 nm.
Compared to 254 nm wavelength ultraviolet rays, 222 nm wavelength ultraviolet rays are considered to be safer for human eyes and skin, and are expected to be applied to infection control measures against new coronavirus infections using 222 nm ultraviolet rays.
