claim: far-uvc binds efficiently and safely inactivates airborne human coronaviruses
evidence_1: by contrast, far-uvc light (207-222 nm) efficiently kills pathogens without harm to exposed human cells or tissues.", "based on these results for the beta hcov-oc43 coronavirus, continuous far-uvc exposure in public locations at the currently recommended exposure limit (3 mj/cm2/hour) would result in 99.9% viral inactivation in ~ 25 minutes.")
