Know what the WHO has to say about UV sterilization?

BITCH NO ONE IS ASKING ABOUT HANDS

Fuck you, WHO. Fuck you SO HARD.

405 nm light technology for the inactivation of pathogens and its potential role for environmental disinfection and infection control

New Proof-of-Concept in Viral Inactivation: Virucidal Efficacy of 405 nm Light Against Feline Calicivirus as a Model for Norovirus Decontamination

    Antiviral activity was successfully demonstrated with a 4 Log10 (99.99%) reduction in infectivity when suspended in minimal media evident after a dose of 2.8 kJ cm−2. FCV exposed in artificial faeces, artificial saliva, blood plasma and other organically rich media exhibited an equivalent level of inactivation using between 50–85% less dose of the light, indicating enhanced inactivation when the virus is present in organically-rich biologically-relevant media. Further research in this area could aid in the development of 405 nm light technology for effective NoV decontamination within the hospital environment.

The lamp in question is this guy. it cooks 5100mw radiant flux at 405nm. It was held 4cm away from a petri dish. One watt is one joule per second.

100 seconds under a 4W lamp fucking killed everything. This piece of shit is 5.1W and I have it in my garage. And that's not sitting on a surface, that's swimming around in fake fucking cow blood.

Know who uses 405nm light? The orcs-with-tits posse
