Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?::Can special lightbulbs end the next pandemic before it starts?
A bit of the old Ultraviolence, eh?
I worked for a company that made a UVC light system for sterilization. The amount of safety you have to build in so people wont nuke themselves makes them hard to use.Also, the bulbs we used were delicate and had issues constantly.
Who the hell thought that an NFT festival was a good idea and unprotected UV lights?
Maybe the organisers were exposed to gamma radiation lwhen they thought up the event.
i imagine theres a lot of overlap.
Without bothering to read the article, I look forward to sunburning my retinas like im at a crypto rave.
What if, and hear me out,
What if…
What if… we just ran them when people weren’t in the room? 🤯
Crazy what happens when you can come up with your own thoughts instead of parroting reddit comments ad nauseam.
Lemmy users don’t respond well to reasonable criticism or facts.
Only toxic and stupid comments allowed.
What if… we just ran them when people weren’t in the room?
This is already a thing in many hospitals, and has been used extensively even before covid.
And bleaching all materials in the room. And slowly destroying anything made of paper or plastic or wood.
The article does mention the issue of safety and how to address it actually
To be fair, nobody complained about getting COVID from that event.
Joke aside, looks like they’re using a higher bandwidth of light, 222nm compared to more common 254nm uv for medical uses. It doesn’t penetrate the skin or eyes sufficiently to cause damage.
“X can kill gems! Why don’t we use X everywhere?”
X: Thing that can kill humans too. And/or cause cancer.

Just use sarine FFS, that’ll teach them little invisible bastards
But what if we just inject the bleach? Or what if we just shine the light on the inside?
tbh I wouldn’t mind running some of my stuff through a cleansing by fire ritual once in a while
It worked for Thích Quảng Đức !
Don’t forget bleach!

This is the best summary I could come up with:
Ultraviolet retained a small coterie of enthusiasts over the ensuing decades, focused narrowly on preventing transmission of tuberculosis — which has no reliably effective vaccine for adults — in its remaining hotbeds, like homeless shelters.
The biggest test it received, the Tuberculosis Ultraviolet Shelter Study of 1997-2004, demonstrated that “upper room” UV, in which UV-emitting lamps are placed at least 6.9 feet above the floor where they can disinfect air without harming humans, was safe.
It wasn’t — detective work from scholars including Linsey Marr, Jose-Luis Jimenez, and Katherine Randall in the middle of the pandemic determined that this conclusion was based on a misinterpretation of the Wellses’ research that had somehow persisted for decades in the medical profession.
“This is the most difficult talk I’ve had to give in my career,” Jose-Luis Jimenez, a distinguished professor of chemistry at the University of Colorado, told the audience at the first International Congress on Far-UVC Science and Technology this past June.
But 2020 was also an unusually brutal year for airborne disease: 49,783 Americans died from influenza in 2019, for instance (and none from Covid); 1 percent of that number is about 500 people, which starts to feel comparable to the air pollution cost Jimenez identifies.
Jimenez favors using UV in very high-risk locations, such as hospitals, but worries that construction companies, schools, malls, and the like will seize on the potential of far-UV as an excuse not to invest in proper ventilation and filtration, leaving us with the ugly trade-off he identifies.
The original article contains 4,104 words, the summary contains 252 words. Saved 94%. I’m a bot and I’m open source!
We use uv light stands in the hospital. We will shut down a room and run a uv sanitizer for a bit. It works in some instances but it’s not exactly something you can just leave running all the time. Everyone would probably have a sick tan tho… To go with their skin cancer…
The issue with stuff that kills everything is that… Well it kills everything.
Because it burns you. That’s the answer. It kills your skin cells and eyes the same way it kills the bacteria. Also, it is everywhere, it’s fucking outside. The sun. Fucking stupid. Idiots.
Know what else kills bacteria? Bleach. So get chugging.
So stupid.
Read the article. These problems are addressed.
Pretty counterintuitive that in order to make UV less dangerous for humans, you can make it more ionizing. Anyway, I’d expect problems with degradation/yellowing of plastics, bleaching of everything in range, and massive issues with indoor ozone and some other forms of air pollution
This thread might be the worst example of “I didn’t read the article, but I’ll comment anyway” that I’ve seen.
Why isn’t it everywhere?
because it sounds scary even though it actually isn’t, and people don’t want to read the science, they want to read one headline and give a reactionary uninformed response.
the comments are exactly the same echoes as, “omg mobile phones use microwaves? those things that cook food? omg they must be cooking my brain, GIVING ME CANCER 😱😱😱”
Yeah but ducks shouldn’t do that!!!
(I didn’t even read the headline)
Did anyone actually read the article? The only guy whose question wasn’t already answered by the article was the one about yellowed plastics, lol.
If it kills all the viruses it also kills you lol
The bulbs don’t last very long last time I looked into this for home use
Imagine writing this headline in a universe where daylight exists rofl.
