Because it is very dangerous and people will absolutely let their toddler play next to the lamp. This is why it’s basically only used in places like hospitals where access can be controlled.

I could see UV light also causing plastics to oxidize and become brittle much faster, because they might not be made for that kind of exposure. So using UV light might mean having to replace a lot of plastic things too.

~~Because that is specifically UV-C and it’s harmful to humans too. ~~

Correction: the article is about even smaller wavelength UV which is not as harmful to humans, my bad.

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!

I’d like to know which 12 users upvoted this so that I can block them all.

An actually halfway decent idea might be adding a strong UV light inside the washing machine or dryer to kill germs. Modern eco methords with 30-40 C° just dont kill the germs effectively. You’d need to wash your clothes at last at 60C° which most clothes (especially sports wear) cant handle anymore. Or just dry them on the outside where we also have a Strong UV source aka. The sun.

This thread might be the worst example of “I didn’t read the article, but I’ll comment anyway” that I’ve seen.

can it kill Tardigrades though?

Because disease walks around as a person and is all the government, police, and banks. Even the jury and consumers here in fast food land, why does no one kill them all and live here. There’s natural food, processed food, jobs, cigarettes, booze, pharmacies, clothing, internet, addresses, electronic stores, knock off stores, bong stores, strip clubs, casinos, and now there’s weed stores. Hospitals what do you mean Japan was like a hospital itself. All anyone did was health stuff preparing for sexual things, and some drug use, but cigarette smoking ruined it. They got that mad about it, and probably alcohol, someone must have faked drug laws existing. Somehow there’s some election system or court that ruins it all. Oh well we all behave and lay in bed like we were supposed to with these TVs

Oh yes and there’s disease added to the food/drinks to brainwash everyone into the parasite economics thing that’s them stealing and embezzling everything and acting with it. But nothing could go on without sanitation or narcotic use, these things wanted occupy someone’s brain and seek attention 24 hours a day in the same house as them.

We’d have to starve ourself while working or finding a job but everyone was self employed, celebrities, and or business owners, stock holders. Maybe shareholders didn’t have these issues. There may have been uv c light bulbs in public schools or outdoor street posts which is why they worked so well at pulling everyone’s mind out of disease banking systems, where the disease didn’t even start it. They were just on the money as in a virus or bacteria physically on it, and they were on cards that come in the mail with that as a way to track you. Seems terrible but it for sure ended identity theft and credit card fraud.

This is why. https://www.theverge.com/2023/11/6/23948464/bored-ape-nft-event-eye-injury-sunburn-uv-exposure

If it kills all the viruses it also kills you lol

Well there use to only be disease below the grass because chlorine was the ozone layer and god publicly added it to the earths atmosphere to change the way life was with the population. Disease was also something different that was added. So how does god do this implementing thing with all these conspiracies going on with economics. This was just his world, everything could have been a hamster in a glass box or cage. The natural world or religious world did not have to exist. Things like radiation change everything and same with animals turning, changing, evolving, or magically turning into people. At one point it was weirder than Skyrim and mid evil and everyone was naked within the last 30 years drinking bacteria infested well water. Wells were no good without filtration or heating, but it’s not that bad. Wells are usually all the way to bedrock but may lack ions from moving water like rapids or waterfalls.

To produce uv radiation you can use chlorine, iodine (heating it to 250 or higher will form a gas and emit radiation, it feels wonderful, condense back into metal when it cools), bromine, maybe even other things.

That’s what hydrogen iodine gas is for, but hasn’t been done yet, or they mix it with plastic with everything becoming LED, basically you can chlorinate or attach whatever element you choose, to the plastic molecules as bonds and then melt it down to form the LED bulbs with a filament. But closer to the filament is better seeing how the bulb itself only gets to 150 maybe 200 degrees if left on for long periods of time.

Mercury may not actually produce ultraviolet radiation at all but it could emit some type of rays.

Uv c is just higher strength uv b, there is more chlorine in the bulb or it is heated to a higher temperature. The actual light itself as in photons or electrons don’t matter besides heat that is produced by the filament.

You can also heat the events without producing light and uv radiation is emitted. If you get hit with high enough strength you can turn entirely black over a few days or weeks, even if it’s just for a few seconds. It’s called evolution.

And that’s all Japan cares about first, is sanitation, or at all, sanitation makes everyone feel good but cleaning and eating large amounts did t always go on, there was less poop and people and animals usually visit or live by waves and moving water.

Because the spectrum required (UV-C) to do so is harmful to humans and the environment. Putting it EVERYWHERE would cause all kinds of problems.

Oof, ultraviolet light. This makes me flashback to April 2020, shortly after the U.S. shutdown for the Coronavirus pandemic.

If you have 1:57 minutes of free time, watch this video of former President Donald Trump addressing the nation on the response to the novel coronavirus.

Warning: If you experience second-hand embarassment, try not to watch Dr. Birx in the background squirm in her seat as she sits through the idiot rambling of the orange man. Immediately after this press conference, corporations and media companies pushed out critical warnings to Americans to not drink or inject disinfectants like bleach.

You really dont want to live in a sterile environment, you actually need some stimulation to your immune and other bodily systems. Most body stuff is like muscles including the immune system - when you regularly over load and stress them, thats the impulse to stimulate growth and evolving.
