Can Ultraviolet Light Kill Bacteria?

[narcovice]

no bactiria is good never touch your nose mouth eyes and ears with the tips use back hand

[ManicEightBall]

@narcovice

MOST bacteria are good for you, and you would die if they weren't around. Your skin is constantly covered in bacteria that serve a number of functions to keep you healthy.

Washing your hands before touching your eyes, mouth, etc. is probably a good idea because you don't know what kind of bacteria you may have touched, but that's a far cry from saying bacteria are all bad.

[DeimosSaturn]

lol, doesn't UV radiation destroy plastic? deeerrrp

[coliwood]

The biggest source of Ultra Violet light is the Sun: "Sunlight is the best disinfectant". it is amazing how technology just confirms what your grandma has told you for years. Not that you want to "Sun bath" your Smart phone, but it just proves that sunlight does work.

[Xzun009]

what's the purpose of the chat?

[barbalote2]

retard

[adriasummers]

UV isnt that effective... i work in a research lab...alcohol or lysol are both best to disinfect or kill bacteria

[MarkHajdukSplit]

@adriasummers: I suppose but if you poured alcohol over everything then your home would smell like a hobo

[adriasummers]

the uv lights arent that effective... i work in a research lab, its actually better to use alcohol or lysol to disinfect and kill bacteria

[TommyTheT5]

So I could use one of those uv light fake money detectors to sterilise things?

[ohmybentley]

I came home the other night to my wife fucking her sanitizer wand!

[Lotum4n]

No reason to wipe your asshole anymore just pull out the wand and BAM!! your done .

[NaRUtoRoCKz4EVEA]

But then you have all that shitty brown gunk all over your ass...

[boredman443]

@NaRUtoRoCKz4EVEA But no bacteria!

[ohmybentley]

That is a good one! Made my bad day better.Had a great laugh,thanks

[zomgbbqwth]

limited exposure to UVA / UVB is okay cos they are used in the treatment of skin problems like psoriasis~ prolonged treatment in a single sitting will give sunburn though~

[jojo808]

* UV-A = 315 to 400 nm. 345 to 400 nm = used for "Black light" effects. 315 to 345 nm = are used for suntanning (some sun lamps also generate UV-B) * UV-B = 280 to 315 nanometers. Hazardous! Largely responsible for sunburn. * UV-C = 200 to 280 nm. Dangerous! Used to kill germs. * Vacuum Ultraviolet - 10 to 200 nm

[asseeninYOURDREAMS]

i thought UV light was outside the visible spectrum... wait yes it is !!

[sparrowshead]

What a bunch of fucking cock.

[Meeshee57]

I would imagine people would associate exposure to UV lights with harmful UV rays from the Sun because they have the same name...why are people so blind?

[nightshot103]

bacteria is nothing compared to the Mercury and Ozone from those UV lamps.

Geez... mercury and ozone from the UV lamps are way more dangerous thatn the bacteria that you've been living with without any problems so far. You might get sick and call in sick or go to the toilet more often (probably once every five years) with bacteria. If you experience mercury or ozone, you will never be the same again, ever. Bacteria is your friend if one of those bulbs ever break or ozone is absorbed.

[nightshot103]

Some UV-C devices emit -- ozone. And that's toxic.

[psyfertech]

isnt that basicaly a black light?

[deathkiller5093]

it IS a black light

[psyfertech]

well my room must be completely germ free because i have a black light on my wall

[1vh1]

A black light is infa-red but UV is ultra violet. They are opposite actually.

[psyfertech]

oh awite, thanks for clarifying that because all this time i was thinkin my black light above my desk was keeping things clean

[nightshot103]

psyfertech, your black light gave the bacteria a shower. Now your bacterias are clean.

[lipevolcom2]

why dont you buy one big like party lamp, leave for 30min. i think will works tha same!save your time.

[lipevolcom2]

well UVA is capable of causing damage to collagen fibers and destroying vitamin A in skin.

[juthjub]

This is not light - we can't see it. It's ultraviolet radiation.

[OENP1576]

it is ligth

its just invisible to human eyes

[juthjub]

At least in Germany a physcist would regard this as wrong. It's simply electromagnetic radiation. Also not "Röntgen light" but "Röntgen radiation". What your mobile phone emmits could be called "light", but no one would do that.

[OENP1576]

who cares that people dont call it light. its is.

[juthjub]

Well sure, in the end it doesn't matter what people here (youtube) think. Physicists don't call these radiation light. The german wikipedia even explicitly mentions that UV radiation is not light. I should update the english version as well I guess.

[alwinovich]

so if you go a little further in the spectrum you get x-ray ang gamma ligt?

no, everything is radiation

we just gave what we can see (red-violet) the name light

[chimerademonninja]

It's not number of bacteria that counts. it's what KIND that would count. And of you want less HARMFUL bacteria, then use some disinfectant cleaner to tidy up a room and wash your hands. It's cheaper than a 80$ wand, and it'll last longer too.

[Snatchier]

Cheaper Option = Was your hands :D

[kingbleah]

is there a uv light i can shove up my jap eye?

you see i pork women of a easy nature!

[bryancmcguire]

the uv light to kill bacteria does work cause this technology has been used in aquariums for years.

[runie360]

could i use this on my contacts? i bet they are crawling with bacteria

[guspaza]

pirello do u rely on donations from fans 2 survive

[BamCky5]

Today i went to marine world and there was a machine that super charged cell phones in 15 mins.

It used a UV light to dis-infect your CELL

[mindyourowndamnself]

I bought this a while back. It was a waste of money. The damn thing broke after 3 days. Not a very durable product.

[GmanL18P]

[modoZaffa]

It would be good for peoples having chemotherapy (because your immune system is down)

[KV123HaV]

[runie360]
