Besides being somewhat dim, most keychain lights have batteries that only last a couple months before needing to be replaced—which often never happens since nobody has watch batteries lying around. But what if you could have this Mini Tritium Keychain, which lasts about 10 years without needing to be replaced? If you're worried that keeping something radioactive in your pocket next to your gonads is a bad idea, keep in mind that the particles emitted are supposedly so weak they don't even penetrate your skin. Also keep in mind that science has been wrong about stuff before. [DealExtreme via Gear Diary via Oh Gizmo]

No thanks. I don't want my junk glowing in the dark.
I think I kinda want one.
-and one for my wife, because she can't kill me if I hand her one of her own, right?
@EBone: I was gonna make a snarky remark about anyone else but you wanting to find it in the dark, but I'm not gonna because I'm a NICE GUY! :D
Is it supposed to look like a Green Lantern ring?
I suppose the radioactivity is just another fun coffee table discussion waiting to happen, provided the hair on your junk does not fall out.
Some of the pictures make it look like it barely glows... Am I the only one who thinks this is just that glow in the dark stuff you get from sticking it in the light for a while?
Ow! My Sperm!
Links to the brand (nite) thats been around a couple of years.

Got one on my keyring, it´s great if you lose it in snow or grass, also have a couple of other on other important stuff.
I also have a traser watch with tritium it´s just great with that perfect glow.
And other products with tritum in is the ACOG scopes which loads of military branches use.
And the half-life of tritium is about 12 years, so in 12 years the glow "power" will be about the half as well.
@EBone and Monty: Men, men! Once upon a time these precious parts of our bodies were considered treasure! Jewels! Family Jewels! Have we fallen so far that we denigrate it so easily, calling it "junk" as though it belonged in a gutter?
No kind sirs. Take pride in your "junk." Lift it out of the gutter with the other "junk" and lift it back up to its rightful place!
Well, Beta radiaiton can't penetrate skin so I doubt anything is even escaping the plastic that encapsulates the tritium. (Except photons)
Still, I do wonder what happens when you run tricorde.... i mean Geiger counter over it. Could mean hours of fun at the airport if the TSA weenies go all JoJo the Indian Boy over it.
@Stalhandske: I was going to say the same thing; this material has been used in scopes for years.
@92BuickLeSabre: If someone else waves their precious jewels in front of your face, you may be inclined to refer to it as junk :P
I'm not too worried about my sperm. Children are the blight of humanity anyway.
I just ordered a couple.
Hard to resist shit like this.
Kinda why I hang here. :)
@Kaiser-Machead: Youth is completely wasted on 'em. ;)
I wonder if anyone at the company actually keeps these in their pockets and are practicing what they preach.....
I think I'm OK having to relace a $3.00 watch battery VS having my nuts & bolts fall off!
WARNING: May Adversely affect persons originating from Krypton. Do not Use in Conjunction with Yellow Sun.
@Kaiser-Machead:
Yeah pregnancy is the #1 worst STD.
Just finished my radioactivity training a couple weeks ago. Safe unless broken and then eaten.
@av8thor: Won't penetrate the glass window of a Geiger counter. Have to do a swab test and read in a scintillation counter.
The problem with this is that Dealextreme sucks.
They are slow and the crap they sell is crap.
There are other versions of these which are much better.
BTW Tritium is pretty harmless in these smal quantities.
The radiation is very weak. so weak it doesn't even go through the glass envelope the gas is contained in let alone the plastic case the little glass envelope is held in.
There is NO danger in this as a keychain.
In general these are a fantastic idea. Like when you drop your keys at the movie theatre. they are easy to find due to the tritium marker.
Again DX sucks.
Yaesumofo
These things have been around for years and years and even longer as indicators in watches. It's safe (unless ingested as noted by the fellow above).
I have had generally good experiences with DX, actually. Some stuff is crap, just like everywhere else. They are pretty upfront with their shipping times and they do actually respond to email. Better than some vendors stateside, in my opinion.
@nutbastard:
But you can't get abortions for herpes. I would say its the second worst.
I bought like 10 of these to attach to my mooninite light brite set, now we'll have a real panic.
I dont want to have a glo"stick" ;-)
@Kaiser-Machead:
two demerits for that blight on humanity remark
@Marty
" provided the hair on your junk does not fall out."
You say that like it's a bad thing.
@The Lab:
Try getting that through the TSA
@yaesumofo: My first order with 'em, so I guess we'll see.
WAY late gizmodo! Dealextreme has been selling these type of key chains for a very long time.
Tritium has been used for many, many, many, many years and it's very safe. When I was in the military, Tritium was in the compasses. It's also used in gun sites. ...so far, no adverse *coughs* reactions *coughs*.
I'd get one of these but I really like not getting a body cavity search when I cross the US/Canada boarder which I do often.
Altho I may grow to like it, you never know.
I bought a green glowring about 2 years ago. Lost my keys twice but found them with this thing. A lot harder to find in daylight though.
Not enough light to light your hand though. All you wimpies out there, your junk will be fine. Your tampons might glow though.
Just for kicks..you may want to know that these are illegal in many countries for the radioactive content - including Denmark, also the compass and fishing lures that contain this.
@PynkFloydd:
Yes what he said. Radium (or whatever they used to use to make things glow back in the day) = dangerous.
Tritium = not so much. You could literally ingest the material inside this small tube and you'd be exposed to maybe half as much as you get during an x-ray.
Your junk is not going to fall off. Unless your name is Spitzer. His will fall off for a different reason. Unless singing myspace callgirls are radioactive...Maybe Tom should post a warning.
no no and know if some guy breaks into my house i don't want them to find keys to my car easily.
No offense, but where have you been? These have been available since 2002 and even earlier. The first variants came in 7 different colors and are now only available in 3. Do a search for "nite glowring" on google for more results.
due, my balls already glow in the dark
For you cowards that thinks this radiation, don´t make any airline travels without a suit made out of lead...
The amount of radiation on a round-trip cross-country
from New York to Los Angeles and back would expose you for about 3 mrem cosmic radiation... Think again, lol.
@PynkFloydd: Yes, because we know if the military uses it, it MUST be safe. Like all those guys standing in a foxhole in the 1950s just outside Yucca Flats...
I know, it's safe. I just like commenting about my junk.
@EaGle1337: duh, they will find your keys anyway.
the keyring is safe, but they used (is?) restrictions on there export from the UK as Tritium is a fuel for use in nuclear weapon warheads.
but you would need a few thousand keyrings for that ;)
How long before somebody brands this with the Simpsons logo.
Hm, I was under the impression these were not allowed in the states... at least last time I checked.
Man, if the TSA has a fit about nipple rings, I can't imagine what would happen if you traveled with this.
i got one of these a few years back. i don't know why but my testicles are grapefruit size now.
Wow $10 each! I bought a whole bunch of these tritium keychains off of ebay about 4 years ago for about $20 total, shipped from Singapore, even.
The tritium gas is an isotope of hydrogen and sealed in a little borosilicate glass (ie Pyrex) vial that is coated on the inside with a phosphor. The phosphor absorbs all of the beta radiation and gives off light. The color and brightness depends on the particular phosphor used. I keep a yellow one on my keyring, but they come in about 10 different colors.
It's bright enough to see glowing through a jeans pocket in pitch black and you can read by it in a pinch. Bright it is not but considering that it will glow like that for a good 10 years or so it's still not bad.
One time my wife dropped hers and the plastic housing came open and the vial came out -- fortunately it was not broken and I superglued it back together.
@StarWhores: It would be very easy to get this through TSA as they can't detect it. Furthermore, I have been traveling for a couple years now wearing a shirt that says "army" in arabic. You'd think that'd get me stopped but it hasn't raised an eyebrow. Did I mention I'm white?
sweet mini-WMDs
@The Lab: The army is a nice touch, but I have one that says jihad I use specifically for flying because I want people in the air to know who not to take hostage.
Cool, fun look find and ball shaver!
@DeadWriter: you sure, i tend to hide mine i can't find them in under 20 minutes...
They've been using tritium in watches for years...in fact last time I checked my dive watch hadn't eaten through my wrist yet...Besides glow in the dark junk might be a good conversation starter :-P
@portugue: Wrong, but very funny. Hope you have a credit in the karma bank to offset the t-shirt. :)
I seem to recall reading somewhere that these were illegal to import into the US. Here are the googlez:
[wiki.answers.com]
Tritium devices can be purchased in the UK and Australia, but are illegal for import to the United States, however they are available in the US as gunsights and for military applications.
[outdoors-magazine.com]
Beta lights (tritium filled glass tubes) haven't been available in the US and are currently illegal for import due to NRC regulations.
I see a good market potential in these being gifts from X-Wives and X-Girlfriends. She always said she hoped your "junk" fell off, and now she can make her dream a reality.
@WEGGLES90:
Woo! Futurama reference FTW!
Terrorists are buying these, swallowing them along with some Dulcolax, and then 24 hours later visiting public restrooms....
Dirty Bombs! Death to America!
plasma sperm
I've had one of these on my key chain for years now, and have sired 2 kids during that period. My children's super powers have yet to reveal themselves, but they (the kids) are super smart and wonderfully cute, and the glow stick has enabled me to find my keys on more than one occasion, so I would say it has been a great purchase.
Isn't tritium illegal in the US because of it's dual-use nature?
John Banner here.
Don't make me angry. You wouldn't like me when I'm angry...
