Tritium vials new
      #5793954 - 04/12/13 08:35 AM

Anyone know where to get Tritium vials?

Preferably some place that doesn't require paypal...

IF you can get them (there are legal issues as these are strictly regulated items), then these folks might know:

Uh... what are tritium vials and what are they used for?

They have a very small amount of Tritium in them that glow in the dark, without the need for "charging". Often used in firearm and bow sights.

I could get some sights and cut them up, but it would be easier to just get the vials themselves...

Used on wristwatches as well,popular with the military,Marathon are one company that uses them for watches suplied to US and Canadian forces, Traser, Luminox are others,they have a half life of about 10yrs, this stuff is mildly radioactive and as such has the radioactive logo on the watch dial, lots of restrictions on how the stuff is used or shipped,DA.

The glow comes from phosphorescent material in the tube, not the tritium itself. But rather than being "charged" by exposure to visible light as in typical glow-in-the-dark material, this material is continuously charged by the energetic beta-particle that is released when Tritium decays to Helium 3.

Perhaps Shane has worn one-too-many glow-in-the-dark watches?

I wear a Luminox...sadly there's no radioactive logo anywhere on the watch face (wish there was...that would be cool). It does use tritium markers however on the hands and hours. From what I've read online, they do leak a bit of x-ray radiation beyond the watch itself but it's weak. The particle radiation itself is blocked by the watch itself. It's a joy to use at night while at the scope...now more fumbling to press the button like on my old watch!

I have 2 watches by Marathon both of them have a radiation logo. The logos on the Marathons are there so the watch complies with the mil-spec. My son also has a luminox no logo on that one either.

Nice watch Marcus - I have a Marathon SAR as well that has the radiation logo but no tritium vials. The manufacturer made a mistake on that run so it is kind of a rare curiosity. It is still a great watch!

Lots of radiation, no logos or vials though....

The radiation exposure we are talking about from these watches is miniscule - and the tiny bit of energy that *is* released, gets absorbed by the phosphorescent material in the tube, before it ever reaches you anyway.

They do work great at star parties, though:

You could get tritium vial gunsights and pull the vials.

I remembered ordering this for my massive scope from my old hunting rifle. When it came through Canada Customs, the officer in charge left a handwritten note saying this item was exempt from statutes regarding nuclear materials.

It came from Austria and still had Russian lettering on the package and a badly translated guide. In the daylight, it was this thick grayish stuff with a hint of green glow. In the dark, this vial cast enough light to read by a foot away.

It came with a set of incredibly tiny brushes and the guide told you NOT to lick the brushes to shape or damp them.

I also brought a bit to school for a project and put some on a slide to look under microscope with and you could see the individual scintillations

Hopefully the stuff you got was not radium paint, which is completely different than Tritium. Radium paint is hazardous and exposure should be avoided.

Hmm.
I have a Seiko watch with a phosphorescent face that glows in the dark for 4-6 hours after exposure to 10 minutes of sun. I can still read the face at 3am if i bother to put my glasses on to read the hand positions.
No radioactive material, and WAAAAY dimmer than an indiglo luminous dial.
It's worked great for well over 20 years, now.
The hands aren't phosphorescent, so display as dark against a lighter background.

JohnH,

Tritium is a gas. What you have sounds like Radium paint, which is not to be trifled it. Hopefully you have it stored in a well sealed container. In that state it is safe, but if spilled, a bona fide hazmat situation.
