For all of the people who are scared of tritium in those vials, there is aproximately 0.0002 grams of tritium in those vials, even if you break it, it is almost imposible to breath all of those 0.2 milligrams of tritium in your lungs.

Cheaper vials here:

I've ordered from them a few times, and it seems legitimate.

I cannot express in words how cool this is.

A few things about this makes it shifty.
1) Its beta radiation, needing more than some nail polish to block the beta particles
3) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
4) This is technically a weapon if brought onto property which is not yours, so please don't make this and bring it to school
5) It looks sick though when you make it and have !!PROPER!! safety precautions and the vials ARE SECURED BY EPOXY and won't fall out.

1) Beta radiation cannot penetrate the dead layer of skin on your body. Perfectly safe. Tritium has been used in several jewelry applications for ages. Check out Luminox and Reactor watches.
2) Tritium tubes weigh only grams, the nail polish will do just fine in this application, although I would recommend a small amount of clear epoxy on the back side.
3) Really? A weapon? How so? You cannot be harmed by tritium in any way. Otherwise it would be illegal to sell on the open market.

Seriously, calm down. Chernobyl Diaries was a fictional movie, ok? Nothing at all shifty about this ring. In fact, it's one of the coolest rings on thingiverse.

ever heard of a joke?................

Dang! If those vials for this ring costed around 20 dollars... My idea would cost a fortune, but would look awesome. I was going to make slots all around the ring so the vials would wrap all the way around vertically sitting... Goodbye to my Idea.

i might print this and use glow in the dark filament :)

I asked a boffin friend of mine, and he is surprised that these tritium tubes are on sale! They are save enough when encased in resin, you need to do some hefty smashing to break them, but secured with nail varnish!! No.

The gas inside the glass tubes, if inhaled will destroy your internal organs. Cool, but not safe.

It is up to every person to do their own research and decide what they believe to be true and what risks they wish to take in life. I am someone who is paranoid about dangerous chemicals - I don't work with acetone, abs, and avoid heavy metals as much as I can. I never use leaded solder. In my view, this ring is much safer than all of those things. The likelihood of it breaking is low, and if one vial breaks, that is a once off event, and the dose is extremely low, and will exit your body within weeks if any is inhaled. We are exposed to carcinogens and radioactive elements all day every day. We are ourselves radioactive, and cannot live without radioactive elements in our body.

To the best of my ability to research these devices, the gas inside the tube, if inhaled, is very unlikely to do anything.

For whatever it's worth, the tritium was sent to me from the UK in a regular postal envelope, with a little bit of foam around them. They could have been crushed by the postal service, but they are fairly strong. The letter was clearly labeled, and neither royal mail nor australia post appeared to have any issue carrying them.

I will also suggest: drinking water in sufficient quantities will destroy your internal organs. It's all a matter of dose.

That's a little alarmist - the gas inside the tubes if inhaled (in significant quantity) MAY negatively impact your lungs. I am not in the habit of intentionally holding tiny vials of beta-emitters to my nose, breaking, and purposefully inhaling the gasses. If you are though, be warned, that could be dangerous.

What ring size is this? And would it be possible to upload different ring size versions?

You should read the description. The inner diameter of this ring is 17mm. There is no universal worldwide standard for ring sizing, so I leave it as a task for you to translate that diameter in to whatever regional ring sizing system is relevant to you. If you need a larger size you should be able to just scale the ring up in the software you use to prepare objects for print. For smaller sizes, you can edit the source file using blender. If that's too hard, let me know what size you need and i'll add a smaller version.

Awesome design, trying to make this for my son but having a hard time scaling the internal diameter up to 20mm with Blender as I am a Blender noob. Is there a "easy" way to do this or a way to do this in Cura without messing up the Tritium Cuts? Thanks!

unfortunately i kinda sucked at blender when I made this. it's not easy to adjust in a perfect way. since you're making it bigger though, I'd just scale the whole thing in x and y and lock the z. the channels for the tritium vials will become slightly bigger, but I don't think it will matter. Most of what keeps them in place will be the epoxy or whatever you use to seal them in there.

To make an adjustable version I think I'd have to rebuild it from scratch :/

Ok, I understand. I'll try scaling the whole thing, thanks for the reply!

I think you are exaggerating the risk of tritium, especially in such small quantities. Phosphorescent materials don't glow for nearly as long as tritium (hours versus decades), and require special recharging to work. You are exposed to radiation all day every day, especially in cities. It is in the air, it's in our food (via potassium), and ourselves. If your house is made from bricks, they emit radiation. If you share a bed with another person or animal, they are irradiating you too. If the principal is to avoid radioactive things all together, then you will live an extremely impractical life. If the goal is to balance risk against utility, these very small tritium vials are very safe and quite useful.

If anyone needs any tubes, I found a few old depleted Uranium Rods on the side of the road and decided to make a batch. Be warned tho, not only will the ring glow, so will you.

H8ers gonna h8

It's was a joke chook, was hoping being a Sydney girl you might be a bit more accepting of your general banter. I grew up in Forestville :)

Insofar as tritium being safe goes, there's this (yes, I know not everything I read on the web is accurate): http://www.physics.isu.edu/radinf/tritium.htmhttp://www.physics.isu.edu/rad...

Hmm.... Its completely safe, just try not to smash them..... Hmmmm.... Completely safe? I think not.

Mostly because they're really fricking expensive. The radiation dose is similar to smoking like half a cigarette, if you inhale the contents, but that's difficult because the gas is a hydrogen isotope, so it likes to float away quickly out of reach of us mere mortals. I think regular chemical glow sticks would be a bigger public health risk because people crack them open and paint the carcinogenic contents on their skin at parties and stuff. I even got some in my mouth as a kid. Tastes really weird!

this is so cool! I want one i wonder if they will ship to me in (insert USA state here)

Good luck! Let us know if you find a source for tubes in the states?

Import where? Who is they?

gumsh0e said the tritium vials wont import to the USA

Up to you to figure out what you can and cannot legally do where you live. I live in Australia where all this stuff appears to be fine.

Be aware, the tritium vials sold by Mad Nuclear Scientist can not be legally imported to the United States due to our fussy Nuclear Regulatory Commission rules against the "frivolous" use of tritium in toys and novelties. I suspect the same is true for the Etsy product this was inspired by (I would note that although the sale price is expressed in US dollars, the company that sells them is based in Greece). Purchase of certain products like watches and gun sights containing tritium is legal.
Too bad. I would have liked to print one of these myself.

These vials are available on amazon

Tritium illuminated watches are legal in the USA and not considered frivolous. Perhaps a watch repair shop could advise on ways to get small vials from local sources. It's a shame it's still so heavily controlled there. These little tubes are bringing me much more joy than is reasonable!

Well, I can put one on any or all of my guns here in the states if the unit is contained in a weapon sight, and I can buy a watch with vials to illuminate the number positions, but I cannot buy plain vials because the NRC thinks that is "frivolous". I guess you were right. This makes no sense at all. It would take 10,000 of them exploding in a small room to cause any kind of threat. It looks like users who want this in the US may have to resort to the grey market to acquire them (eBay); it doesn't seem like it is enforced here, but you never know. This is a shame, I really want that ring. It is unique and artistic, and I learned a bit about radioactivity in my research about this. Good job!

I also don't think they're that heavily controlled here, I see them on gun sites all the time and on a few watches. Seems strange to me that I couldn't just buy some vials here. I'm ok with them on guns, but hesitated to purchase a watch because of the closer proximity to my body and 24/7 contact, and this ring made me think of that as well, but you're saying its ok as long as the vial doesn't break? Is the radiation weak enough that the thin glass will stop it? I know some radiation (forget types, I think I might be thinking of alpha particles?) sources need to be in the body as the skin is too thick (Po(210) for example) for it to penetrate. They used to put radium in watches if I recall correctly and that proved to be dangerous, but I don't think it was contained in a vial, and the radiation emitted might be different. Not sure.
Anyway I'll post a source if I find some in the US so we can enjoy this unique and really cool ring!

I work in the industy. Tritium is a beta emitter. Beta cannot penetrate the dead outer layer of your skin. You're good to go. The really harmful stuff is neutron radiation. That will penetrate any soft tissue and reacts with Hydrogen atoms (you have 2 each in about 70% of your body). Radium is an generally an alpha emitter which is harmless because a piece of paper will stop alphas, but where it becomes extremely harmful is when it is ingested (think fiesta ware and radium infused water vats; yes, they used to think it had health benefits, and in some ways it does, but that's a much more complicated topic) and because it's such a large particle, it will become lodged somewhere in your lungs or digestive tract and just radiate you and make you sick. Hope this clears up some of your questions.

Bottom line, tritium vials are completely safe. Even if they break, the dose is so low that unless through some freak chance the gas becomes permanently encapsulated in your lungs, you're still fine. Wouldn't recommend swallowing the capsules themselves tho...

Re: Radium - yes, radium is definitely dangerous, and I don't believe glass stops it. Radium outputs different higher energy radiation, which can cause bone cancer among other things. You should never wear radium-containing products.

The tritium gas (radioactive hydrogen) emits only particles which cannot penetrate the human skin. The gas can combine with water and enter the body that way, where it can be a bit of a jerk, with a halflife of 7-14 days depending on the season (sweating more? body will move through water quicker). The amount of gas inside the vial is extremely small, even for large vials. In their unbroken state, the radiation does not penetrate the glass so far as I've been able to tell. It does however cause the release of very weak xrays, through the same mechanism as CRT televisions and fluorescent bulbs. These xrays are not of a level to be concerned about. You could swallow these tubes without issue, if you were careful to make sure they couldn't smash somehow. They'd pass right through with no effect. If you don't worry about the radiation exposure of being in a room with fluorescent lighting, there's not much reason to worry about tritium illuminator vials in their unbroken state.
After reading a bunch on it, if I broke one, I'd feel a lot worse about having wasted ten or twenty dollars than about potential radiation dose. And I'm someone who refuses to work with lead-containing products when working on electronics, because I'm especially paranoid about exposure to dangerous chemicals... Tritium really doesn't concern me much at all.

It's not that heavily controlled. People are freaking without doing researc first. A simple Google search shows many places to purchase them. I've ordered several times to replace the ones in gun sites that have warn out over time and even drilled out 3 dot sites to hold vials.
