    Default Tritium vials

    Hi
    I was wondering if anybody had tritium vials? And how do they make them?

    Thanks
    Will

    I would have a large collection if the stuff weren't so expensive - tritium is the most expensive matter on Earth per mass. The vials are made by culling the tritium byproduct given off deep within the core of a nuclear reactor, so it's not exactly easy to come by.

    Yep, it's somewhere around 20 000 USD per gram... But you can get tritium vials on the marketplace, B@rt sells them at reasonable prices but they only contain a few micrograms of it.

    Of course, his sales thread is here http://www.cpfmarketplace.com/mp/sho...-part-deux-bis
    Just give him a PM.

    Just curious.. how do you weigh something that is lighter than air? I'd imagine Tritium is sold by unit volume under some specified pressure, rather than weight..

    All gases have the same number of molecules in any volume at STP(same/standard temperature pressure)

    So if you know mass of the molecule, temperature and volume you can calculate the mass.

    Most comparisons use Ci(Curie) which is a measurement of the radioactive energy

    lso be aware the stuff is regulated in many places and you may break the law just having a keychain. Unfortunately the NRC has shut down some USA sellers here and on Ebay. B@rt or farid on CPFMP is the best bet IMHO

    Hello ToyTank. John here from Ont, Canada. I don't know much if anything about this stuff. If it is radio active, why aren't there a lot more government selling / trading restrictions on tritium? Lets face it. Anything that is "made by culling the tritium byproduct given off deep within the core of a nuclear reactor" a substance that glows in the dark for ten years or more can't be good. How dangerous is long term exposure to tritium and in what amounts. Would there be any long term health effects from exposure to an amount of tritium contained in lets say a glowworm key fob trailing aroud in your pocket 24 hours a day? How dangerous really is this stuff?

    Thanks for your time John

    From the last "When Tritium Attacks" thread:

Even if you were standing directly over a freshly broken vial, odds are the gas would be too dispersed for even a single molecule to reach your breathing space. If the vial were in your hand or pocket - again, it's a radioactive gas and not solid or fluid, it would simply float off and away, no more glow from your vial.

    Worst case scenario: You break the vial on a table/desk, then IMMEDIATELY cup your hands around the vial and place your face directly over it and inhale deeply. If this were to happen, you'd receive as much radiation as ...a dental x-ray.

    That's the beauty of the tritium vial design, rather than relying on the radioactive substance itself to glow, it uses a strong phosphor that glows brightly with very little energy, so you can use a remarkably weak source of radioactivity to produce a glow. The beta radiation that comes off of a tritium vial cannot penetrate tissue paper, and can only make it about a quarter inch from the vial in open air before dissipating. It's so weak that even if you were to set a Geiger Counter on its most sensitive setting, then press the probe directly onto the vial, it would not register a reading at all.

    Thank you Empire. When I used the term Ignorant, I was referring to it by definition. : lack of knowledge, education, or awareness. I simply meant that I did not know anything about the subject of tritium.

    I have 2 new geiger counters, perfectly calibrated [one with a mica window] and a whole bunch of tritium vials,

    FACT
    tritium vials do emit low energy gamma radiation in the form of x-rays, but the amount is harmless (lets say low risk)

    tritium beta radiation hits the phosphors, and the deceleration of the particle sometimes emits secondary x-rays (Bremsstrahlung)
    these x-rays DO leave the tritium vial and are detectable, and also can penetrate skin less than 1cm if the skin is pressed right
    up to the vial. the x-rays do not travel more than 1 or 1.5 cm in open air...they are very weak, and there are very few of them

    one or two or 5 trit vials directly laying on my detector tube will increase CPM from background of average 20+- to 25-30
    ten trit vials (1x5mm) might push it to 50CPM. more trits, higher cpm. with 10 small trits and 3 large ones I got a CPM of 100 sustained.

    is this any more risky than standing outdoors in the sun ? nope. but added risk from trits is not zero...people commonly
    get more radiation exposure from the environment than trits will ever do
    ----
    do I carry trits on my keys and carry a trit light everywhere. You bet.

    Do I know for sure if trits emit radiation past the glass vial or not ?
    absolutely, and they do...

    Awesome test, thanks for the data! How does the reading from a trit vial or two compare to a banana?

    I'm wagering the banana will be more radioactive than the tritium vial

    How much? I'm told that many static discharges (eg peeling scotch tape, lightning) have a chance to produce X-rays, but they do not get far before being attenuated in air.

    Lightning X-ray photo tragically has no image of lightning.
    My biggest light-hog is my camera.

    Default Tritium vials safety, something new that may be concerning.

    Hello dear members of the forum.
    As an avid flashlight collector, I have some with tritium vials in them (I am sure you do to...) and I also have some pendants, key chains and even a ring with tritium.
    Until now, I felt very safe, having tritium vials close to my body, because they emit only beta radiation that cannot escape the vial.
    Now I found that the beta radiation is only part of the story. I found out the the vials emit x-ray due to the Bremsstrahlung effect, as you can see in this link:
    https://www.youtube.com/watch?v=O8l0sUfN89A
    Nothing about the danger of the x-ray is mentioned in the Wikipedia page of the tritium vials and I wonder why?
    Clearly, you can see in the video above, that these vials emit x-ray and I wonder if any you can comment about my discovery.
    Thanks :-)

    This topic and tritium vial safety has been discussed previously. Quite a bit over many years.

    Thank you very much for the info. I didn't see this thread before. I read many posts regarding the beta radiation but not about the x-ray.
    Looks like that after all it is not "perfectly safe" as many people think. and not only a broken vial can be dangerous (to a degree of course).

    Actually, from what I have read, it is a stretch to call even a broken vial dangerous. It may give you a tiny dose of radiation...but people get exposed to radiation ALL THE TIME. Background radiation is part of living on planet earth. If you are comfortable going to the beach, there should be no reason to worry about tritium vials. You get a LOT more radiation from the sun than you ever would from tritium vials.

    Since I am not a scientist, I can not make the numbers...
    wearing a 5 large tritium vials (2.25x3) pendant on my neck, only a shirt is separating it from my skin, is as dangerous as walking outdoor?

    Default Re: Tritium vials safety, something new that may be concerning.

    The amount of this effect is something to think about though...

    For example, an ordinary banana might be giving off ~ 800 - 1,000 counts per minute simply because it has potassium, and, potassium has radioactive isotopes that are typically present in trace quantities, etc. The attached video shows a fob pressed against the face of the detector giving ~ 6,000 counts per minute....and a background count under ~ 1,000 cpm.

    So, given a banana being many times larger than a fob (For most fobs at least...), the keychain fob, with NO shielding, would be about as dangerous as putting bananas in your pocket.

    So, while a fob in your pocket might help you find your room keys, the banana in your pocket might help you get someone ELSE's room key.


    The DANGER posed by these two scenarios might be more related to false impressions/STD consequences than radiation.

    Food for thought.

    Thank you TEEJ,
    what about the accumulation effect? these numbers don't add up?
    Let's say, I don't ware the pendant 24/7, take it off at night. 6000x15. that's 90,000 ! What this number means, and how is it measured when you add it to a full year? is this number neglectable? and 5 tritiums pendant is 5 times as much...

    Think of it this way:

    To do DAMAGE, essentially, the radiation has to damage some genetic material, and, that material has to stay unrepaired.

    The higher the dose itself, for any given time, the more likely that is to happen.

    The more times it occurs, the more likely that is to happen.


    BUT, you still have to keep the SCALE of this in mind, or you live in a cave wrapped in Al foil, etc.


    Think of it this way for a moment:

    A banana is about as "radioactive". Your granite counter top in your kitchen can be MORE radioactive sometimes, and so forth.


    If you EAT a banana, the potassium becomes PART OF YOU. It is now used in your bones for example. Every banana you ever ate is, to an extent, still with you...in that regard. That radioactive potassium you EAT is inside your body, against your mucous membranes where there is the least shielding/most sensitive tissue....until the food is broken down, and the calcium, potassium, and so forth, are removed to be used to make YOU.


    No one, to my knowledge at least, has ever shown that a life time of eating bananas and having the potassium from them (Or any other food with potassium), incorporated into your body, has ever caused harm.


    I would therefore be inclined to believe that foods that contain potassium are universally considered to be healthy, and not dangerous. I would NOT condone EATING tritium fobs of course, not even as a light snack, and, you'd simply need to glow to the bathroom afterwards.

    Logically added exposure adds risk. Comparing apples to oranges, bananas to tritium, natural to ionizing is well.... not really a comparison.
