    Hello,this may have been discussed before(did'nt find anything) but does anyone here know if tritium capsules would freeze and rupture in extended -0 weather? I sometimes have to leave my G27 for extended periods(9 hours +/-) in a lock box under my jeep seat.The past few weeks here we have had a few bitterly cold days and i am worried about damaging the sites.The reason i ask is i'm not sure if the tritium is a solid or liquid and assuming it's a liquid i would think it would have the potential to expand and crack the vial.If anyone has any information on this subject it would be greatly appreciated.Thanks.

    Its 22 Degrees here right no I'm putting the 29 outside now I'll leave it out overnight and let you know in the morning (supposed to be aroud 14-16 out tonight)



    I really am doing this because I kinda wonder too. I always have my G29 with me when I hunt and it gets plum COLD out I haven't had any issues but the gun is usually under a coat and against my body (aside from a layer of under armour between us)
     

  3. No I don't think so. The police use them in sub zero temperatures all the time.
     
  4. Tritium is neither solid nor liquid, it is a GAS. I think you're fine.

    Thank you Captains1911,i had never considered it as a gaseous form.Appreciate the help!

    A room temperature gas turns to a liquid and a solid at a certain temperature:supergrin:

    But yes you should be fine.

    Radioactive decay is not affected by the temps found on Earth.

    For the past 2 years mine has been locked up in a vehicle for 12+hrs a day, 5-6 days a week in Michigan winters. I haven't had a problem yet.
     
  9. So according to you, hydrogen, nitrogen, oxygen, helium, carbon dioxide, carbon monoxide, AIR etc., etc., etc. turns to liquid at room temperature...

  10. Night-sights are glass "lamps", filled with pressurized tritium GAS and cushioned in a bed of silicon rubber to prevent damage from shock.
    Tritium is an isotope of hydrogen, is radioactive with a half-life of about 12.2 yrs. It glows because it is a radioactive gas. You don't have to worry about heat or cold.
    12.2 years from now, your sights will still be 1/2 as bright as they are today.
    24.4 years from now, your sights will still be 1/4 as bright as they are today.
    After 1024 years from now (1/2 to the 10th power), they will still have a dim glow, although you won't be around to see it.
    Here is a link to Trijicon which shows the construction of these lamps.

    p.s. Physics and math can be fun.

    The boiling point of tritium is -415 degrees F. You should be fine as long as your jeep is parked on this planet. BTW its half life is 12.26 years.

    Edit.
    Looks like Sonnytoo beat me to it with the science facts.

    Not always. Some compounds go directly from solid to gas. It's called sublimation. Dry Ice is one example. :tongueout:

    And, as a result, dry ice sights have fallen out of favor. :supergrin:

    If you get it down below -252.8 C, it will change from a gas to a liquid.
     
  18. I thought they filled the vials with Tritiated water. Could be wrong though.
