This keychain works with the radioactivity of Tritium gas. Interesting concept. RATE and SUB :)

  • @gvsfgdf physics major...meaning that deals with physics not really to much into elements and such

  • You can get tritium in the US. I have a luminox watch witch has a tritium dial.

  • @polzowatel watch who you are calling an idiot buddy. I'm a physics major. Not some 2 bit internet junkie troll. And the tritium itself is not capable of glowing in the visible light range.

  • @gvsfgdf its not phosphorus u idiot its tritium itself that glows

  • @gvsfgdf Will you please tell me if ur in the US becasue i wanna know if i can get one.

  • I bought some of these about 5 years ago, and they are way dimmer now. The blue ones, especially, are barely visible even with fully dark-adapted eyes.

    The problem is not the tritium decay, but the use of inferior quality phosphors which degrade with time. This was a big problem on the early radium clock/watch dials. The radium has a thousands of years half-life and is very dangerous, but the phosphors degrade after 10 years and stop glowing, hiding the danger.

  • Very nice keychain but you need to know that radiation exist around keychain.

    Concerning radiation

  • Great to stick in your pocket

  • There are also spherical tritium vials with 100x more tritium hence the light output. I ordered something called "tritium torch", can't wait for it co come in :-)

  • @AtomicEmporium I saw some Sodium Iodide on ebay... you might want to check there, I believe it was a granular 50gram sample around 10$ or so... still pretty affordable. They have a 21 year old min. age limit so I can't get any but I would for sure like to see the results if you decide to go ahead with it.
