- Is your Radioactive watch a Radium watch or a Tritium watch? Here is a cheap flashlight test you can do at home. Concerned about Radium in watches? See how I tested my Radioactive watches to identify dangerous Radium watches and more safe Tritium watches. Below is a very cheap tool you can use at home to do a test I did.
Buy cheap UV Flashlight you can use for this test:

It is more accurate to use a Geiger counter to measure for alpha particles and gamma rays being emitted by the radium. I've found that these glowing lume tests are not always reliable, as the amount of radium (and luminous paint that is being charged up by the radium) is drastically different from one watch to another. For example, my relatives have several early 20th century radium clocks that still glow in the dark, since the amount of radium and luminous paint is much higher. Sometimes the radium burns out all of the luminous paint and sometimes it doesn't.
@user-wv1pj6wh4h Tritium has a half-life of only about 12.5 years, so you are right that it will not light up (on its own) any luminous paint after a couple decades. A flashlight can sometimes briefly get the tritium-based luminous paint to glow, but once the light source is removed the glow should subside quickly.
I have a couple of Rovyvon “tritium” pendants that are hot on my Geiger counter. The few people they have responded to me say that it is not a big deal but many say tritium shouldn’t register on a Geiger counter
It also depends on the paint used and the quality, some of the old radium Rolex watches react similarly to the tritium on this one but dies down a tad quicker. Geigers are your true test
The depletion of the paint is caused by alpha particle induced destruction of crystals of the luminophore. As tritium is a soft beta emitter, the destruction occurs at much smaller scale. Also its activity drops faster. Some watches which contain less radium may have longer afterglow.
The zinc sulfide has been deteriorated by the radium. If you could repaint the watch again it would glow like it was new.
Do Russian made Vostok watches still use radioactive materials? Have you ever checked them out?
Great talk but please reduce your errm count
I know, need to cut it out. Thanks!
Do G shock use radioactive materials?
no
Am i blind or am i not see anything 2:00
