BTW, there was a good article on watch lume a few months back, in Watchtime I believe. If you happen to BE a lady who wears nail polish, you might already have the stuff! Our Policies Privacy Notice.

I've had mine for 10 years Although health problems in workers applying radium paint to watch and clock dials were noticed in the late s, radium paint continued to be used. If this is the case, then wouldn't tritium paint be kinda like the fake xenon bulbs that claim to be HID, and Tritium vials be the real stuff? My husband was also wanting us to find something old to put in the space rather than buy a new table. If you have any questions or comments, please don't hesitate to contact me via my Contact Me page. When watches were made with radium paint during the first half of the twentieth century there were no international standards governing the use of radioactive substances, these all seem to be modern post s standards governing the use of tritium and promethium compounds. I have bought a radon detector to monitor the levels of activity in the air to make sure that they are below the recommended levels.
For early watches with high levels of radiation from radium paint, sapphire glass can be discounted because it wasn't used until the s. Contact EverGlow Toll Free: The impact of ionising radiation is measured as energy absorbed in body tissue in units of "gray". However, seals deteriorate over time, and watches that were once waterproof may not still be well-sealed. However, radiation is dangerous and it is wise to be cautious. Compounds of deuterium.
Old radium paint is fragile due to radiation damage over the years and it is prone to flaking and disintegrating into small particles and virtually invisible dust, all of which are radioactive. It is difficult to quantify this because the radon detector takes at least 24 hours to settle down, and even opening a door affects the amount of gas in a room which is why I did the test in a sealed box. I decided to remove the hands and dial, working on disposable paper towels and wearing a dust mask. If they are spilled, it could become a major hazmat incident. Nitesiters remain visible in all lighting situations.
