Plastic crystals can often exhibit a burn-in from the paint. Radium-based paint was banned in the 1960s and all of the paint was phased out a decade later. The easiest way to tell if a watch is radioactive is to pick up a simple Geiger counter. This will tell you definitively if a piece is radioactive.

Can a radium watch hurt you?
A new study’s in on radium dials, and a previously unsuspected danger has been unearthed. It is generally conceded by most reasonable (and hell, probably some unreasonable) individuals, that radiation in excess, like anything else, can do more harm than good.
When did they stop using radium on watches?
By the 1960s the amount of radium used in watch dials was approximately one-hundredth the amount used in the early 1900s; in 1968 it was banned altogether.
Can you still get radium on a watch?
But many of the so-called radium watches are still around today, considered antiques and even prized as collectibles. The watches are likely to emit as much radiation today as they did when they were first manufactured, but experts say that in reality, the risk to wearers is probably low.
How much radium is in a watch dial?
Estimates of the activity of (226)Ra in the watches ranged from 0.063 to 1.063 μCi (2.31 to 39.31 kBq) for pocket watches and from 0.013 to 0.875 μCi (0.46 to 32.38 kBq) for wrist watches.
Are vintage radium watches safe?
What You Can Do. Do not attempt to take apart radium watches or instrument dials. Radioactive antiques are usually not a health risk as long as they are intact and in good condition. Do not use ceramics like antique orange-red Fiestaware or Vaseline glass to hold food or drink.
What color does radium Glow?
green
Yes, from around 1913 to the 1960s, they did contain radium, and they did glow green. But the radium itself did not give off a green glow. The radium was mixed with a chemical called a phosphor (made from silver and zinc sulphide). The radium gave off alpha particles, which hit the atoms in the phosphor.
Do radium dials still glow?
Radium dials usually lose their ability to glow in the dark in a period ranging anywhere from a few years to several decades, but all will cease to glow at some point.
What does radium look like?
Radium is silvery, lustrous, soft, intensely radioactive. It readily oxidizes on exposure to air, turning from almost pure white to black. Radium is luminescent, corrodes in water to form radium hydroxide.
How do you know if something is radioactive?
How do you know when an item contains radioactive material? Sometimes it is as easy as looking for any type of marking or label on the equipment. If you see an item with the radioactive symbol or a label that says radioactive, you should contact your RPO/SPO for verification.
How radioactive are old watches?
Any luminous watch made before 1970 is almost definitely coated in some amount of radium. According to the EPA, radioactive antiques are still highly dangerous and were made more so by safety failures in the painting process: Radium is highly radioactive.
What replaced radium in watches?
Radium dials were produced throughout most of the 20th century before being replaced by safer tritium-based luminous material in the 1970s and finally by non-toxic, non-radioactive strontium aluminate–based photoluminescent material from the middle 1990s.
What color is radium?
silvery white
Radium is a silvery white metal that does not occur free in nature.
Are radium stickers harmful?
Phosphorus Glow in the dark products is perfectly safe for everyday use. There are no radioactive materials of any sort in phosphorus glow in the dark products that are sold on this site. On the other hand, Radium Glow in the dark is extremely toxic and radioactive.
What does radium smell like?
Radium is a naturally-occurring radioactive element that is present in rocks and soil within the earth’s crust. Radium has no smell or taste.
What does radium do to the body?
Exposure to Radium over a period of many years may result in an increased risk of some types of cancer, particularly lung and bone cancer. Higher doses of Radium have been shown to cause effects on the blood (anemia), eyes (cataracts), teeth (broken teeth), and bones (reduced bone growth).
What is radium jaw?
radium jaw (uncountable) A disease, with necrosis of the jaw and bleeding of the gums, caused by the ingestion of radium and its subsequent absorption into the bones.
How do I check my watch lume?
All you need to do is direct the light to the watch for a few seconds and then it will glow brightly. Charging the lume with a UV light is unarguably the most effective way if you need it to glow as strong and bright as it possibly can.
What items contain radium?
Radium-containing pills, pads, solutions, kinds of toothpaste, and devices designed to add radon to drinking water were once commonplace. Some of these devices are relatively harmless, but others contain potentially hazardous levels of radium.
What is the price of radium?
Present price of radium is $25 per milligram, $25,000 per gram, $700,000 per ounce.
Is radium used in any products today?
Most uses of radium have been replaced by other radioactive materials or radiation generating devices. However, radium is still being used today in certain applications, such as industrial radiography.
