Are watches with radium dials safe?
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.
Is radium still used on watch dials?
Radium dial production peaked in the first decade of the 20th century as radiation poisoning was then unknown to the general population; subsequently, radium dials have largely been replaced by phosphorescent- or occasionally tritium-based light sources.
Can you still buy radium watches?
Radium was eventually banned after scores of dial painters died from cancer and various ghastly ailments. But many of the so-called radium watches are still around today, considered antiques and even prized as collectibles.
How can I tell if I have a radium watch?
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.
When did they stop using radium in watches?
1968
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.
When did Rolex stop using radium?
Rolex stopped using radium in 1963 due to the high risk of cancer that this radioactive substance has. This applied to the people who worked with it daily in the factory. In fact, people did develop cancer from working with applying radium to Rolex’s dials. So Rolex found a different material to use instead of Radium.
When did watches stop using radium?
Radium paint itself was eventually phased out and has not been used in watches since 1968.
Do radium watches 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. A radium dial clock from the 1930s. A key point to bear in mind is this: the dial is still highly radioactive.
How do you dispose of radium clocks?
There isn’t enough radium paint on a watch dial to be of any environmental concern. Just throw it in the trash.
How long will a radium dial glow?

Are old Rolex watches radioactive?
From the 1950s to the late 90s, Rolex used the radioactive material Tritium, which refers to the chemical used on the hands and hour markers of the watches, which causes them to illuminate.
Are radium dial watches a health risk?
Conclusion Our research has confirmed that radium dial watches individually are a modest health risk to wearers. It would seem prudent therefore to apply the ALARA or ALARP principles. Significantly, there is also a risk to amateur collectors from radon gas emitted from the radium.
Where do radium dial watches come from?
The watches tested were produced from the 1920s through the ‘60s, and are a mix of British, Swiss, and American origin. US radium dial painting factory. Read more about “Radium Girls” here.
What is the distribution of radium content in pocket watches?
The radium contents of both sets of watches (pocket and wrist) are closely log normally distributed, with correlation coefficients to cumulative lognormal distributions of better than 0.9 in both cases.
What is the effective dose equivalent of a radium dial?
A phantom experiment using a TLD suggested an effective dose equivalent of 2.2 mSv/y from a 1 μCi (37 kBq) radium dial worn for 16 h/day throughout the year (dose rate 0.375 μSv h − 1 ).
