once again great video kalle thanks .also superbikes @ assen was fab always great racing @ assen 😊
ah great backgrounds people have…from dangers of X-Ray man on oil rigs you became a watchmaker but still with hidden dangers Alpha, Beta, Gamma🤣🤣🤣
thanks for that niggling back of mind question X-ray
you’re literally my comfort person i love you #nkuwan !
Good information to know
Glow in the dark? Why?
Thanks
Thanks Kalle. Always good to be reminded of safety aspects in our practice.
Thanks Kalle,
When hands comtain radioactive paste and the watch hasn't run for a long time, you will notice a discolloration on the dial in the shape of the hands.
Love the pic of Kalle in his natural habitat! Bro, I had long hair, now I'm over 50 and just happy to have hair. On the plus side, with less hair, less chance of me getting one in the watchworks. 😉
Excelente información, muchas gracias, es un placer escucharte y ver tu trabajo
Excellent advice Kalle thanks my friend.
so you lost the hair because of radiation? mine are gone by themself
The geiger counter is the most important tool for me now. You have to differentiate between opening and just wearing the watch. I witnessed how brutal the dying from lung cancer is, I will not service watches with active radioactive paste in it.
Many thanks for this particular video. I asked about how you deal with this issue in a recent comment, so this content is very well timed (for me, at least).
Thanks Kalle
Excellent and informative and humorous..thanks.
I'm not sure which is worse, old lume or 'wrist cheese' 😂
Ir-192 & Co-60 bring back any memories? RT tech from Houston here. Still crazy to me I picked a channel half the world away and you used to do what I do now.
Hey Kalle, leuke foto's 😅.
Sinds 1 jaar ben ik aan uurwerken aan het sleutelen. Nu heb ik een font 34-21 21 jewel uurwerk. Na wat liefde loopt die weer prima. Wat zijn jouw bevindingen over dit uurwerkje?
Don't be fooled about old radium paint being expended. It may not glow in the dark anymore but the radium hasn't gone away. The half life of Radium is 1600 years ! It's a strong Alpha, Beta and Gamma emitter.
Wow! Very interesting, Kalle! But how do you get rid of those radioactive particles after removing them from the clues, dials, etc.?
There is a wonderful story about the girls that did radium paint of dials. Radium Girls by Kate Moore. Very good historical read.
Radon gas is another product of radium that people need to be aware of.
Hi Kalle, excellent video on radioactive dials. I have done quite a bit of research on this subject and concur with your opinion. Not sure if you know of the Omega Enthusiast on YouTube. He is a watchmaker and deals with vintage watches. He is very knowledgable and has done a really good video on radium dials and backs up his findings with results. Well worth watching. 👍
Net een goede nieuwe geiger counter uit Canada binnen gekregen ct008-f aanradertje… bedankt kalle dit is toch wel belangerijke waar veel mensen niet bij stil staan…
So when I see a watch maker with three arms…I should not hire him?
I want a watch with radium paint for so long now!😅
And I know a lot about radiation so I'm not worried at all.
Those watches are only dangerous to the people who painted them in the factories and people who open up the watch and don't have any idea what they are dealing with.
I would never open a watch if I know for a fact that it has radioactive paint.
I know a lot about radiation but as a hobby… I'm not qualified to work with radioactive materials.
And if you know it has radioactive paint and the crystal breaks…. Never touch anything that is under the crystal!
And it's pretty easy to find out if a watch has radioactive paint.
Just keep it in the dark for a few days and check if it still glows without exposing it to any light.
If it still glows… it's radioactive paint.
Incredibly hairy 😂
I got told by a professional that alot of the radiation will be emitted already.
But like you say, the dust or particle seems a problem. Wondering how approach this now as i'll be working on vintage watches over the next few years…
Anyone can share any tips? Will geiger counters be able to assess the alpha radiation particles?
The problem with the radium dust is that your body treats it as calcium as it's chemical make up is similar and deposits it in your bones. This in turn irradiates you constantly as radium half life is 1200 years or so which can increase your chances of cancer. Bottom line is that, as Kalle said, the proper precautions need to be taken.
You need a geiger counter to measure the radioactivity and all 'affordable' meters only measure gamma using a geiger muller tube.
Wrist watches versus pocket watches is all about the dose. Even wrist watches, very early ones, the radium that was mixed in can be very 'hot' and the dose can be quite high.
Nobody, ever, would put clear varnish on a watch dial. Ever. And if they do? Never take your watch to them. A professional will know how to deal with these things properly and safely without damaging your watch dial.
I once gave a watch to a watchmaker who looked at me questioningly when I asked him, whether he takes in watches with Radium lume for repair. He took it and I think he doesn´t have any safety precautions. Am I right to assume that someone like that, must be really lousy at his profession?
I have over fifty years of old vintage wrist watches—don't do pocket watches—in my junk boxes and I have never tested the radiation level. But, considering the thousands of parts and movements I have I suspect it may be a problem. Time for me to start a serious investigation…
The US NRC has a whole PDF article about radium, its a very good read.
