10 "facts"
By: Baron - Mr Red : March 3rd, 2015-10:24
1) Fact - Rolex used to lume their watches with varying amounts of radioactive material. Sometimes a lot. Sometimes very little. Hence today, those watches that received a lot will tend to emit a more, whilst those watches that received virtually none wil...
Excellent post!

Joe, thank you very much for that excellent post! It is very rare these days to find scientific rather than emotional approaches to critical issues determining the value of our watches! Thank you for that!
Thanks Jason.....

....so basically your findings appear fairly similar to mine. Readings of between zero and double-digits with no apparent logic on what does and does not score high radioactivity detection. I am sure others will contribute to this learning database, but f...
Great post !

thanks for the great write up, another reference post on the forum. Unless you use gamma spectrometry, you cannot identify any kind of radioactive element. Especially with a Geiger counter, which was not invented for that purpose by the way. The Geiger co...

Thanks for your comments and opinions. They are always welcome. I can think of one good reason why I would not want to remove the plexi off my radium dials....well, several maybe. First, alpha particles are quite dangerous in terms of biological impact. I...
Well Joe

unfortunately it does show a clear lack of character on the Persons who preach the geiger. Too bad they are not engaging thru constructive dialog on this but instead, they choose to delete the article in VRF. Shame on Them. Iceman
Thanks Iceheller

Thanks for your comments. Very helpful. I have a couple of things to add to what you stated..... There are way to convert GM counter uSv/hr reading to Bq if you know the calibration source radiation material and the efficiency of your GM counter for the p...

......I am still waiting for someone to tell me just how decayed the Radium-226 that was used in the 1950s was. Had it been decaying for 10,000 years prior to being applied by Rolex to their dials....maybe just 5000 years? Maybe it was brand "new" with no...
Hey Iceheller....

.....its good to raise these issues. Here is where we differ..... 1) A specific Rolex reference may have had its dial produced by different dial manufacturers. Rolex used multiple suppliers. Similarly, Rolex used numerous suppliers for the hands on their ...
Conclusion

Well with so many unknown, then more we should use infer statistic to draw a conclusion, well that what scientific community ( forget to mentioned I used to work in one of asia top university for a period of time doing technical work and involved in a han...
Oops.

Forgot to conclude, GM counter can indeed be use to check for the presents of radiation on watches, just like X-Ray can be used to detect fr cancerous mass in the body. But if u want to know the extract type of radiation then u use other instruments, like...
