On this forum I had expressed my concerns about the radioactivity emanating from my G-P ref: 7317 Gyromatic. I store most of my small watch collection on cushions in individual wooden boxes with hinged transparent lids that all fit neatly together, twelve...  

And alpha particles were stopped by a sheet of paper, non-penetrative, and the risk was in inhalation or ingestion? How are they even escaping the watch itself?

Perhaps the geiger counter is in need of calibration?

Gamma radiation is emitted by radium 226 in the luminous paint and that is what is detected. Emitted beta radiation is not detected by the Geiger. Alpha is absorbed by the watch casing etc but there is the creation of Radon gas within the watch, which can... 

www.ld-didactic.de Interesting! A lead-lined box is likely sufficient, maybe store it away from where you normally sit. Also, I would strongly advise against licking the hands of the watch. Don't do it!

Here is a link to a long report that may explain answers to my questions but I do not understand the measurement units described with relation to µSv/hour: RADIUM TIMEPIECE DOSE MODELING Prepared by A. J. Boerner, CHP M. A. Buchholz

The thing is that if you are worried about that, you should sell it, certainly on redial it. The watch looses all its interest if you touch its " integrity ", here, the dial. Best, Nicolas

I will continue to store my Gyromatic in its sophegus and not worry!
