RE: Radium on Luminous Dial Watches

["Dukelow, James S Jr" <jim.dukelow@PNL.GOV>]

I know that I bought a Tissot swiss watch in Europe in 1962 and wore it for 12

years, until I read the dose rate in a nuke engineering lab course in 1974.  2

mr/hour at the watch crystal face.  My wrist, hand, and left cheek are all fine,

these 27 years later.



Best regards.

Does anyone know approximately how much Ra-226 was present on the face of a

typical radium-dial wrist-watch used during the first half of the 20th

Century?



Thanks....
