Still radioactive after all these years...

a 1940's aircraft switch with radium paint, showing about 0.15 mr/hr on my vintage Geiger counter, much of it gamma rays. In the 1920's a radioactive paperweight, the Bioray, was sold legally in the U.S.; from the ad material: "with Bioray on one's desk or at one's bedside one can obtain a steady flow of gamma rays continually, without any fuss or bother..." Yikes.
