I havent participated much in the off-topic fora, but I saw this thread and had to drop in these pictures. My Dad received this ashtray from Applied Health Physics Inc., sometime in the early 60's, possibly late 50's.
Of particular note is the CAUTION RADIOACTIVE MATERIAL label on the back......
It's been sitting on a shelf for 50 plus years....hopefully its not still active!
budman1961 , what is it made of ? , what do you think makes it radioactive , other than the warning sticker ? that is a cool piece , very nice
