Article-I.D.: lanl-a.216 Posted: Wed Feb 2 12:40:10 1983 Received: Thu Feb 3 07:03:36 1983 References: dciem.164 I read recently (I don't recall where) that some manufacturers were irradiating gem-stones (perhaps synthetic ones) to change or control their color. I no longer remember the details of the article but it seems that jewelry was turning up with significant amounts of residual radioactivity. Sorry I can't remember where I read it; perhaps some- one else can. Charlie Sorsby
