Dear Cecil and loyal compadres,
in responce to a question posted at http://www.straightdope.com/classics/a990430a.html
on radioactive glow, I believe Cecil neglected to state that radioactive substances, specifically uranium, glows when a blacklight is shown upon them. Back in the 1950’s and 60s’, I belive the way to identify uranium would be to hold up a special blacklight to the uranium, which would in turn glow. Please respond.

Lots of things glow, or flouresce when “black light” shines on them. Including many creepie crawlies, like scorpions. During the uranium rage of the late '40’s and early '50’s, all kinds of people were running around the hills at night shining their “black lights” on things. The “black light” manufacturers did well, but I never heard of any of the prospectors getting much out of it. Except mayber exercise.
Welcome to the SDMB, gogabego. Thank you for including a link to the column. It is much appreciated.
Since this is a comment on one of Cecil’s columns, I’ll move this thread to the Comments on Cecil’s Columns forum.

This is true. In fact, manufacturers of dentures used to mix small amounts of uranium into the ceramic material they used, so that the dentures would mimic the flourescence of natural teeth.
Let’s see how many of Cecil’s columns we can drag into one thread. Is uranium added to false teeth to give them a natural glow?
By the way, in that column, Cecil says the fluorescence of uranium has nothing to do with its radioactivity.
Mmmm… bwhat is it in white fabrics that flouresces? It gllows pruurple.
