Spurious LiF light emission - contaminants

["Sandy Perle" <sandyfl@ix.netcom.com>]

I am interested in anyone's experiences with spurious light emissions 
given off while heating LiF chips that have been environmentally 
exposed to soaps. Specifically, finger rings worn by technicians and 
washing their hands with surgical soaps, such as Cyolex (generic 
soaps as well). I am familiar with light emissions given off due to 
talcum powders etc, but not too familiar with the effects of exposure 
to soapy film residue on the teflon coating.

Any information regarding your experiences would be appreciated.

Regards,
