["Tonry, Louie L MAJ EAMC" <Louie.Tonry@se.amedd.army.mil>]

Try USR Optonix Inc.  Kings Highway PO Box 409, Hackettstown, NJ 07840 (201)
850-1500.  They sell phosphorescent pigments for industrial applications.

PS.  This powder makes a great training aid for decontamination exercises.

I purchased zinc sulfide as "Invisible Thief Detection Powder" from
Criminal Research Products, Inc, Conshohocken, PA  19428.  2oz. was
about $40.
