Radioisotope Tagger Spray
Easy, tough to detect tagging method
This is a small spray canister filled with a (supposedly) harmless radioactive isotope. The isotope is sprayed onto a target, who can then be followed with a geiger counter or other hand-held radiation detector. It can also be used as a practical joke in radiation-sensitive habitats, although Vac-Workers tend to view this type of prank as less than funny. Radiation absorption from the tagger is negligible — less than your average x-ray. Spray is colorless and odorless, but incidentally, tastes terrible.
