Why the warnings about using radioactive signs and labels responsibly?
The distinctive three-leaved trefoil symbol is an internationally recognised warning sign for the presence of radioactive materials. Misuse of these signs – on discarded boxes or containers, for example – might cause concern and could result in a false alarm or ‘NAIR alert (National Arrangements for Incidents Involving Radioactivity), which you really wouldnt want to be responsible for, or involved in! By all means use them for decoration in your home etc., but they should never be attached to objects or anything in public view that could be mistaken for a container of radioactive materials.
