Note that this can’t be used as a proper warning sign as produced in black/white – ANSI regulation (I think) says that the trefoil should be either magenta or black on a yellow background.

@hexmonkey, this iron-on skill badge is not meant to be used an “official” radiation sign
do you think we need an specific official note about this? if so, please assist us with the text and we’ll add it.
thanks!

Just for clarity… this is an “expose to light then it glows” type of thing? No tritium or anything clever in there?
I like the badge, but I don’t want to set off any monitors or alarms at the workspace…
