Re: For Pete's sake
I work in a site where you can't enter if you don't have your badge. I can't enter my office without the badge, nor I can eat at the canteen. If you forget it, the reception will issue you a temporary one on the spot after checking who you are.
You quickly learn how to ensure you always have your badge with you. After all people also take care of their car keys, or they may not be able to get back home. AFAIK medical personnel working where radiations are present must carry a dosimeter.
If needed, plant a chip under the medical personnel skin.... <G>
