Radiation Detectors at the Skagway Canada Boarder

Ok, most probably only I find this interesting, on the bus ride back from the boarder, we stop at customs and I “detect” some radiation detectors as we drive through. I work in Physics and Radiation Safety, so this to me is awesome cool. I completely understand if it is not for anyone else. Radiation Nerds in the house, speak up!

The yellow and white panels are the detectors.
