A contaminated person would stand in this first shower, fully clothed, and stay there until the Radiation Control Officer told them to proceed. The shower prevented fine irradiated particles like dust from becoming airborne and contaminating the Bunker.

Watch your step as you come through the undressing area. All your wet clothing would get dumped into the chute on the wall. The chute leads to a protected area, where Bunker staff would safely dispose of it.

Keep going and you’ll enter the second shower. This one is for hot water and lots of soap. Anyone entering the Bunker after a nuclear blast would have to scrub hard, but carefully. Radiation can enter the bloodstream through any cut or abrasion. Head, ears, nose, nails, and mouth, all had to be washed thoroughly.

Here you’d be tested again and sent back through if necessary. Once cleared and inside, the officer would give you a gown and paper slippers and then you’d be sent down the hall to the medical centre for a checkup.
