Protection equipment against radiation. 1 is a dosimeter, an instrument which measures radiation exposure, 2 is the mask to purify air. This suit (3) is made of PVC, has a zip fastener which goes from base of stomach to top of head cover. 4 is a thermo luminescent dosimeter which detects gamma radiation and neutrons. The boots (5) are made of thin plastic and dressed over the shoes. Are conditioned and disposed after use.

Radiation suit

Low radiation waste, like plastic boots, are stored in this type of barrel.
