Helmet Protects + Technician from Contaminated Air Brookhaven National Lab oratory maintains this room at Upton, Long Island, for the decontamination of used equipment. Since the atmos phere may contain particles emitting dangerous rays, pure air is pumped into the worker's helmet. White coveralls, plastic cape, and rubberized gloves protect clothing and skin from "hot" material. Radio active waste goes down the drain into tanks where it is stored until it expends its dangerous energy. The steel and lead "hot pot" transports radioactive liquids. His work finished, this man will check hands and feet with a Geiger counter. Cov eralls go to a special laundry. 0os isTHEHotAEA WHICHc "Fido," a Rolling ieF ouns Ano Pmcssne Geiger Counter, e tO OPERATED BYRETE Sniffs Out:Danger ... 1.. . .Yf swf .. ,, If Brookhaven's "hot" mate e .... ........ rialswere spilled unwittingly, they could endanger the health of workers; small but danger ous amounts might even be tracked into homes. This operator makes a rou tine check of the floor in the "hot" laboratory. Clicks sounding in the ear phones suddenly increase if Fido discovers menacing ra dioactivity. A lead cylinder around the counter's nose screens out natural radiations which might confuse the count. Workbenches, walls, and equipment are checked period ically with other instruments. Workers wear detection de vices that record their expo sures. These and other pre cautions have given atomic energy installations a high safety rating.
