BATH
Controlled Cooling and Heating Minus 10° C to Plus 65° C
The cobalt-60 source is a cylindrical aluminum rack in which are mounted 71 0.5inch diameter aluminum tubes. Each tube is loaded with 9 aluminum-clad slugs of cobalt 60, 1 inch long and 0.25 inch in diameter. Ears on the rack permit transferring it to or from the shipping container, under water, by means of a long handled tool
The cobalt-60 source, inside an 8 0 0 0 pound lead shipping container, is ready to be lowered into the tank. It is then transferred, while under water, to the elevator in the tank

The stainless steel hood allows researchers to conduct experiments with the highest degree of safety. Dangerous fumes are carried away by a specially designed ventilating system, while materials that are spilled can be washed away. The monitor checks radiation levels and subsequently detects any contamination. T. C. Gregson, Goodyear physicist who helped design the laboratory, is shown doing an isotopic dilution analysis of a radioactive material
