Ohio: Goodyear tire and rubber facility, featuring a radiation laboratory for industrial research. Geiger counter is used. Source of radiation is Cobalt 60, held in underwater chamber 17 feet below a radiation test chamber. An aluminum rig is set up in the chamber at the mouth of a shaft from which the Cobalt 60 will rise. Tires are to be tested to see how they will work on atomic powered aircraft. Also bottles. Scientists leave radiation chamber and seal it behind doors marked ‘hazard’. Scientists operate the Cobalt 60 mechanism from a control room. The Cobalt 60 is raised into the room. Scientist’s face can be seen watching the experiment through the protective window. After the samples are irradiated, the Cobalt 60 is lowered back down to bottom of the shaft. Then scientists re enter the room to test samples. They check the tire pressures with a gauge. Two plastic bottles are put into an oven. When the oven door is re opened, the irradiated bottle is intact. The non treated plastic bottle has melted.
