Silicone-insulated motor exposed to radiation source

A new field of practical nuclear research was opened recently when, for the first time, a silicone-insulated motor was deliberately exposed to a radioactive source. Culminating over a year´s study of radiation effects on the physical and electrical properties of individual silicone materials, the motor test leads off investigations into the radiation effects on complete electrical insulating systems made by the Dow Corning Corporation, Midland, Mich.
