✦ Synopsis

Ultrasonic absorption measurements were made at 3.14 MHz on poly( methyl methacrylate) as a function of temperature and after various doses of y-irradiation. The measurements showed a relaxation phenomenon. The activation energy of the various doses was determined and the smallest doses that affected the specimen was found to be 4 Mrad.
