The temperature and frequency characteristics of dielectric penetrabillty and angle of dielectric losses in polyethylene, fluoroplastic-4, and product-10 (mixture of polystyrene and vinyl naphthalene) were studied before and after exposure to gamma rays at 400 to 1200 r/min to a total dosage of 2000 to 100,000 r. The frequency dependence of the angle of losses and dielectric penetrability are almost unchanged at 50,000 r, while at 10r Hertz frequency and 100,000 r the angle of losses is slihtly larger for fluoroplastic-4 but unchanged for polyethylene and product-10. The angle of loss exhibits the same independence of irradiation at various temperatures. The angle of loss and dielectric penetrability was plotted for vitritextolite, resins, and paliomide-68. It was found that in most organic sollds the angle of loss due to irradiation increased at low frequencies and decreased with rising frequencies. It is postulated that the variations of the angles of loss in organic dielectrics are determined by the mechanism of dielectric penetrability. (R.V.J.)
