Measurements were made of the electric conductivity, penetrability, dielectric losses, and electric resistance of insulation materials exposed to 1.25-Mev gamma radiation at 20 r/sec. The electric conductivity was measured with accuracies from 4% at sigma = 10/sup -12/ to 10/sup -14/ to 40% at sigma = 10/sup -19/ ohm/sup -1/ cm/sup -1/. The dielectric losses were studied at frequencies of 40 to 10, 10, 10, 3 x 10/sup 9/, and 10/sup 10/ c/sec. The order of error for tg delta at 40 to 10/sup 5/ c/sec and 3 x 10/sup 9/ to 10/sup 10/ c/sec was about 10%, for 10/sup 6/ to 10/sup 7/ and 10/sup 9/ to 10/s up 10/ c/ sec and tg delta = 10/sup -4/ the order of error was 30%. The order of error for penetrability was 3%. The measured characteristics of polyethylene and plastic AG-4 are tabulated. (R.V.J.)
