The paper presents measurements of the breakdown (dielectric strength) and dielectric constant of the
low density polyethylene (LDPE) and high density polyethylene (HDPE) thin sheets, which were irradiated
with a 10 MeV electron beam in the range of 0-470 kGy using a Rhodotron accelerator system. The tests
were performed at temperatures ranging from 20°C to 110°C. Variation of the measured parameters vs.
radiation absorbed dose and temperature were discussed.
