It has been shown that radiothennoluminescence (RTL) ofthe crystalline regions ofpolyethylene (PE) irradiated in liquid nitrogen is due to the recombination of charges trapped by defects inside the crystallites. The presence of shallow charge traps (less than 0.15 eV) leads to the appearance of one of the main features of the RTL of PE crystalline regions, which consists in reduction in the RTL intensity over the entire temperature range of 100–300 K during the storage of irradiated samples in liquid nitrogen.
