Radiothermoluminescence (RTL) of the ultra-high-molecular-weight polyethylene (UHMWPE) and nanocomposites obtained on its base via introduction of nanofiller α-SiO2 (aerosil) to its volume is studied. Two relaxation processes (α- and β-relaxations) are observed in these composites, whose maximums of thermoluminescence appear at temperatures 205 and 212 K, correspondingly. Features of the RTL spectra in dependence from the α-SiO2 concentration at the absorbed radiation dose 1∙104 Gr are highlighted.
