- Аннотация: The dose dependence for the intensity of all radiothermoluminescence peaks of polyethylene crystalline regions has been studied in the dose (D) range of 1.3-30 kGy. The initial portion of the dose dependence curve at doses below 5 kGy has the same pattern for all the peaks; the first derivative is dI/dD > 0 at D = 0 and only decreases with the dose. This type of the dependence suggests that charge traps present in the polymer (in intracrystalline regions) at low doses have existed before irradiation. These traps can be reg- ular segments of polymer chains in the crystalline regions. As the dose increases, radiation-induced traps appear and the dose dependence curves for peak intensities become dissimilar. Some of them show a decrease in intensity with the dose, others reach a limiting value and further do not vary in intensity, and the third ones display a permanent intensity rise.
