摘要：

Investigations were performed on polyethylene of about 170 mg cm** minus **2 thickness. The equipment used for gamma -irradiation in air was either a **6**0Co source or irradiated fuel elements with dose rates of 0. 1 and 12. 5 kGy h** minus **1, respectively, up to doses of 1000 kGy. For positron lifetime measurements a conventional fast-slow coincidence circuit was used with a time resolution of 350 ps (FWHM) for **2**2Na energy windows. It was possible to describe the distinguishable influence of dose and dose rate by logarithmic functions.
