Abstrakt: | In this paper, the results of EPR measuring of free radicals for two types of polyethylene of ultra high molecular weight: GUR 1020 and GUR 1050 are presented. Samples were irradiated by electron beam energy of 10 MeV and dose 26 kGy a number of times (i = 1, 2, 3, 4, or 6). With the increase of radiation, the amount of free radicals increases as well. In both cases of polyethylene GUR 1020 and GUR 1050, the effect of saturation at the maximum dose of radiation equal 156 kGy was not observed. This proves that both types of material show similar radiation resistance. |
