Dose distribution in polyethylene irradiated with a 10-MeV electron beam

Radiation modification of the gel content and the complex modulus of plastics was used to determine the depth-dose distribution in a solid polyethylene block irradiated with a 10 MeV electron beam, under typical radiation processing conditions. The results indicate that the accumulated charge has no significant effect on the shape of the dose profile. This suggests that, under certain circumstances, intrinsic ''dosimeters'' could be more appropriate than conventional thin film dosimeters placed inside the material for dose measurements in electrically non-conducting materials.
