Abstract
An investigation is made of the isothermal luminescence (ITL) and thermoluminescence (TL) from low-density polyethylene which have been gamma-irradiated at 77K. From a comparison of the decay of ITL from samples receiving doses varying from a few kilorads to a megarad, it is concluded that the decay kinetics are basically of first order but with a distribution of rate constants. The influence of post-irradiation annealing at 77K on the subsequent TL glow curves has also been investigated. It is concluded that ITL at 77K is a thermally activated process rather than one relying on electron tunnelling.Keywords
