ESR imaging of alanine dosimeter annealed under thermal gradient

An ESR image has been measured for an irradiated alanine dosimeter annealed under a thermal gradient. An Arrhenius plot of the lifetime obtained from each pixel of the image gave apparent annealing parameters: the activation energy, E = 0.5 ± 0.3 eV and the preexponential frequency factor, νo = 4 × 102 Hz.
