Abstract

The kinetics of the colour recovery processes in irradiated "Red Acrylic" dosimeters was studied. It was found that the decay is due to diffusion of oxygen into the matrix and a thermal decay takes place, too. The diffusion processes result in the appearance of a clear surface layer which becomes thicker and thicker. This layer is separated by a sharp boundary surface from the dark region. The activation energy of the oxygen diffusion was determined from the kinetics. In samples irradiated and heat-treated in noble gas this process does not take place but it was observed that in pure oxygen, chlorine and in air the colour recovery was similar.
