Abstract: Abstract: Several pieces of the plastic scintillator SCSN-38 were exposed to -rays in air and were simultaneously illuminated with visible light. A comparison of illuminated and unilluminated samples showed that the permanent radiation induced absorption was smaller by a factor four when the samples were illuminated with blue light. A similar effect has been observed in clear polystyrene. [Copyright &y& Elsevier]
