Damage to plastic scintillators by ionizing radiation

The Soviet Journal of Atomic Energy Aims and scope

Abstract

The intensity of the luminescence emission from plastic scintillators in which polystyrene is used as a base material is reduced as the doses of the α- and β-radiation absorbed by the scintillator are increased. Furthermore, irradiation is characterized by a reduced transmission of the luminescent light of the plastic scintillators which, however, is not sufficient to explain quantitatively the reduction in the intensity of emission which is observed. The reduction of luminescent yield is associated with radiation damage of the plastic scintillators. For 50% damage in plastic scintillators a dose of α-radiation of approximately 6·109 erg/g is required, that is, a factor of 50 greater than that required to produce the same damage in an anthracene single-crystal.
