Application of Luminescence Changes in Organic Solids to Dosimetry

Abstract
The degradation of photoluminescence in anthracene and in naphthalene has been studied under gamma-ray and electron irradiation over the range 3×105 to 2×108 rep. For both materials the variation of brightness with Co60 gamma-ray dose D, in rep, may be represented by (I/I0)=(1+AD)−1, where A=8.5×10−7 for anthracene and A=14×10−7 for naphthalene. Irradiation also produces a radiophotoluminescence in naphthalene, with emission in the visible spectral region. Both the degradation and radiophotoluminescence are stable with time at room temperature. The employment of these effects for dosimetry is discussed.
