Beschreibungen/Notizen

• The effect of gamma radiation from a 60 Co source on the intensity of re-emitted luminescence at the output of WLS fibers of the Y-11M and O-2M types and the subsequent restoration of the characteristics of the irradiated fibers after holding them at room temperature are investigated. Irradiation, starting from a low dose rate (0.048 MRad/h) to a dose of 1 MRad, leads to an insignificant decrease in the intensity of re-emitted luminescence at the output of both types of fibers, and with a further increase in the dose, the course of the curve practically does not change. When irradiated with a dose rate of 0.158 MRad/h, the characteristics of both types of fibers deteriorate significantly. When the irradiated samples are kept at room temperature, the fiber characteristics are restored.
