The effect of gamma radiation from a ⁶⁰Co 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.

来自⁶⁰ Co的伽马辐射对Y-11M和O-2M类型的WLS光纤输出处重新发射的发光强度的影响以及将辐照光纤保持在室温后其特性的恢复研究温度。从低剂量率（0.048 MRad / h）到1 MRad的剂量进行辐照，会导致两种类型的光纤输出处的重新发光强度显着降低，并且辐射强度会进一步增加。剂量，曲线的过程实际上不改变。当以0.158 MRad / h的剂量率进行辐照时，两种类型的纤维的特性都会大大降低。当被辐照的样品保持在室温下时，纤维特性得以恢复。
