The effect of the dose rate from 0.00022 to 0.0032 MGy/h and the radiation dose of 0.043 and 0.2 MGy of the ⁶⁰Co gamma source, as well as of oxidative conditions on the optical transmission and absorption spectra of plastic scintillators of the BC-408 (Bicron, USA), UPS-923A (Amcrys-H, Ukraine), and LHE (JINR, Russia) brands has been investigated at 300 K. It has been shown that the optical transmission of scintillators in the range of 400–850 nm decreases when increasing radiation dose. There was no noticeable effect of adsorbed oxygen on the induced optical losses under these conditions.

伽马辐射聚合物闪烁体的光学特性

⁶⁰ Coγ源的剂量率从0.00022到0.0032 MGy / h以及0.043和0.2 MGy的辐射剂量以及氧化条件对BC-408塑料闪烁体的光学透射和吸收光谱的影响（美国Bicron），UPS-923A（乌克兰Amcrys-H）和LHE（俄罗斯JINR）品牌已在300 K下进行了研究。结果表明，闪烁体的光学透射范围为400–850 nm当增加辐射剂量时减少。在这些条件下，吸附的氧对引起的光学损失没有明显影响。
