Abstract: The effects of dose rate and dose of $^{60}$Co gamma-irradiation and oxidation on optical transmission and absorption spectra of plastic scintillators of BC-408 (USA), UPS-923A (Ukraine) and LHE (JINR) were studied at 300 K in air and hermetic pack at dose rates within 0.00022 до 0.0032 МGy/h and to doses 0.043 и 0.2 МGy. The irradiation increases the transmission losses in the range of 400–850 nm as the dose grows. It was not found a noticeable influence of adsorbed oxygen on the induced optical losses at the mentioned conditions.

Keywords: plastic scintillators, gamma-irradiation, optical transmission, optical absorption, adsorbed oxygen.
