摘要

在60Co γ射线源下，以1.838 × 10−2 Gy/s的剂量率照射几种类型的有机闪烁体，研究其在空气和氮气环境中吸收剂量范围为103 ~ 4 × 104 Gy的辐射损伤。通过对每个样品辐照前后的光透射和光输出的变化来测量辐射损伤的影响。观察到不同程度的损害，与闪烁体的类型和辐射环境有关。

Measurement of radiation damage on organic scintillators caused by gamma-rays and its recovery time

Several types of organic scintillator were exposed to a ⁶⁰Co γ-ray source at a dose rate of 1.838 x 10⁻² Gy/s in order to study the radiation damage in the range 10³-4 x 10⁴ Gy of absorbed dose, both in air and in nitrogen environment. The effect of radiation damage was measured by the change in optical transmission and light output before and after the irradiation of each sample. A different degree of damage, related to the type of scintillator and to the radiation environment, was observed.
