As part of the wider interest in the effects of ionizing radiation on non-human biota, this investigation was carried out to study early radiation damage to the eye-lenses of rainbow trout. Lenses were cultured and irradiated to doses of 1.1 Gy and 2.2 Gy with low-energy X-rays of 40 kV. Laser focal analysis was used to track changes in focal lengths across the lenses post-irradiation. Changes in focal length variability (FLV) were measured to determine whether this could give an indication of the early effects of radiation on lens health. No statistically significant differences in FLV between the control and irradiated lenses within 10 days post-irradiation were observed. FLV was found to be 0.09 ± 0.02 mm for 2.2 Gy lenses, 0.06 ± 0.01 mm for 1.1 Gy lenses, and 0.11 ± 0.02 mm for control lenses at the end of the observation period.

作为对电离辐射对非人类生物群影响的更广泛兴趣的一部分，进行这项调查是为了研究虹鳟鱼眼晶状体的早期辐射损伤。培养镜片并用 40 kV 的低能 X 射线照射剂量为 1.1 Gy 和 2.2 Gy。激光焦距分析用于跟踪照射后透镜焦距的变化。测量焦距可变性 (FLV) 的变化以确定这是否可以指示辐射对晶状体健康的早期影响。在照射后 10 天内观察到对照镜片和照射镜片之间的 FLV 没有统计学上的显着差异。在观察期结束时，2.2 Gy 镜片的 FLV 为 0.09 ± 0.02 mm，1.1 Gy 镜片的 FLV 为 0.06 ± 0.01 mm，对照镜片的 FLV 为 0.11 ± 0.02 mm。
