The effect of two types of ionizing radiation was examined on active avoidance behaviour. Male Sprague-Dawley rats were trained to avoid footshock by jumping onto a retractable ledge. When irradiated with high-energy electrons or gamma photons, their performance was degraded in a dose-dependent manner. However, electrons were 1.6 times as effective as gamma photons with ED50s of 62 and 102 Gy, respectively. All animals recovered within 24 min for all doses used. The data suggest that different types of ionizing radiation may not be equivalent when assessing their effect on behaviour.
研究了两种类型的电离辐射对主动回避行为的影响。雄性斯普拉格-道利大鼠经过训练，通过跳到可缩回的壁架上来避免足部电击。当用高能电子或γ光子照射时，它们的表现以剂量依赖的方式下降。然而，电子的效果是γ光子的1.6倍，其半数有效剂量（ED50）分别为62和102 Gy。对于所有使用的剂量，所有动物在24分钟内都恢复了。数据表明，在评估不同类型的电离辐射对行为的影响时，它们可能并不等效。
