Experimentation indicates: under the same radiation dose, ionizing radiation damage at low dose rate is more than that at high dose rate.

试验表明：在相同辐射剂量下，低剂量率辐照损伤比高剂量率大。

The heart rate of the dogs did not undergo obvious changes in response to the injection at a low dose, but median and high doses of the injection produced obvious effects.

钩吻素子注射液低剂量对犬的心率无影响，但中、高剂量给药前后犬的心率有显著性差异。
