人们已经知道存在着这样一种可能性已有多年,即低剂量辐射会在细胞和机体内引起一些表明它有补偿辐射效应能力的变化。有人指出,对低水平辐射随机效应风险的估计也许一直过高,因为一直没有把被称为适应或适应性反应的过程考虑进去。适应性反应这一术语用于表示这洋一种可能性.即小的辐射剂量(有人称它为适应剂量,有人称它为诱发荆量、先导剂量或调节剂量)可通过引发一些过程来调节细胞。这些过程或者减少恶性自然发生率,或者减少由更大的 It has been known for many years that there is a possibility that low-dose radiation causes some changes in cells and in the body indicating its ability to compensate for radiation effects. It was pointed out that the estimate of the risk of random effects of low-level radiation might have been consistently too high, as no process known as adaptive or adaptive response has been taken into account. The term adaptive response is used to indicate that it is a possibility that a small radiation dose (some call it an adapted dose, some call it an inducing dose, a leading dose, or a regimen of a dose) that regulates the cell by triggering some process . These processes either reduce the incidence of malignant or reduce by greater
