人们假定,辐射是在均匀的细胞群体中通过按泊松分布规律随机发生的单径迹相互作用产生影响的。在数学上,可用一线性一二次式表述这种理论上的剂量-响应关系——即一种可归因于辐射效应的表现概率与所受剂量之间的数学关系。这种关系与大多数现有的流行病学数据相符。对于低辐射剂量,存在的辐射径迹非常之少,以致一个细胞(或细胞核)极不可能被一个以上的径迹穿过。因此,按照这些假定,剂量—响应关系几乎必定是线性的,与剂量率无关且没
It is hypothesized that radiation affects single-track interactions that occur randomly in a homogeneous cell population via Poisson distribution. In mathematics, a linear first-order or second-order formulation of this theoretical dose-response relationship can be used - that is, a mathematical relationship between the probability of performance attributable to the effects of radiation and the dose being received. This relationship is consistent with most of the available epidemiological data. For low radiation doses, there are very few radiation trails so that a cell (or cell nucleus) is extremely unlikely to be crossed by more than one track. Therefore, following these assumptions, the dose-response relationship is almost certainly linear, independent of the dose rate and not
