摘要

本文提出了由于电离辐射对人类的影响而产生的有害因素和有益因素之间相互竞争过程的平衡方程的概念。采用Lotka-Volterra方程描述了低剂量辐射环境下种群的演化过程。平衡方程是Lotka-Volterra方程随时间稳定的结果,它正确地描述了大多数人口,其中有害(癌症)过程的概率等于有益(刺激)过程的概率。结果表明,大多数人的反应是阈值剂量-反应曲线,辐射敏感者的反应是线性模型,辐射抵抗者的反应是辐照模型。

Radiation and evolution: from Lotka-Volterra equation to balance equation
The paper presents the concept of balance equation as a result of jostling process between detrimental and beneficial factors due to ionising radiation impact on the human population. The Lotka-Volterra equation was used to describe the evolution process of the population in low-dose radiation environment. The balance equation, which is a result of Lotka-Volterra's equation stabilisation over time, describes correctly most of the human population, wherein the probability of detrimental (cancerous) processes equals the probability of beneficial (hormetic) processes. It concludes that most of people respond via threshold dose-response curve, while radiosensitive people respond using linear model and radioresistant people respond using hormetic one.
