描述发生辐射致癌的非线性有效阈值 ( NET)关系 ,是对细胞 DNA改变的补偿生物反应的自然结果。加之 ,在流行病学资料分析中非线性数学关系的应用 ,也表现出非线性有效阈值。有效阈值是指低于该剂量时 ,发生癌的危险将减少到可忽视的或发现不到的水平。当考虑了细胞 DNA改变的正
Describing the Nonlinear Effective Threshold (NET) relationship in which radiation-induced oncogenesis occurs is a natural consequence of the compensatory biological response to changes in cellular DNA. In addition, the application of nonlinear mathematical relationships in epidemiological analysis also shows nonlinear effective thresholds. A valid threshold means below which the risk of cancer will be reduced to negligible or undetectable levels. When considering the positive changes of cellular DNA
