Effect of the state of the geomagnetic field and solar activity on chromosome aberrations frequencies dynamics

Abstract

We establish the stochastic dependence of the frequency variation process of spontaneous chromosome aberrations in human blood lymphocytes on the deterministic periodic components of the state of the geomagnetic eld and solar activity by methods of mathematical modelling using experimental data. We prove that the random process of the frequency variation of spontaneous chromosome aberrations has a deterministic periodic component with two 4.8-and 67.5-year periods. Each of them is speci ed by the corresponding dominating time variation periods of the geomagnetic eld induction and the Wolf numbers.
