title: [The influence of geomagnetic field on blood leukocyte radiosensitivity and gender determination in humans].
abstract: The gender and age features of the geomagnetic field (GMF) influence (K-indexes) on the leukocyte radiosensitivity (S) in human blood in case of normal and enhanced levels of metal-ecotoxicants (Pb, Cd, Hg, Mn, Zn, Cu) in blood was studied, as well as the impact of the GMF intensity alterations on the child gender determination. In the whole studied population (n = 244) it was observed a negative relationship between S- and K-indexes. It was shown that the most changes of blood leukocyte radiosensitivity depended on the GMF oscillations in men older than 45 years. In case of metal-ecotoxicant concentrations in blood near normal level there were observed significant relationships between S- and K-indexes, which was infringed by more than 2-fold excess of these toxicant concentrations in blood. Retrospective analysis showed that in case of the GMF intensity enhancement in the conception moment the girls were born mostly, and in case of the lowering--the boys were.
