Effects of solar proton events in prevalence of congenital defects of development at children

In work results of statistical analysis of congenital developmental anomalies (CDA)cases at children in two cities of Murmansk oblast are presented. Comparison of CDA frequency to land increases of nucleon components of solar space beams – Ground Level Enhancement (GLE) associated with solar proton events, revealed significant correlations between the CDA of various classes and GLE cases. It is shown that CDA frequency with chromosomal anomalies (Q90-Q99) significantly correlates with the events of GLE which have happened one year prior to the birth of the child.
