Changes in fluorescence spectral characteristics of blood nuclear cells by the action of physical factors associated with 11- and 22-year cyclic variations in solar activity

A correlation between the functional (synthetic) activity of animal blood lymphocytes and the intensity of radiation of the Sun at a frequency of 2800 MHz in 2000 and 2002 was studied. The results were compared with the data obtained in 1993 and 1994. These data suggest that there are seasonal regularities in the interrelationship of the processes studied. A change in the sign of the correlation coefficients at the maximum of the 23rd solar cycle was shown. Possible mechanisms of the phenomena are discussed.
