[Effect of electromagnetic radiation on T-lymphocyte subpopulations and immunoglobulin level in human blood serum after occupational exposure].

: The study was aimed at evaluation of the total lymphocyte, the T lymphocyte (T3), the T helper (T4) and the T suppressor (T8) count in the peripheral blood as well as of the IgG, IgA and IgM level in sera of 39 radar operators aged from 20 to 22 years. The operators were exposed to electromagnetic radiation at frequencies ranging from 390 MHz to 10.96 GHz and power from 500 kW to 1.5 MW for a period from 720 to 7560 hours. As compared to the control group in the radar operators a statistically significant decrease in the total T8 cell count and a significant increase in the IgM level was found pointing to the radiation induced disorders in lymphocyte system.
