Abstract

Immunoglobulin concentrations and T-lymphocyte subsets in workers of TV re-transmission and satellite communication centres were assessed. An increase in IgG and IgA concentrations, an increased count of lymphocytes and T8 lymphocytes, an decreased count of NK cells and a lower value of T-helper/T-suppressor ratio were found. Neither disorders in immunoglobulin concentrations nor in the count of T8 and NK cells had any clinical implications.

Main findings

Workers occupationally exposed to microwave radiation showed increased IgG and IgA concentrations, increased lymphocyte and T8 lymphocyte counts, decreased NK cell counts, and a lower T-helper/T-suppressor ratio. The abstract states these immune changes had no clinical implications.
