[The effect of various occupational exposures to microwave radiation on the concentrations of immunoglobulins and T lymphocyte subsets].

Abstract

The immunoglobulins' concentrations and T lymphocyte subsets during occupational exposures to microwave radiation were assessed. In the workers of retransmission TV center and center of satellite communications on increased IgG and IgA concentration and decreased count of lymphocytes and T8 cells was found. However, in the radar operators IgM concentration was elevated and a decrease in the total T8 cell count was observed. The different behaviour of examined immunological parameters indicate that the effect of microwave radiation on immune system depends on character of an exposure. Disorders in the immunoglobulins' concentrations and in the T8 cell count did not cause any clinical consequences.

Main findings

Among workers at a retransmission TV center and a satellite communications center, increased IgG and IgA concentrations and decreased lymphocyte and T8 cell counts were reported. Among radar operators, IgM concentration was elevated and total T8 cell count decreased. The abstract states these immunological changes did not cause clinical consequences.

Outcomes measured

• Immunoglobulin concentrations (IgG, IgA, IgM)
• Lymphocyte count
• T lymphocyte subsets (T8 cells)
• Clinical consequences (not specified)

Limitations

• Sample size not reported in abstract
• Exposure metrics (frequency, intensity/SAR, duration) not reported
• Study design details and comparison group not described in abstract
• Clinical outcomes not specified beyond statement of no clinical consequences

Suggested hubs

• occupational-exposure (0.9)
  Assesses immune parameters in workers occupationally exposed to microwave radiation (TV retransmission, satellite communications, radar).
