Abstract:
There is increasing evidence that extremely low frequency (ELF) electromagnetic fields (EMFs) interact with immune cells. Even
more evident is that immune cells are activated when exposed to these fields for a short period. Signal specificity and dosimetry
appear to play a role. In this study, four groups of laboratory mice received daily exposure to a specific electromagnetic field with
an intensity of 5μT for one hour, four hours and twenty-four hours (continuously) respectively for a period of seven days. The control
group received no exposure and was used as standard for comparison. Following exposure, whole blood was analysed for leukocyte
count, CD3, CD4, CD8 and CD19 analysis. The results for the twenty-four hour exposure group indicated increased total leukocyte,
lymphocyte, CD3 and CD4 values and a decreased neutrophil values. These findings provide evidence that the immune system is
indeed stimulated by exposure to EMFs.
