Modulated microwave signals altered mouse immune responses at power levels 1,000 times lower than cell phones, while unmodulated signals showed no effect.

Plain English Summary

Summary written for general audiences

French researchers exposed mice to low-power pulsed microwaves (similar to radar frequencies) for 10 hours daily over five days to test effects on immune system function. They found that simple pulsed signals had little effect, but when the signals included additional amplitude modulation, the mice showed significant changes in antibody production - some frequencies strengthened immune responses while others weakened them.

Study Details

Irradiation by pulsed microwaves (9.4 GHz, 1 microsecond pulses at 1,000/s), both with and without concurrent amplitude modulation (AM) by a sinusoid at discrete frequencies between 14 and 41 MHz, was assessed for effects on the immune system of Balb/C mice.

The mice were immunized either by sheep red blood cells (SRBC) or by glutaric-anhydride conjugated b...

In the absence of AM, the pulsed field did not greatly alter immune responsiveness. In contrast, exp...
