These authors have previously reported that exposure of rats to microwaves could cause an increase in DNA strand breaks in their brain cells. In their latest experiment they have repeated their earlier observations and have examined whether the effects are influenced by a temporally incoherent magnetic field.

Male Sprague-Dawley rats were used. They were exposed to 2450 MHz microwaves for 2 hours at a whole body average SAR of 0.6 W/kg. They were then sacrificed and preparations of brain cells prepared. A microgel electrophoresis assay for DNA strand breaks was carried out. The exposed rats were compared with sham-exposed animals, and with two other groups. One group was exposed to an incoherent magnetic field (noise) and the other was exposed to microwaves + noise.

The authors reported a statistically significant increase in single- and double-strand breaks in microwave -exposed rats. The other groups were not significantly different from the sham-exposed. They surmised that their results support a hypothesis that the incoherent magnetic field disturbed cellular sensing to an electromagnetic field.
