Researchers exposed human blood to 2.8 GHz microwave radiation at high power levels (500-1000 mW/cm²) to test effects on glucose-6-phosphate dehydrogenase. While heat from the microwaves reduced enzyme activity by up to 80%, the study found no non-thermal effects from the microwave radiation itself. This suggests microwave effects on this enzyme are purely due to heating, not electromagnetic fields.
