Scientists measured how much radiofrequency energy mice and rats absorb when exposed to three different frequencies: 2450 MHz (microwave oven frequency), 425 MHz, and 100 MHz. Using precise calorimetry techniques, they found that energy absorption rates varied significantly based on the animal's size, body orientation, and the specific frequency used. This foundational research helps establish how biological tissues absorb EMF energy at different frequencies.
