This analysis examined how radiofrequency and microwave radiation heats human tissue across different frequencies, focusing on thermal safety standards.

Researchers exposed rhesus monkeys to 1.29 GHz pulsed microwave radiation for 8 hours at power densities of 28 and 38 mW/cm², measuring body temperature and hormone levels. The monkeys experienced significant temperature increases (0.6°C to 1.5°C) during exposure, but showed no changes in growth hormone, cortisol, or thyroxine levels. This suggests that while microwave radiation can heat the body, it may not immediately disrupt key hormonal systems.

Researchers trained rats to perform precise timing tasks, then exposed them to 2.8 GHz pulsed microwaves at power levels similar to early cell phones.

Importantly, the same radiation had no effect when the timing task was made easier, suggesting the microwaves specifically interfere with complex behavioral control.
