Microwave radiation at 10-200 mW/cm² disrupted blood chemistry and metabolism in rabbits, with effects occurring even at the lowest exposure level.

Plain English Summary

Summary written for general audiences

Researchers exposed white rabbits to different levels of microwave radiation and measured changes in their blood chemistry. They found that even at the lowest exposure level (10 mW/cm²), the microwaves disrupted protein metabolism, altered blood sugar levels, and changed the activity of important enzymes in the blood. These blood changes occurred in a dose-dependent manner, with higher microwave intensities causing more pronounced effects.

Why This Matters

This 1995 study provides early evidence that microwave radiation can disrupt fundamental metabolic processes at the cellular level. The exposure levels tested (10-200 mW/cm²) span a range that includes levels found near some industrial microwave equipment and high-powered radar systems, though they're generally higher than typical consumer device exposures. What's particularly significant is that biological effects were observed at the lowest tested level of 10 mW/cm², suggesting there may not be a clear threshold below which microwave exposure is completely safe. The fact that these researchers identified specific blood markers that change with microwave exposure also provides a potential framework for monitoring biological effects in humans, though much more research would be needed to establish clinical relevance.
