MICROWAVE ABSORPTION MEASUREMENTS
O. M. Salati · 1959
Early microwave absorption research from 1959 established fundamental tissue interaction principles still relevant to modern EMF safety.
Plain English Summary
This 1959 conference paper by Salati examined how human biological materials absorb microwave radiation, focusing on electromagnetic field interactions and radar cross-section measurements. The research investigated the fundamental properties of how microwave energy penetrates and is absorbed by human tissue. This early work helped establish scientific understanding of microwave-tissue interactions that remains relevant to modern EMF exposure assessment.
Why This Matters
This 1959 research represents pioneering work in understanding how human tissue absorbs microwave radiation. While conducted decades before cell phones and WiFi became ubiquitous, the fundamental physics Salati investigated remains unchanged. The science demonstrates that human tissue acts as a complex absorber of microwave energy, with different tissues showing varying absorption rates based on their water content and electrical properties.
What this means for you is that the microwave absorption characteristics documented in early research like this form the foundation for modern safety standards. However, the reality is that our daily exposure to microwave radiation has increased exponentially since 1959. Where Salati studied basic absorption properties under controlled conditions, we now live surrounded by microwave-emitting devices operating at similar frequencies. The evidence shows that understanding tissue absorption remains as relevant today as it was 65 years ago.

Study Details
The objective of this work is primarily concerned with the determination of the relative absorption cross-section of man.
The experimental program involves measuring the temperature rise of spheres or cylinders simulating ...
The power density achieved is expected to be at least 20 milliwatts per sq. cm. The scattering cross...
The phase of the overall program concerning absorption coefficients is considered concluded. No further work concerning absorption coefficients need be contemplated. The study emphasizes the importance of free field measurements for correlating biological experiments and the need for standardization of animal experiments to compare effects of microwave power at various frequencies.
