THE ABSORPTION OF ELECTROMAGNETIC ENERGY IN BODY TISSUES: A Review and Critical Analysis
Herman P. Schwan, Geo. Morris Piersol · 1954
This 1954 foundational study established key principles of EMF tissue absorption that remain relevant for modern wireless safety.
Plain English Summary
This 1954 review by Herman Schwan examined how radiofrequency electromagnetic waves are absorbed by human body tissues, focusing on therapeutic applications and worker safety concerns. The study analyzed the physical mechanisms of EMF absorption in different tissues and evaluated both medical benefits and potential hazards. This foundational research helped establish our early understanding of how electromagnetic energy interacts with biological systems.
Why This Matters
This landmark 1954 review represents one of the earliest comprehensive examinations of electromagnetic energy absorption in human tissues. What makes Schwan's work particularly significant is that it emerged during the dawn of the modern EMF era, when researchers were just beginning to understand how radiofrequency radiation interacts with biological systems. The science demonstrates that even seven decades ago, scientists recognized the dual nature of electromagnetic exposure - its therapeutic potential alongside legitimate safety concerns for workers and the public.
The reality is that many of the fundamental principles Schwan outlined about tissue absorption and electromagnetic propagation remain relevant today as we grapple with exponentially higher EMF exposures from wireless devices, 5G networks, and smart technologies. This early research laid the groundwork for our current understanding that different tissues absorb electromagnetic energy at different rates, a concept that directly applies to modern concerns about EMF exposure from cell phones, WiFi, and other wireless technologies.
