This 1978 thesis developed mathematical methods still used today to calculate electromagnetic energy absorption in human bodies.

Plain English Summary

Summary written for general audiences

This 1978 doctoral thesis developed numerical methods to calculate how electromagnetic energy is absorbed by the human body. The research created mathematical models to predict energy absorption patterns in human tissue when exposed to electromagnetic fields. This foundational work helped establish the scientific basis for understanding EMF exposure levels in humans.

Why This Matters

This thesis represents pioneering work in EMF dosimetry - the science of measuring electromagnetic energy absorption in biological tissue. In 1978, Hagmann was developing the mathematical foundations that would later become essential for setting safety standards and designing safer technology. The numerical methods explored in this research likely contributed to our modern understanding of Specific Absorption Rate (SAR) calculations, which determine how much electromagnetic energy your body absorbs from devices like cell phones and WiFi routers. What makes this work particularly significant is its timing - this was early foundational research that helped establish the scientific framework we still use today to assess EMF exposure risks. The mathematical models developed here continue to inform how we evaluate whether our daily technology use stays within recommended safety limits.
