NEUROENDOCRINE EFFECTS OF MICROWAVE RADIATION
William C. Milroy · 1972
Early 1972 research investigated microwave radiation's effects on hormone systems, laying groundwork for understanding EMF's impact on thyroid function.
Plain English Summary
This 1972 conference paper examined how microwave radiation affects the neuroendocrine system in rats, specifically looking at thyroid function. The research was part of early investigations into biological effects of microwave exposure on hormone-producing glands. While specific findings aren't available, this represents foundational work studying EMF effects on critical body systems.
Why This Matters
This early research from 1972 represents crucial foundational work examining how microwave radiation affects our hormone systems. The focus on neuroendocrine effects, particularly thyroid function, was prescient given what we now understand about EMF's ability to disrupt cellular signaling pathways that control hormone production and regulation. The thyroid gland is particularly vulnerable to electromagnetic interference because it relies on precise cellular communication to regulate metabolism, growth, and development.
What makes this research significant is its timing. In 1972, microwave technology was just beginning its march into everyday life, yet scientists were already investigating biological effects beyond simple heating. Today's microwave exposures from WiFi routers, cell phones, and smart devices operate at similar frequencies to those studied in early research like this, making these foundational studies more relevant than ever for understanding our current exposure landscape.

- Power Density
- 100 mW/cm²
Exposure Context
This study used 100 mW/cm² for radio frequency:
- 10,000Mx above the Building Biology guideline of 0.1 μW/m²
- 166.7Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
To evaluate and correlate thyroid and thyrotropic activity in microwave exposed rats in an attempt to determine the mechanism by which thyroid function is altered.
Mature male rats were exposed to microwave radiation at 2450 MHz from a Raytheon Microtherm generato...
Behavioral changes were as would be expected for equivalent body heating of any type. At 100 mW/cm² ...
Based on the preliminary data, it would appear that no specific effect of microwave radiation on the hypophysio-thyroid axis can be demonstrated. Those effects which have been demonstrated can be adequately explained on the basis of heating. This is consistent with the thermal theory of microwave bioeffects rather than the direct neuroendocrine stimulation theory. Thorough analysis of the data is presently underway to determine the presence of any possible trends which may contradict this conclusion.
