MICROWAVE RADIATION EFFECTS PROGRAM
Wilbur P. Dayton · 1961
Scientists were studying microwave radiation health effects in 1961, yet today's wireless devices use the same frequencies with minimal safety oversight.
Plain English Summary
This 1961 technical report by Wilbur P. Dayton established one of the early formal research programs investigating the biological effects of microwave radiation. The document represents pioneering work in understanding how microwave frequencies might affect living systems, conducted during the Cold War era when microwave technology was rapidly expanding. This research laid important groundwork for decades of EMF health studies that followed.
Why This Matters
The significance of this 1961 microwave effects program cannot be overstated in the history of EMF research. This represents some of the earliest systematic investigation into microwave radiation's biological impacts, conducted at a time when radar systems and microwave communications were proliferating rapidly. What makes this particularly relevant today is that the microwave frequencies studied in early programs like this are essentially the same frequencies now used in WiFi routers, cell phones, and wireless devices throughout our homes and workplaces.
The reality is that while we had researchers investigating potential microwave health effects over 60 years ago, regulatory agencies today still largely ignore this accumulated body of research. The science demonstrates that concerns about microwave radiation aren't new or fringe - they've been part of legitimate scientific inquiry since the technology's early development. You don't have to accept that decades of research can be dismissed simply because it's inconvenient for wireless industry profits.
Finding
Animal experiments have demonstrated that continuous exposure for an hour or more at power levels in excess of 80 milliwatts per square centimeter are required to induce detrimental effects in the form of heat exhaustion and burn.

There have been no serious injuries and certainly no deaths which could be properly attributed to exposure to the beam of a radar set. Radar beams from rotating antennas appear to be less dangerous than those from stationary antennas. Moving air appears to markedly decrease the detrimental effects of microwave radiation. The current Air Force exposure criteria of 0.01 watt per square centimeter does not consider time of exposure. Exposure from a revolving source, since it is intermittent, is less hazardous. Environmental temperature and forced air currents have a marked effect on heating and must be considered when evaluating hazardous conditions.
