Smart meters have been widely deployed to measure electricity, gas, and water usage, transmitting data wirelessly to utility companies. This has raised concerns about RF-EMF exposure from these devices, which are often mounted on exterior walls of homes.
Smart meters typically transmit data in brief bursts rather than continuously, resulting in different exposure patterns than devices like WiFi routers or cell phones. However, cumulative exposure and proximity to living spaces remain concerns for some homeowners.
This page examines research relevant to understanding smart meter EMF exposure and potential health effects.

This was one of the first systematic investigations into microwave-induced eye damage in real-world occupational settings.
COL Budd Appleton, George C. McCrossan · 1972
Military researchers examined the eyes of personnel with the highest occupational microwave exposure levels alongside 135 unexposed controls, with examiners unaware of who had been exposed. They found no difference in lens abnormalities (cataracts, opacities, or other damage) between the two groups, concluding that chronic microwave exposure in military settings wasn't causing cataracts.
A. CHAMAY, J. RICHEZ, L. BIELER · 1972
This 1972 French research by Dr. Chamay investigated how micro-electric currents influence bone formation (osteogenesis), exploring the piezoelectric properties of bone tissue. The study examined how extremely low frequency electrical fields affect the natural bone-building process. This early work helped establish the scientific foundation for understanding how electrical fields interact with living bone tissue.
Eugene Edmonds, James Hartranft · 1971
In 1970, Orange County health officials tested 93 microwave ovens and found 7% of home units and 23% of commercial ovens leaked radiation above the industry safety standard. The study revealed commercial food service workers faced the greatest exposure risk due to longer operating times and poor maintenance.
Dronov, I. S., Kiritseva, A. D. · 1971
