Lysina, G. G. · 1965
Soviet researchers in 1965 studied 100 workers chronically exposed to UHF radiation and found significant health effects including weakness, headaches, heart problems, and blood abnormalities. Workers exposed for over 3 years showed increased reticulocytes (immature red blood cells) and basophile granules - changes typically seen in radiation poisoning and anemia. The study documented clear biological effects even at exposures near or below the permitted threshold levels of that era.

This 1965 study examined military service records to determine if radar workers had higher rates of cataract formation compared to non-exposed personnel. The research investigated whether chronic, low-level microwave exposure from occupational radar use could increase cataract risk, building on previous animal studies that showed cataracts from repeated microwave exposure.

This 1965 Soviet research examined how environmental conditions affect the body's response to chronic ultra-high frequency (UHF) radiation exposure. The study investigated whether factors like temperature, humidity, and atmospheric pressure influence how humans and animals react to prolonged radiofrequency energy. This represents early recognition that EMF health effects may vary based on environmental context.

Soviet researchers in 1965 studied 402 radar operators working in different climates and found that hot weather increased the biological effects of microwave radiation exposure. Workers in Central Asia and the Caucasus showed more health changes than those in temperate European regions, despite similar radiation levels.
S. F. CLEARY, B. S. PASTERNACK, G. W. BEEBE · 1965
This 1965 military study examined cataract rates among radar workers exposed to microwave radiation during their service. Using military service records, researchers investigated whether chronic low-level microwave exposure increased cataract risk, following earlier reports of cataracts from acute radar overexposures. The study aimed to determine if occupational microwave workers faced elevated eye injury risks.

This 1964 Soviet study explored using enzymes as biological indicators to detect harmful environmental agents, including potential electromagnetic factors. The researchers proposed that enzyme systems could serve as highly sensitive and specific detectors for toxins that disrupt normal biological processes. This early work laid groundwork for understanding how biological systems respond to environmental stressors.
William R. Deichmann et al. · 1963
This 1963 study examined the health effects of chronic microwave radiation exposure on dogs using 24,000 MHz frequency at 20 milliwatts per square centimeter power density. The research represents early scientific investigation into biological effects of high-frequency electromagnetic fields. This work laid important groundwork for understanding how prolonged microwave exposure might affect living organisms.
William B. Deichmann · 1960
This 1960 University of Miami research report documented early studies on microwave radiation effects in experimental animals, including beagle dogs exposed to chronic microwave radiation with particular attention to leukemia development. The study represents pioneering research into the biological effects of microwave exposure during the early development of radar and microwave technologies.

This 1941 engineering study examined lightning strikes and electrical currents, measuring how lightning creates multiple electrical discharges and the wave patterns of these currents. Researchers found clear differences between direct lightning strikes and the electrical currents they produce in lightning arresters (protective devices).

This technical report presents measurement results for electric and magnetic field strengths in industrial settings. The study documented RF exposure levels across various workplace environments. Such measurements are crucial for establishing baseline exposure data and evaluating potential health risks from electromagnetic fields in occupational settings.

This Polish research examined health surveillance protocols for workers professionally exposed to microwave radiation in occupational settings. The study focused on monitoring health effects in personnel who work with microwave-emitting equipment as part of their job duties. This type of occupational health surveillance helps identify potential risks from chronic workplace microwave exposure.
Utility Tower Company
This technical report by Utility Tower Company examines broadcast tower infrastructure, focusing on installation specifications, climbing safety features, and structural engineering requirements including wind load calculations. While specific EMF measurements aren't detailed, broadcast towers are significant sources of radiofrequency radiation in communities. The report addresses the technical aspects of tower construction that affect both worker safety and public RF exposure levels.

Researchers exposed pregnant rats and their offspring to 100-MHz radiofrequency radiation for months, finding no effects on growth, immune function, or blood counts. However, the study revealed significant changes in brain acetylcholinesterase activity, an enzyme critical for nerve signal transmission.

This technical report examined the physiological effects of electric currents on the human body, with particular focus on dangerous outcomes like ventricular fibrillation (irregular heartbeat that can be fatal). The research documented how different levels of electrical current affect human physiology and established safety thresholds for electrical exposure.

This technical report examined occupational exposure to electromagnetic fields among workers near power lines and those using video display terminals (VDTs), focusing on potential links to leukemia and reproductive health effects. The research addressed workplace EMF exposure levels and associated health risks in occupational settings. This type of occupational health research helps establish safety guidelines for workers routinely exposed to EMF sources.

Researchers exposed four generations of rats to high-intensity 60 Hz electric fields (20 kV/m) for a full year, tracking body weight, water consumption, and organ changes. The study examined whether chronic exposure to power line frequency fields affects development and health across multiple generations. This research addresses concerns about long-term effects from electrical infrastructure.
Unknown authors
Researchers exposed rats to powerful 60-Hz electric fields (100 kV/m) for 30 days, then tested whether this changed their behavior around electric fields. Pre-exposed rats actually preferred staying in areas with electric fields, while unexposed rats avoided them, suggesting chronic exposure creates adaptation or tolerance.
