Researchers measured electromagnetic fields at two commercial solar farms in California, testing frequencies from 0 Hz to 3 GHz around solar panels, inverters, and transformers. All measured EMF levels fell well below established safety limits set by IEEE and ICNIRP. The highest magnetic fields occurred near transformers and inverters, with radiofrequency emissions between 5-100 kHz coming from the inverters.

Researchers measured extremely low-frequency magnetic fields around electric substations at a petrochemical plant in Iran to identify hazardous exposure zones for workers. They found magnetic field levels ranging from 0.02 to 49.90 microtesla (μT), with the highest exposures near transformers, incoming panels, and cables. The study created hazard maps to help protect workers from chronic EMF exposure in industrial settings.

Researchers discovered that extremely low frequency magnetic fields can alter how the body responds to pain and opioid medications, with effects documented across species from snails to humans over 30 years of study. The findings show these magnetic fields can both increase and decrease pain sensitivity depending on exposure conditions. This research opens new possibilities for treating chronic pain using electromagnetic therapy.

Researchers examined whether weak 50/60 Hz magnetic fields from power lines could disrupt our internal body clocks by affecting cryptochromes, special proteins that help regulate circadian rhythms. The study tested the basic scientific premise behind this 'cryptochrome hypothesis' by looking at how static magnetic fields might change these proteins' chemical balance. This research aims to understand if everyday electromagnetic exposure could be throwing off our natural sleep-wake cycles.

Austrian researchers measured electromagnetic field levels in 219 bedrooms over six years (2006-2012), tracking changes in both power line frequencies and wireless radiation. They found power line electric fields decreased by 40% while wireless radiation nearly doubled, with urban areas showing 3.4 times higher wireless exposure than rural locations. The study reveals how our bedroom EMF environment has shifted dramatically toward wireless sources.

Swedish researchers validated how accurately people remember when they first started using mobile phones by comparing self-reported dates with actual cellular network records from 207 participants. They found substantial errors in memory, with people typically misremembering their start date by several years, though both brain tumor patients and healthy controls showed similar recall problems.

This European study examined how people perceive risks from different radiofrequency EMF sources like cell towers and mobile phones, and whether better knowledge about EMF exposure affects their concerns. Researchers found that people worry most about cell towers compared to other RF sources, and surprisingly, those with better technical knowledge about EMF exposure actually had higher risk perception, especially for mobile phones.

This 2015 Indian public health review examined the documented health effects of mobile phone radiofrequency radiation, including short-term impacts on sleep, heart rate, and blood pressure, plus long-term cancer risks. The authors called for stronger government regulations, enforcement of phone-free zones, and public education campaigns to reduce exposure.

Researchers used computer modeling to test how the human body affects radiofrequency exposure measurements from personal monitoring devices worn at different body locations. They found that measurement errors ranged from -96% to +133% relative to the unperturbed field depending on where the device was worn, with a position on the waist toward the back or on the front of the chest reducing the range of uncertainty.

This 2015 review analyzed multiple studies on mobile phone radiation and brain tumors, focusing on the French CERENAT study which found increased glioma risk with long-term mobile phone use. The authors concluded that radiofrequency electromagnetic fields from mobile phones should be classified as a 'probable human carcinogen' by international health agencies.

Researchers measured radiofrequency radiation exposure at two television stations in Ghana to assess worker safety. They found RF levels ranging from 0.006 to 58.5 volts per meter, which stayed below occupational safety limits but exceeded public exposure guidelines by up to 4.3 times in some areas. This highlights how workplace RF exposure can be significantly higher than what's considered safe for the general public.

Researchers exposed Alzheimer's disease mice to 1950 MHz radiofrequency radiation (similar to cell phone frequencies) for 8 months and found it significantly reduced amyloid plaques in the brain and improved memory function. The study suggests RF exposure may have protective effects against Alzheimer's pathology, though only in mice already showing disease symptoms, not healthy brains.

Israeli researchers measured radiofrequency radiation exposure across 25 occupations using RF equipment, from medical devices to walkie-talkies. They found walkie-talkie users had the highest exposures at 94% of safety limits, while most other jobs stayed below 1% of recommended thresholds. The study reveals significant workplace RF exposure variations that workers and employers should understand.

This 2015 scientific review examined how radiofrequency electromagnetic fields from cell towers and wireless infrastructure may disrupt wildlife navigation systems. The research found that RF radiation at environmental levels commonly found in urban areas and near base stations can interfere with animals' ability to sense Earth's magnetic field for orientation. This poses particular risks for migratory birds and insects that rely on magnetic navigation.

This 2015 policy review examined how different countries and organizations advise on children's exposure to radiofrequency electromagnetic fields from wireless devices. The researcher found wildly inconsistent approaches, ranging from no special precautions to extensive warnings, product bans, and mandatory exposure labeling. The review calls for minimum RF-EMF exposure for children as a basic health precaution, given that long-term safety cannot be guaranteed.

Researchers measured radiofrequency radiation levels inside buildings across 343 locations in Hebron, Palestine, from sources like cell towers, FM radio, WiFi, and cordless phones. They found maximum exposure levels about 100 times below international safety guidelines, with FM radio contributing nearly half of total indoor RF exposure. The study reveals that most indoor RF exposure (73%) actually comes from outdoor sources like broadcasting stations and cell towers.

Chinese researchers surveyed over 32,000 pregnant women in Beijing from 2000 to 2013 to identify risk factors for early miscarriage. They found that living within 100 meters of a cell tower was an independent risk factor for spontaneous abortion, along with having a cold during pregnancy, home decoration, pet ownership, and high anxiety levels. The study suggests that proximity to wireless infrastructure may pose reproductive health risks.

Researchers exposed human sperm samples from 124 men to cell phone radiation for one hour in laboratory conditions. The radiation significantly reduced sperm movement and increased DNA damage, with the worst effects seen in men who already had fertility problems. This suggests that cell phone radiation may harm male fertility by damaging sperm quality and genetic material.

Researchers exposed rats to 2100 MHz radiofrequency radiation (simulating 3G cell phone signals) for 6 hours daily over 10 or 40 days to study effects on nasal tissue and mucus clearance. The exposed rats showed significant damage to nasal tissue, including cell death, loss of protective cilia (tiny hair-like structures), and impaired ability to clear mucus from nasal passages. This matters because our nasal passages are a primary defense against airborne pathogens, and cell phone radiation may be compromising this natural protective mechanism.

Dutch researchers followed over 120,000 people for 17 years to see if workplace exposures increased dementia death risk. They found that men exposed to metals, chlorinated solvents, and extremely low frequency magnetic fields (ELF-MF) at work had higher rates of non-vascular dementia mortality. The strongest link was with metals exposure, showing a 35% increased risk.

Dutch researchers followed over 120,000 people for 17 years to study whether workplace exposures increase Parkinson's disease deaths. They found that men with high occupational exposure to extremely low frequency magnetic fields (ELF-MF) had a 54% higher risk of dying from Parkinson's disease. This matters because ELF-MF exposure comes from power lines, electrical equipment, and many common workplace environments.

German researchers exposed mice to radiofrequency radiation at levels similar to cell phones and found significantly higher numbers of lung, liver, and lymph node tumors compared to unexposed animals. The tumor-promoting effects occurred at very low exposure levels - well below current safety limits for mobile phone users. This replication study confirms earlier findings that RF radiation may accelerate tumor growth even when it doesn't directly cause cancer.

Researchers exposed longhorn beetles to 50 Hz magnetic fields (the same frequency as power lines) and measured how their brain neurons responded. They found that square wave magnetic fields caused measurable changes in neural activity after 10-15 minutes of exposure, while sine wave fields did not. This demonstrates that even insects show biological responses to power-frequency magnetic fields, and that the waveform shape matters for biological effects.

Researchers exposed a mouse spermatocyte-derived GC-2 cell line intermittently to 50 Hz ELF-EMF at intensities of 1, 2, or 3 mT, or to 1800 MHz RF-EMF in GSM-Talk mode at SAR values of 1, 2, or 4 W/kg. After 24 hours of exposure, neither ELF-EMF nor RF-EMF affected cell viability. ELF-EMF exposure significantly increased DNA strand breaks at 3 mT, while RF-EMF exposure significantly induced oxidative DNA base damage at a SAR of 4 W/kg. The researchers suggest that both field types may produce genotoxicity at relatively high intensities but through different patterns of DNA damage.
