Researchers placed active mobile phones near honeybees and recorded their sounds to see if electromagnetic radiation affected bee behavior. The phones triggered 'worker piping,' a distress signal that bees normally make when their colony is threatened or preparing to swarm. This suggests that cell phone radiation disrupts normal bee communication and behavior patterns.

Brazilian researchers analyzed cancer deaths in Belo Horizonte from 1996-2006 and found that people living within 500 meters of cell phone base stations had significantly higher cancer mortality rates (34.76 per 10,000 residents) compared to those living farther away. The study used official death records and mapped the locations of 856 cell towers, measuring radiofrequency radiation levels up to 12.4 V/m in areas with the highest cancer rates.

Chinese researchers found that mice exposed to cell phone radiation (900 MHz) for two weeks before receiving potentially lethal gamma radiation survived longer and showed less blood tissue damage. This suggests low-level radiofrequency exposure may activate protective cellular responses against subsequent radiation harm.

Researchers exposed fruit fly embryos to a 60 millitesla static magnetic field (about 1,200 times stronger than Earth's magnetic field) throughout their development from egg to adult. The magnetic field exposure reduced survival rates in both species tested and altered their development timing. This suggests that strong magnetic fields can act as biological stressors that interfere with normal growth and development processes.

Researchers exposed rats to magnetic fields daily for five days. While motor skills remained normal, blood iron processing changed significantly - the iron-carrying protein increased 25% while actual iron levels dropped 16%. This shows magnetic fields can disrupt how bodies handle essential minerals.

Researchers placed active mobile phones near honeybee colonies and recorded the bees' sounds to see if cell phone radiation affected their behavior. They found that phones operating at 900 MHz caused bees to produce 'worker piping' signals, which normally indicate either preparation for swarming or that the colony is under stress. This suggests that cell phone radiation can disrupt normal bee communication and behavior patterns.

Researchers examined blood samples from people living near cell phone towers to look for genetic damage markers (micronucleus frequency and chromosomal aberrations) that could indicate cancer risk. They found no statistically significant differences between people living near towers and control groups. The study concluded that cell phone base stations do not produce important cancer-causing genetic changes.
Takahashi S et al. · 2010
Researchers exposed pregnant rats to 2.14 GHz radiofrequency radiation (similar to cell tower signals) for 20 hours daily throughout pregnancy and nursing. They found no harmful effects on the mothers, their offspring, or the next generation, examining everything from growth and development to memory and reproductive function. This suggests that exposure levels similar to those from cell towers may not cause developmental problems in mammals.

Researchers reviewed 17 studies examining whether cell phone towers cause health symptoms in people living nearby. They found that well-designed laboratory studies showed no connection between tower radiation and acute symptoms, while studies with less precise measurement methods were more likely to report effects. The review concluded there's strong evidence that cell tower radiation up to 10 volts per meter doesn't cause immediate symptoms, but insufficient data exists on long-term health effects.

Researchers exposed four rhesus monkeys to intense 2.8 GHz microwave radiation for 36 hours total over three weeks and measured any damage to the corneal endothelium (the inner layer of cells in the eye's cornea). The study found no changes in corneal cell density or thickness, even at power levels more than ten times higher than previous studies that reported eye damage. This suggests that microwave exposure at these levels may not harm this specific part of the eye.

Australian researchers developed detailed computer models to study how 900 MHz radiofrequency radiation (used in older cell phones) affects pregnant mice and their developing fetuses. They found that while both mother and fetuses absorbed the radiation, the fetuses experienced 14% lower energy absorption and 45% less temperature increase than their mothers. This research provides crucial data for understanding how RF exposure during pregnancy might affect developing offspring differently than adults.
Vermeeren G et al. · 2010
Researchers used computer modeling to study how reflective surfaces like walls and ground affect radiation absorption in the human body when exposed to cell tower antennas at various frequencies. They found that reflective environments can dramatically change radiation absorption levels - sometimes reducing it by 87% and other times increasing it by 630% compared to open space exposure. This reveals that current safety guidelines, which don't account for reflective environments, may not adequately protect people in real-world settings with buildings and metal surfaces.

Researchers surveyed 500 citizens in Bangladesh about their perceptions of health risks from mobile phones and cell towers. They found that people generally viewed the benefits of mobile technology as outweighing potential health risks, with emergency communication during natural disasters being a key benefit. Health concerns ranked relatively low compared to worries about crime and social disruption.

German researchers surveyed nearly 3,000 general practitioners to understand how many doctors believe electromagnetic fields cause health problems in their patients. They found that about one-third of German doctors (29-37%) think EMF exposure can cause health complaints even when radiation levels meet current safety standards. This suggests a significant portion of frontline healthcare providers see EMF-related health effects in their practice, despite official guidelines suggesting otherwise.

Researchers tracked radiofrequency radiation exposure from cell phone towers at five different locations over one week, comparing exposure levels to mobile phone traffic patterns throughout each day. They found that radiation exposure from cell towers directly correlates with phone usage patterns, with higher exposure occurring during peak calling times. This research provides a method for predicting radiation exposure levels based on mobile traffic data, which could help assess public exposure more accurately.

Researchers measured radiofrequency electromagnetic field (RF-EMF) exposure from wireless devices in five European countries using personal monitoring devices. They found that people receive the highest RF-EMF exposure while traveling in cars, trains, and buses-primarily from mobile phone use-with exposure levels up to 97% higher than in homes or offices. The study confirms that mobile phones are the dominant source of RF-EMF exposure in people's daily lives across different European urban environments.

Israeli researchers studied 50 healthy volunteers who regularly used mobile phones on one side of their head, measuring saliva production from their parotid glands (the large salivary glands near your ears). They found that the parotid gland on the phone-using side produced significantly more saliva but with lower protein content compared to the non-phone side. The authors concluded this indicates the glands are responding to continuous stress from radiofrequency radiation exposure.

Researchers exposed mice to 900-MHz microwave radiation (the same frequency used by many cell phones) before exposing them to gamma radiation to see how it affected their blood-forming system. They found that the microwave exposure actually protected the mice from radiation damage, with less severe harm to bone marrow and spleen tissues. The protective effect appeared to work by boosting growth factors and helping blood-forming cells survive the gamma radiation.

Korean researchers measured radiofrequency radiation levels from cell phone towers at 50 locations where the public had expressed health concerns. They found the highest exposure level was 1.5 volts per meter, which represents just 0.15% of international safety guidelines. The study suggests that actual exposure levels from cell towers are far below regulatory limits, even at locations where people were worried about potential health effects.

Researchers measured how much wireless radiation the body absorbs from cell phones and WiFi. They found that 1-year-old children absorb nearly three times more energy than adults from the same signal strength, revealing children face disproportionately higher exposure from everyday wireless devices.

Researchers measured radiofrequency (RF) electromagnetic field exposure from LTE cellular towers and other wireless sources at 30 locations in Stockholm, Sweden. They found that LTE towers contributed an average of only 4% to total RF exposure, with LTE levels reaching up to 0.8 volts per meter. All measured exposures remained well below international safety guidelines, though the study focused on regulatory compliance rather than biological effects.

Researchers exposed rabbits to 2.45-GHz microwave radiation (WiFi frequency) to find thermal stress thresholds. When core body temperature rose just 1°C, rabbits showed clear distress behaviors at 1.3 W/kg exposure levels, helping establish microwave safety limits for humans.
Frei P et al. · 2010
Researchers measured 166 people's actual radiofrequency exposure for a week and compared it to common estimation methods used in health studies. People's own estimates of their wireless device usage showed almost no correlation with real exposure levels, while computer models performed much better for accurate health research.

British researchers used computer modeling to calculate how much radiofrequency energy (called SAR) a 10-year-old child's body would absorb from Wi-Fi devices operating at typical household distances. They found that Wi-Fi exposure produced SAR levels of 3.99-5.7 milliwatts per kilogram in the child's torso and head, which is less than 1% of what a cell phone produces. This study provides important baseline data on children's Wi-Fi exposure levels.

Turkish researchers exposed rats to cell phone-like radiation (900 MHz) for 20 minutes daily over three weeks and found significant damage to thyroid glands. The radiation caused thyroid shrinkage, reduced hormone production, and triggered cell death through a process called apoptosis. This suggests that regular exposure to mobile phone radiation could potentially disrupt thyroid function, which controls metabolism and many other vital body processes.
