Review: Weak radiofrequency radiation exposure from mobile phone radiation on plants.

Halgamuge MN. · 2017

Researchers analyzed 45 studies examining how radiofrequency radiation from mobile phones affects plants, looking at 169 experiments across 29 plant species. They found that nearly 90% of studies showed biological effects in plants exposed to cell phone frequencies, with certain crops like corn, tomatoes, and peas appearing especially sensitive. This suggests that the wireless radiation we consider safe may be causing measurable biological changes in living organisms.

Electromagnetic Field Exposure Changes Due to the Digital Television Switchover in Thessaloniki, Greece.

Gkonis F, Boursianis A, Samaras T. · 2017

Researchers measured electromagnetic field exposure from television broadcasts in Thessaloniki, Greece, before and after the transition from analog to digital TV. They found that digital television signals produced 78% lower power density (13.3 μW/m²) compared to analog broadcasts (60 μW/m²). This means the digital switchover significantly reduced the population's exposure to radiofrequency radiation in the UHF television band.

Effects of radiofrequency exposure emitted from a GSM mobile phone on proliferation, differentiation, and apoptosis of neural stem cells.

Eghlidospour M, Ghanbari A, Mortazavi SMJ, Azari H. · 2017

Iranian researchers exposed neural stem cells (brain cells that can develop into neurons) to radiation from a GSM 900-MHz mobile phone for different time periods. They found that longer exposures significantly reduced the cells' ability to multiply and form new neurons, though the cells didn't die. This suggests that cell phone radiation may interfere with the brain's natural ability to generate new brain cells, a process crucial for learning, memory, and brain repair.

Mobile phone use, school electromagnetic field levels and related symptoms: a cross-sectional survey among 2150 high school students in Izmir.

Durusoy R, Hassoy H, Özkurt A, Karababa AO. · 2017

Turkish researchers surveyed 2,150 high school students about their mobile phone use and measured electromagnetic field levels in their schools. Students who used mobile phones were 90% more likely to experience headaches, 78% more likely to report fatigue, and 53% more likely to have sleep problems compared to non-users. The study found clear dose-response relationships, meaning heavier phone use correlated with more frequent symptoms.

Is mobile phone radiation genotoxic? An analysis of micronucleus frequency in exfoliated buccal cells.

de Oliveira FM, Carmona AM2 Ladeira C. · 2017

Researchers examined cheek cells from 86 mobile phone users to see if phone radiation causes micronuclei (tiny fragments that indicate DNA damage). They found no difference in DNA damage between the side of the mouth where people held their phones versus the opposite side, and no relationship between daily phone use duration and genetic damage.

A study on the effect of prolonged mobile phone use on pure tone audiometry thresholds of medical students of Sikkim.

Das S, Chakraborty S, Mahanta B. · 2017

Researchers tested the hearing of medical students who had been using mobile phones for at least 5 years, comparing the ear they typically hold their phone to versus their other ear. They found measurable hearing loss in the phone-exposed ear at high frequencies (2, 4, and 8 kHz), with both air and bone conduction thresholds significantly elevated compared to the unexposed ear. This suggests that regular mobile phone use may gradually damage hearing, particularly at frequencies important for understanding speech.

The response of human bacteria to static magnetic field and radiofrequency electromagnetic field.

Crabtree DPE, Herrera BJ, Kang S. · 2017

Researchers at Baylor University exposed bacteria from human skin to radiofrequency electromagnetic fields (the type emitted by cell phones) and found that these exposures altered bacterial growth patterns. The study tested both laboratory bacteria and skin bacteria samples from people with different cell phone usage histories, finding variable but consistent disruption across different bacterial species. This suggests that cell phone radiation may be disrupting the beneficial bacteria that naturally live on our skin, potentially affecting human health through this disrupted relationship.

Maternal cell phone use during pregnancy and child behavioral problems in five birth cohorts.

Birks L et al. · 2017

Researchers analyzed data from 83,884 mother-child pairs across five countries to examine whether cell phone use during pregnancy affects children's behavior. They found that mothers who used cell phones more frequently during pregnancy were more likely to have children with hyperactivity and attention problems by ages 5-7. The study suggests prenatal EMF exposure may influence brain development, though the researchers acknowledge other factors could explain these connections.

Use of mobile and cordless phones and change in cognitive function: a prospective cohort analysis of Australian primary school children.

Bhatt CR et al. · 2017

Australian researchers followed 412 primary school children for up to 3 years to see if using mobile phones and cordless phones affected their thinking abilities. They found mixed results - increased mobile phone use was linked to some changes in cognitive performance, including faster response times on some tasks but slower response times on others. The researchers concluded there was limited evidence that phone use significantly impacts children's cognitive function.

Long-term exposure to a continuous 900 MHz electromagnetic field disrupts cerebellar morphology in young adult male rats.

Aslan A, İkinci A, Baş O, Sönmez OF, Kaya H, Odacı E. · 2017

Researchers exposed young rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during adolescence and examined their brain tissue. They found significant damage to the cerebellum, including fewer Purkinje cells (critical neurons for movement and coordination) and abnormal cell arrangement in exposed animals compared to unexposed controls. This suggests that even brief daily EMF exposure during brain development may cause lasting neurological damage.

Assessment of long-term spatio-temporal radiofrequency electromagnetic field exposure.

Aerts S, Wiart J, Martens L, Joseph W. · 2017

Researchers tracked radiofrequency radiation levels from cell phone towers across an urban area for over a year using a network of measurement devices. They found that RF exposure levels varied dramatically - up to 12,000 times higher at some locations and times compared to others, even though there was no overall trend of increasing or decreasing exposure. This variation followed daily and weekly patterns that could be predicted with 50% better accuracy when time factors were included in exposure models.

Occupational exposure and amyotrophic lateral sclerosis in a prospective cohort.

Koeman T et al. · 2017

Researchers followed over 120,000 Dutch adults for 17 years to study whether workplace exposures increase the risk of ALS (amyotrophic lateral sclerosis), a fatal neurological disease. Men with high occupational exposure to extremely low frequency magnetic fields (ELF-MF) had more than double the risk of dying from ALS compared to those with background exposure. This adds to growing evidence that ELF-MF exposure may contribute to this devastating disease that affects nerve cells controlling voluntary muscles.

Anxiety-like behavioural effects of extremely low-frequency electromagnetic field in rats.

Djordjevic NZ, Paunović MG, Peulić AS. · 2017

Researchers exposed rats to 50 Hz electromagnetic fields (the same frequency as household electricity) for seven days and found it caused anxiety-like behaviors. The EMF exposure increased harmful oxidative stress compounds in the brain region that controls stress responses. This suggests that common power line frequencies may directly affect brain chemistry and emotional well-being.

Dopamine-dependent changes of cortical excitability induced by transcranial static magnetic field stimulation in Parkinson's disease.

Dileone M et al. · 2017

Researchers tested how static magnetic fields affect brain activity in Parkinson's disease patients by applying magnetic stimulation to the motor cortex for 10 minutes. They found that the magnetic fields reduced brain excitability when patients were off their dopamine medications, but had no effect (or even opposite effects) when patients were on medication. This suggests that magnetic field effects on the brain depend heavily on dopamine levels and disease progression.

Impact of radiofrequency radiation on DNA damage and antioxidants in peripheral blood lymphocytes of humans residing in the vicinity of mobile phone base stations.

Zothansiama, Zosangzuali M, Lalramdinpuii M, Jagetia GC. · 2017

Researchers studied 40 people living within 80 meters of cell phone towers and compared them to controls living 300 meters away. They found that those closer to towers had significantly more DNA damage in their blood cells and reduced levels of protective antioxidants like glutathione, catalase, and superoxide dismutase. This suggests that chronic exposure to radiofrequency radiation from cell towers may compromise the body's natural defenses against cellular damage.

Radiofrequency electromagnetic radiation from cell phone causes defective testicular function in male Wistar rats.

Oyewopo AO, Olaniyi SK, Oyewopo CI, Jimoh AT. · 2017

Researchers exposed male rats to cell phone radiation for 1-3 hours daily over 28 days and found significant damage to reproductive function. The radiation caused cellular degeneration in testicles, increased harmful oxidative stress, and decreased key reproductive hormones including testosterone. This suggests that regular cell phone exposure may impair male fertility through biological mechanisms that worsen with longer exposure times.

Effects of repeated restraint stress and WiFi signal exposure on behavior and oxidative stress in rats.

Othman H, Ammari M , Sakly M, Abdelmelek H. · 2017

Researchers exposed rats to WiFi signals for 2 hours daily over 20 days, with some rats also experiencing stress. WiFi exposure increased anxiety-like behavior and caused oxidative stress (cellular damage from free radicals) in the brain, with effects becoming worse when combined with stress. The study suggests that everyday WiFi exposure may affect brain chemistry and behavior, particularly in stressful situations.

Phenotypic and genotypic characterization of antioxidant enzyme system in human population exposed to radiation from mobile towers.

Gulati S, Yadav A, Kumar N, Priya K, Aggarwal NK, Gupta R. · 2017

Researchers studied people living near cell phone towers to measure their body's antioxidant defenses - the natural systems that protect cells from damage. They found that people exposed to tower radiation had significantly weaker antioxidant enzyme activity and more cellular damage markers compared to unexposed individuals. The study also revealed that certain genetic variations made some people more vulnerable to this radiation-induced damage.

Extremely low frequency pulsed electromagnetic fields cause antioxidative defense mechanisms in human osteoblasts via induction of •O2 − and H2O2

Ehnert S et al. · 2017

German researchers exposed human bone cells to extremely low frequency electromagnetic fields (16 Hz) for 7 minutes daily over 5 days to study cellular responses. They found that single exposures triggered oxidative stress, but repeated exposures actually strengthened the cells' antioxidant defenses and improved bone formation. The study suggests these electromagnetic fields might help bone healing by training cells to better handle oxidative damage.

Effects of short and long term electromagnetic fields exposure on the human hippocampus

Deniz OG et al. · 2017

Researchers compared brain scans and cognitive tests between female medical students who used mobile phones less than 30 minutes daily versus those using them more than 90 minutes daily. While brain structure appeared unchanged, the heavy phone users performed significantly worse on attention and concentration tests. This suggests that regular mobile phone use may impair cognitive function even in young, healthy adults.

Mitochondrial DNA damage and oxidative damage in HL-60 cells exposed to 900MHz radiofrequency fields.

Sun Y, Zong L, Gao Z, Zhu S, Tong J, Cao Y · 2017

Researchers exposed human blood cells to 900MHz radiofrequency radiation (the same frequency used in many cell phones) for 4 hours daily over 5 days. The radiation caused significant damage to mitochondrial DNA (the genetic material in cellular powerhouses) and increased harmful free radicals, while reducing the cells' ability to produce energy. Importantly, treating the cells with melatonin, a natural antioxidant, prevented this damage.

Mobile-phone Radiation-induced Perturbation of Gene-expression Profiling, Redox Equilibrium and Sporadic-apoptosis Control in the Ovary of Drosophila melanogaster

Manta AK et al. · 2017

Researchers exposed fruit flies to mobile phone radiation for just 30 minutes and found it triggered a cascade of harmful cellular changes in their ovaries. The exposure increased damaging molecules called reactive oxygen species by 60%, altered the activity of 168 genes, and doubled the rate of cell death within hours. This demonstrates that brief mobile phone exposure can disrupt fundamental biological processes at the cellular level.
