On exposure-response interpretation and evidence synthesis in low-intensity RF-EMF research
This paper presents a methodological discussion about how to interpret exposure-response patterns and synthesize evidence in low-intensity RF-EMF research, focusing on animal cancer bioassays. It references an exchange around a systematic review on RF-EMF and cancer in experimental animals and critiques/considers approaches to statistical inference and evidence synthesis. The authors emphasize that methodological choices can materially influence carcinogenic hazard identification and argue for rigorous, evidence-based analysis in risk assessment.
Flora and fauna: how nonhuman species interact with natural and man-made EMF at ecosystem levels and public policy recommendations
This PubMed-listed article argues that ambient nonionizing EMF exposures (especially RF-EMF) have increased substantially over the past 60 years and are now pervasive, including from terrestrial networks and low-earth-orbit satellites. It claims these chronic, low-intensity exposures are biologically active and may disrupt critical functions in nonhuman species that rely on geomagnetic cues. The paper discusses nonhuman physiologies and proposes public policy recommendations for wildlife protection, including mitigation and creation of EMF-reduced zones during sensitive periods such as migration and breeding.
Experimental Study of Stress Reactions Induced by Low-Intensity Microwave Radiation
This animal experiment examined hematopoietic and immune-related indicators in mice after repeated exposure to low-intensity microwave radiation. Exposure involved monochromatic pulsed fields in the 2.27–2.78 GHz range with average power flux density of 60 μW/cm² and doses of 0.086–0.86 J/g. The authors report cumulative biological effects consistent with a stress-like adaptive reaction, based on changes in bone marrow, spleen CFU-S measures, erythrocyte hemolytic resistance, and thymus metrics.
Electromagnetic Fields Act Similarly in Plants as in Animals: Probable Activation of Calcium Channels via Their Voltage Sensor
This narrative review proposes that low-intensity microwave/lower-frequency EMFs activate plasma membrane calcium channels in animals, increasing intracellular calcium and triggering downstream signaling including oxidative stress pathways. It further suggests that EMF actions in terrestrial multicellular plants are probably similar, with plant two-pore channels proposed as plausible mediators due to a comparable voltage sensor. The abstract describes briefly reviewed plant studies as consistent with this mechanism, but does not provide detailed exposure parameters or quantitative results.
Headaches from cellular telephones: are they real and what are the implications?
This review discusses reports of headaches occurring with hand-held cellular telephone use and argues they are likely real and attributable to telephone emissions. It points to earlier reports of headaches from low-intensity microwave exposure and proposes biological plausibility via effects on the blood-brain barrier and dopamine-opiate systems. The author raises the possibility that such headaches could signal biologically significant effects.
