This exposure assessment measured outdoor micro-environment RF-EMF levels in daily-life settings across urban and suburban locations in Japan using a portable device (50 MHz–6 GHz) with GPS. Reported exposure levels were higher in urban areas, with railway stations showing the highest levels among the environments measured. The authors emphasize the need for further comprehensive studies and frame prolonged RF-EMF exposure as an ongoing public health concern.
Radio Frequency Exposure in Military Contexts: A Narrative Review of Thermal Effects and Safety Considerations
This narrative review focuses on RF exposure in military contexts, emphasizing thermal effects as the established mechanism of harm and discussing safety limits set by bodies such as ICNIRP and IEEE. It reports that whole-body SAR limits (≤4 W/kg) generally prevent dangerous core temperature rises, but localized heating risks may persist for tissues like skin and eyes, especially when thermoregulation is impaired. The review highlights CEM43 as a potentially useful thermal-dose metric but notes complexity for transient exposures and calls for improved models and methods across relevant frequency bands.
Combined effects of constant temperature and radio frequency exposure on Aedes mosquito development
This laboratory study tested combined effects of constant temperature and RF exposure on development of Aedes aegypti and Aedes albopictus from hatching to adult emergence. Temperature was reported as the primary determinant of developmental timing, with optimal development around 30 2 C. RF exposure (900 MHz and 18 GHz) was described as a secondary factor that could accelerate or prolong development depending on temperature, with synergistic shortening at 25 0 C and prolongation under suboptimal conditions.
Toxicology and carcinogenesis studies in Sprague Dawley (Hsd:Sprague Dawley SD) rats exposed to whole-body radio frequency radiation at a frequency (900 MHz) and modulations (GSM and CDMA) used by cell phones
This National Toxicology Program technical report describes 900 MHz whole-body RFR exposures (GSM and CDMA) in male and female Sprague Dawley rats from in utero through up to 2 years. The report concludes clear evidence of carcinogenic activity in males for both modulations based on malignant schwannoma of the heart, with malignant glioma of the brain also reported as related to exposure. In females, the report concludes equivocal evidence of carcinogenic activity for both modulations based on selected tumor outcomes, and genetic toxicology findings were mixed with some comet assay increases/equivocal results but negative micronucleus assays.
