Jan 1, 2026
This chronic animal bioassay assessed carcinogenicity and genotoxicity of CDMA-modulated 900 MHz RF exposure at a whole-body SAR of 4 W/kg using a shared Korea–Japan protocol. Male Sprague-Dawley rats were exposed starting on gestational day 5 with daily intermittent exposure for long durations, including a 2-year…
Radio Frequency Exposure in Military Contexts: A Narrative Review of Thermal Effects and Safety Considerations
Research
RF Safe Research Library
Jan 1, 2025
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…

Jan 1, 2025
This magazine article reviews the Japan-Korea "NTP Lite" RF animal toxicity collaboration and its relationship to prior NTP (2018) and Ramazzini Institute reports of RF-associated tumors in male rats. It notes NTP Lite used a single whole-body SAR of 4 W/kg and completed a two-year exposure phase in 2022, but final…

Jan 1, 2025
This study uses anatomically detailed computational models of a five-year-old girl, a pregnant woman in the third trimester, and a fetus to simulate mobile phone RF exposure inside an elevator cabin. Simulations at 1000 MHz and 1800 MHz across 48 configurations evaluated SAR10g, whole-body SAR, and maximum…
Characterization of the Core Temperature Response of Free-Moving Rats to 1.95 GHz Electromagnetic Fields

RF Safe Research Library
Jan 1, 2025
This animal study measured core body temperature in free-moving male and female Sprague Dawley rats during and after 3-hour exposure to 1.95 GHz RF-EMF at multiple whole-body average SAR levels. A measurable thermal response was reported at 4 W/kg, while lower SAR conditions showed smaller or no significant…
Assessment of RF EMF Exposure to Car Driver from Monopole Array Antennas in V2V Communications Considering Thermal Characteristics

Jan 1, 2025
This modeling study assessed RF-EMF exposure from a 5.9 GHz V2V monopole array antenna integrated into a car roof shark-fin antenna. Using COMSOL simulations with an adult male body model inside a vehicle, the authors estimated localized and whole-body SAR and associated core temperature rise over a 30 min averaging…
Effect of Exposure to a Radiofrequency Electromagnetic Field on Body Temperature in Anesthetized and Non-Anesthetized Rats.

Jan 1, 2020
This animal study examined whether anesthesia and body mass modify body temperature responses to 915 MHz RF exposure at 4 W/kg whole-body SAR for 8 hours. Non-anesthetized, free-moving rats showed no significant temperature change during exposure. In contrast, anesthetized rats showed marked temperature increases,…
The specific absorption rate in different brain regions of rats exposed to electromagnetic plane waves.

Jan 1, 2019
This study develops a numerical voxel rat model with 10 segmented brain regions to evaluate region-specific dosimetry under plane-wave EMF exposure. It reports that brain-region averaged SAR varies with frequency, incidence direction, and E-polarization direction. The authors also report potentially large deviations…
