Assessment of spatial-average absorbed power density and peak temperature rise in skin model under localized electromagnetic exposure

Research RF Safe Research Library Jan 1, 2025

This numerical dosimetry study modeled localized RF exposure (3–30 GHz) in multi-layer human skin constructs including skin, fat, and muscle, with an added synthetic blood vessel model. Vascular modeling had negligible impact on peak spatial-averaged absorbed power density and a modest impact on peak temperature rise…

Evidences of the (400 MHz - 3 GHz) radiofrequency electromagnetic field influence on brain tumor induction.

Research RF Safe Research Library Jan 1, 2022

This review discusses whether radiofrequency electromagnetic fields (400 MHz–3 GHz), particularly from mobile phones, influence brain tumor induction. The abstract describes epidemiological evidence as supporting a causal association, highlighting statistically significant ipsilateral tumor findings. It also claims…

A statistical analysis for RF-EMF exposure levels in sensitive land use: A novel study in Greek primary and secondary education schools.

Research RF Safe Research Library Jan 1, 2020

This exposure assessment estimated mean RF-EMF levels in Greek primary and secondary schools located in urban environments. Using a random sample of 492 schools, the reported mean electric field strength across 27 MHz–3 GHz was 0.42 V/m with a 95% CI of 0.4024–0.4395 V/m. The authors conclude the measured levels were…

RF-EMF EXPOSURE LEVELS IN SENSITIVE LAND USE IN GREECE: EDUCATIONAL UNITS CENSUS IN THE MUNICIPALITY OF KORYDALLOS.

Research RF Safe Research Library Jan 1, 2020

This exposure assessment measured RF-EMF levels in all primary and secondary school units (n=62) in Korydallos, Athens, across 27 MHz–3 GHz. The study reports that 97.5% of schools had exposure levels at least 2200 times below Greek exposure limits. The authors conclude the measured levels were below 60% of the…

Exposure assessment of radio frequency electromagnetic field levels in hospitals of Samsun Province, Turkey.

Research RF Safe Research Library Jan 1, 2020

This exposure assessment measured RF-EMF levels in 21 state hospitals in Samsun Province, Turkey using short-term, long-term, and band-selective approaches across 100 kHz–3 GHz (total) and 27 MHz–3 GHz (band-selective). The study reports that the ICTA 3 V/m limit was exceeded in at least some hospital measurements,…

Long-Term Study on the Effects of Housing C57BL/6NCrl Mice in Cages Equipped With Wireless Technology Generating Extremely Low-Intensity Electromagnetic Fields.

Research RF Safe Research Library Jan 1, 2019

This animal study characterized electromagnetic fields generated by digitally ventilated mouse cages with wireless monitoring technology and assessed clinicopathological outcomes over up to 1 year. DVC produced extremely low-intensity electric fields across a wide frequency range (5 Hz to 3 GHz). The authors report…

Citrate-capped gold nanoparticle electrophoretic heat production in response to a time-varying radiofrequency electric-field.

Research RF Safe Research Library Jan 1, 2012

This in vitro study examines RF-induced heat production in citrate-capped gold nanoparticle suspensions while minimizing confounding Joule heating from ionic buffers. It reports size-dependent heating detectable only for ≤10 nm particles, with heating scaling with concentration and surface area and being attenuated…

[Assessment of radiofrequency electromagnetic fields levels in the Taranto area].

Research RF Safe Research Library Jan 1, 2007

This study reports punctual monitoring of RF electromagnetic fields from radiobase stations in the Taranto area, with measurement campaigns conducted from November 2005 to March 2007. Measurements covered 108 transmitting stations across multiple communication technologies within 100 kHz to 3 GHz. Most monitored…
