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,…

The influence of electromagnetic fields generated by wireless connectivity systems on the occurrence of emotional disorders in women: A preliminary report.

Research RF Safe Research Library Jan 1, 2019

This preliminary cross-sectional study of 200 women working in healthcare and trade assessed associations between wireless-system EMF exposures and emotional disorders. The authors report that GSM 900/1800 base-station exposure contributed to depressive disorders among medical personnel, while WLAN exposure was…

Effect of short exposure to radiofrequency electromagnetic fields on saliva biomarkers: a study on the electrohypersensitive individuals.

Research RF Safe Research Library Jan 1, 2019

This double-blind provocation study examined whether short RF-EMF exposure alters salivary biomarkers in electrohypersensitive (EHS) individuals. Ten participants underwent sham and real exposure sessions with consecutive GSM 900, GSM 1800, DECT, and Wi‑Fi signals for 5 minutes each. The study reports no significant…

No influence of acute RF exposure (GSM-900, GSM-1800, and UMTS) on mouse retinal ganglion cell responses under constant temperature conditions.

Research RF Safe Research Library Jan 1, 2014

This double-blind in vitro study exposed isolated mouse retinae to GSM-900, GSM-1800, and UMTS RF-EMF at SARs up to 20 W/kg while maintaining constant temperature. Changes in retinal ganglion cell responses to light stimuli were compared before, during, and up to 35 minutes after exposure. The authors report no…
