Exposure 1

Main characteristics
Frequency 800–900 MHz
Type
Exposure duration continuous for 24, 48 or 96 h
Additional info RF signal modulated according to a GSM signal with a single active slot, that is the transmission frame for the GSM upload
Exposure setup
Exposure source
Setup two wire patch cells, each placed in a Faraday cage inside an CO2 incubator; absorbent material placed along the side walls of the cage; power cable inside the incubator shielded with an aluminum sheet; wire patch cell consisting of two square 15 cm x 15 cm plates, spaced 2.9 cm apart and using four metallic grounding contacts, located at each corner; coaxial cable placed in the center of the wire patch cell that connects the ground plate with the roof plate; E-field with dominant vertical component, polarized in z direction, orthogonal to the metallic plates; H-field with only longitudinal component; cells placed in eight 35 mm (diameter) Petri dishes which were placed in 50 mm diameter dishes in the wire patch cell
Sham exposure A sham exposure was conducted.

Main outcome of study (acc. to author)

The electromagnetic field exposure for 24, 48, and 96 h did not influence the cell viability, cAMP production and iodide accumulation in FRTL- 5 cells compared with controls. The authors conclude that electromagnetic fields under these conditions do not seem to interfere with the biochemical properties of FRTL-5 cells.
