Exposure details

Radiofrequency radiation at 1950 MHz (UMTS) does not affect key cellular endpoints in neuron-like PC12 cells.

Exposure 1:
Main characteristics frequency: 1950 MHz type of field: electromagnetic field add. information: UMTS uplink frequency Modulation type of modulation: WCDMA	Exposure setup exposure source/structure: waveguide exposure time pattern: continuous for 24 h chamber details: two exposure chambers of rectangular waveguides (WR 430, 350 mm) housed (together with sham waveguide) in commercial incubator; waveguides fed by amplified signal of a signal generator setup details: samples placed on four-layer plexiglass stand with 35 mm Petri dishes on each layer; center of samples located 0.56 λ from short circuit (λ = waveguide wavelength); circulating water jacket maintained the temperature constant at 36.8°C sham: sham exposure was performed
Exposure parameters parameter: value: type: method: remark: SAR  10 W/kg  mean value  measured and calculated  -  measurement and calculation details: RF simulated with a rectangular waveguide (inner transversal dimensions: 109.2 mm x 54.6 mm); condition of an empty waveguide achieved by keeping the longitudinal axis and the narrow side of the waveguide horizontal
