Aim of study (according to author)
To determine if radiofrequency radiation induces the formation of micronuclei.

Endpoint

• genotoxicity/mutation: formation of micronuclei

Exposure
General category: mobile communication system, CDMA, FDMA

Field characteristics	Parameters
field 1: 835.62 MHz exposure duration: continuous for 3, 8,16, or 24 h FDMA	SAR: 3.2 W/kg mean value (for power setting 1) SAR: 5.1 W/kg mean value (for power setting 2)
field 2: 847.74 MHz exposure duration: continuous for 3, 8,16, or 24 h CDMA	SAR: 3.2 W/kg mean value (for power setting 1) SAR: 4.8 W/kg mean value (for power setting 2)

Exposed system:
intact cell/cell culture (in vitro)
C3H 10T1/2 cells (derived from mouse embryo fibroblasts)

Methods
Endpoint/Measurement parameters/Methodology

• genotoxicity/mutation: formation of micronuclei

Main outcome of study (according to author)
Exposure of C3H10T1/2 cells in exponential growth or in plateauphase to 847.74 MHz CDMA or 835.62 MHz FDMA (at 3.2 W/kg for 24h) did not induce micronuclei.
