ID Number 1099
Study Type Epidemiology
Model 900, 1800 MHz (GSM) mobile phone use in Italy and exposure assessment for epidemiologic studies
Details

Software modified phones (SMPs as used in the INTERPHONE dose verification study, models from Alcatel, Ericsson, Motorola, and Nokia) were used by 12 volunteers in Italy (location undefined). The authors report that despite dynamic power control a large proportion of recorded phone usage took place at or near maximal power levels (when on a 900-MHz network the phones operated at max power 58% of the time, on the 1800 MHz network they operated at max power 38% of the time). For the entire study, the average power output was 167 mW for 900 MHz phones and 63 mW for 1800 MHz phones (67 and 50 percent of maximum output, respectively). The authors also report average power output substantially higher when moving in a vehicle or indoors. In a subsequent paper (2006), however, the authors report higher mobile phone output power in rural vs urban areas and other factors (length of call, moving/stationary, indoor/outdoor) were of less importance.

    Because of the low number of samples, and unclear data regarding where the calls were actually made, results could have been skewed if only one or two volunteers spent considerable time (or made frequent calls from) an area with poorer than average coverage.
