Model		900 MHz (GSM) exposure to residents from base stations and correlation with cancer
Details		Residential proximity to mobile phone base stations was correlated with total cancer incidence. The authors report that preliminary data (1000 individuals) suggests a correlation between general cancer onset and incidence and time living near a mobile phone base station tower. A radius of 400 meters was chosen as the cut-off for the high exposed group with an average distance to buildings within this circle of 266 meters. The average distance to buildings outside the circle was 1076 meters (low exposed group). The transmitter site used for the study has had one antenna operating since September 1993 at 15 watts per channel at a frequency of ~935 MHz (GSM signal), and in 1997 an additional transmitter was installed on the tower by another operator. Exposure was calculated assuming free space characteristics. Spot measurements confirmed a factor of 100 between levels inside and outside the circle. The authors report that for the period of 1999 to 2004, a correlation between high exposure and general cancer incidence was observed (OR = 3.38; 95% CI = 1.39 - 8.25).

Comments		The paper is in German, so it is not clear what the study design was, or even if the paper was peer reviewed. The authors used chi² statistics with a Yates correction to determine an OR = 2.35 (95% CI = 1.18  4.67) for high/low level ratio.
