Özet
Mobile phones are used by a wide range of people. Even children use mobile phone although they are in high risk group. Because of this, use of mobile phone should be evaluated based on valid and safe information and measurements. We can utilize mobile phone in a way we desire, that is, we can turn it off in order to avoid its radiation when we do not want to use it. However, we cannot control base stations; moreover we do not know where they are mounted. So, radiation of base stations has more importance than that of mobile phones in this respect. Additionally, some GSM service providers may prefer to conceal base station in a way people cannot notice when people are probably opposed to mounting of base station very close to their live space. In this paper, signal strength of base stations (900 MHz) in a pilot region were measured and recorded. The selected region was averagely 500,000 m2 and has 4 base stations. 53 measurement points were determined on the streets of the region. The measurement region had nearly 97 apartments and these apartments had between 400 and 500 flats. The population living in this region was between 1500 and 2000. The averaged signal strength over 53 points in this pilot region were estimated as - 72.7 dBm. The minimum and maximum measurements were recorded as - 87 and - 47 dBm, respectively. The standard deviation of the measurement values was calculated as - 8.5 dBm.
