With the rapid technological advancement the increasing cell phone dependency has led to set up cellular towers in numerous communities. These towers are known as base stations, have antennas and electronic equipment that transmit and receive RF (radio-frequency) signals. Various experimental and epidemiological analysis have been done for searching the potential effect of BTS (Base Transceiver Station) establishment in residential areas and result shows significant health issues, as the RF radiation can mess with the human body’s own EMFs. Therefore, for ensuring public safety it is essential to ascertain the minimum safe distance of establishing BTSs from locality. In this calculation based empirical work, on the basis of SAR (Specific Absorption Rate) mentioned by the World Health Organization, we have analyzed and proposed the minimum reasonable distance of nine major human tissues for being affected by the radiation. This analysis has been done at different frequency bands based on a specific type of antenna at Bangladesh context.
