Bio- Thermal Effects due to Electromagnetic Radiation

Possible temperature changes in human body exposed to the radiation emitted from radio/TV/Microwave communication transmitter is evaluated. The process uses (i) propagation from transmitter, field value reducing inversely with distance (ii) penetration into a human body, field reducing exponentially with depth (iii) absorption of power, specific absorption rate (SAR) being proportional to the conductivity and square of the field value and inverse of material density (iv) temperature rise proportional to SAR and inverse to the specific heat of the body material. The results show the sufficient temperature rise to recommend the minimum distance of the transmitters from the populated areas
