Mobile phones are low-powered radiofrequency transmitters, operating at frequencies between 450 and 2700 MHz with peak powers in the range of 0.1 to 2 watts. The handset only transmits power when it is turned on. The power (and hence the radiofrequency exposure to a user) falls off rapidly with … Meer weergeven A large number of studies have been performed over the last two decades to assess whether mobile phones pose a potential … Meer weergeven Radiofrequency exposure limits for mobile phone users are given in terms of Specific Absorption Rate (SAR) – the rate of radiofrequency energy absorption per unit mass of the body. Currently, two international … Meer weergeven In response to public and governmental concern, WHO established the International Electromagnetic Fields (EMF) Project in 1996 to assess the scientific evidence of … Meer weergeven WebThe microwave frequencies utilized in mobile communication cause thermal and non-thermal effects and leave a negative impact on the biological system. The quantity of RF-EMW radiation energy absorbed by human tissue depends on the frequency, intensity, polarization, and period of exposure.
