In this paper the cooperative electromagnetic pollution index (EMPI) from many RF sources is evaluated in terms of three components which are strength of magnetic and electric field expressed in A/m and V/m, respectively, and irradiated power in W/m 2 . They are generated by a portable laptop computer (LC) with a liquid crystal monitor and other three sources in front area of it. The LC radiation interference with radiation from mobile phone, Wi-Fi and microwave oven in the radio frequency range from 300 Hz up to 3GHz has been measured. The experiment involves testing 45 different points in the keyboard area and 45 points in the in front area of the PC in its operating state. After that a comparison was made between the calculated values for multiple sources frame work and the measured experimental values. Then these EMPI values have been compared with the internationally recommended SAR values.
