The researches realized on the biological effects of Electromagnetic Radiation (EMR) highlighted that the exposure of the human factor on the electromagnetic radiations of high frequency determines an excessive heating of the tissue causing different burning types. The aim of this paper is to analyze, by comparison, the effect of heating of the facial tissue under the Electromagnetic Radiation (EMR) influence provided from two mobile phones with different Specific Absorption Rate (SAR) index. Helping with the thermal maps, it determined the heating level of the human tissue exposed under the EMR generated by the phone during the conversation. The results obtained after the analysis are very useful for the evaluation of the heating level of the facial tissue in function of the SAR absorption index of the phone

Daily use of wireless devices, especially mobile phones, has caused great concern among the public about the possible health effects of electromagnetic radiation to which the users of these devices, primarily children, are exposed. This paper summarizes the habit of using mobile phones by children and teenagers and its connection with possible harmful biological effects of electromagnetic radiation of these devices. This paper describes the procedure of creating models of adult and child heads that are used for numerical calculation of electromagnetic field penetration and the absorbed energy. As we know, the human body consists of many different tissues and organs, so each of them needs to be described by the appropriate electromagnetic characteristics. Key words: mobile phone, electromagnetic characteristics of tissues, model of child head, specific absorption rate

On a global scale, the telecommunication industry is experiencing tremendous growth in mobile phones. Mobile phones communicate with base stations that are erected by the telecommunication industry. The base station produces radio frequency and exposes the people near the base stations to radiation. The effect of electromagnetic radiation from four base stations located at the residential area was studied by measuring their electric field strength and calculating their magnetic field strength and power density at different distances covering a frequency range of 900MHz to 2100MHz. The obtained values showed that the four cellular base stations are operating above the standard values of the International Commission on Non-Ionizing Radiation Protection Electromagnetic Field Radiation. The specific absorption rate was measured to determine the amount of radio frequency electromagnetic radiation absorbed by the human body. The result which is in the range of 3.22-3.70 W/kg is higher than the acceptable 2 W/kg for localized specific absorption rate.

This paper describes the various aspects of biological effects of high frequency electromagnetic fields on the human body. Specific Absorption Rate in human model by the IEC62209-1 standard is simulated and evaluated. Also the effect of change in physical parameter on Specific Absorption Rate is simulated and compared by IEC standard model. High Frequency Field Simulation Structure software has been used for simulations.


in fast growing world Mobile phone has become part of the human life. Specific Absorption is a measurement for the amount of Electromagnetic energy that has been absorbed by human tissue ,. Electromagnetic Radiation associated with Mobile Phones is always as an issue that has to be addressed for human safety, Particularly for children. More focus has been paid to induced SAR in the human head when exposed to EM Waves emitted from mobile Phone Antenna, but while using mobile phone the user gets exposed to a dangerous electromagnetic Radiations. ICNIRP Prescribed some guidelines for EM Exposure Level for Public. The Present paper is discuss the SAR Values of different Mobile Phones, Measured How much People are Aware of SAR Values are given as a survey. The study is compromised individuals that visited in the survey site .The awareness is assessed using structured questions and it was recorded to measure the awareness.
