Mobile Phone Radiation

Background: The usage of mobile phone had been increased drastically which created a major health concern among the people about the radiation emitted from mobile phones. Hence this study was aimed to evaluate the Micronuclei (MN) frequency in exfoliated oral mucosal cells in high and low mobile users based on Specific absorption rate (SAR) value.Methods: The total of 60 subjects were divided into two major groups: low SAR mobile phone users and high SAR mobile phone users. Further, Subjects who use mobile phone for more than 3 hours a week was considered as high talk time users and less than 3 hours a week was low talk time users. The buccal mucosa cells extracted by slightly scraping the oral cavity with a wooden spatula. For staining, Giemsa stain was used. Micronuclei were evaluated in 1000 cells per individual at the microscope.Results: The result show prolonged talk time may interfere with the development of micronuclei in individuals who use mobile phone for more than 3 hours per week rather than high SAR value showing a significant increase in frequency of micronuclei formation.Conclusions: The study showed mobile phone radiation had adverse effects on buccal mucosal cells.

Mobile Phone Radiation

The human head is one of the most sensitive parts of the human entire body when exposed to electromagnetic radiation. This electromagnetic radiation interacts with the human head and may lead to detrimental effects on human health. However, the resulting thermophysiologic response of the human head is not well understood. In order to gain insight into the phenomena occurring within the human head with temperature distribution induced by electromagnetic field, a detailed knowledge of absorbed power distribution as well as temperature distribution is necessary. This study presents a numerical analysis of specific absorption rate and heat transfer in the heterogeneous human head model exposed to mobile phone radiation. In the heterogeneous human head model, the effects of user age and radiated power on distributions of specific absorption rate and temperature profile within the human head are systematically investigated. This study focuses attention on organs in the human head in order to investigate the effects of mobile phone radiation on the human head. The specific absorption rate and the temperature distribution obtained by numerical solution of electromagnetic wave propagation and unsteady bioheat transfer equation in various tissues in the human head during exposure to mobile phone radiation are presented.

The People

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.

The interaction of a mobile antenna and a passenger is analyzed inside a metallic enclosure. The specific absorption rate (SAR) of the passenger in the elevator using a mobile phone is calculated. A standardized model of human head is filled with liquid that simulates the RF absorption characteristics. The non-uniform mesh technique in frequency domain is employed to obtain 1g SAR [Specific Absorption Rate] and other important parameters. The mobile phone is modeled as a quarter wavelength Planar Inverted F Antenna (PIFA), and it is of .01m from the head. PIFA is operated at frequencies of 900 and 1800MHz with transmitting power .3 W . It is observed that the values of SAR inside the metallic enclosure exceeds the RF safety limits. Therefore, this project proposes a novel method to reduce the SAR by using carbon foam which absorbs microwave radiation. Simulated results have evidenced the efficiency of the proposed technique of SAR reduction inside the enclosures.
