In this work, a numerical calculation was carried out in one of the universal programs for automatic electro-dynamic design. The is aimed at obtaining values specific absorbed power (SAR). It SAR value that can be used to determine effect antenna wireless device on biological objects; dipole parameters will selected GSM1800. Investigation influence distance cell phone radiation shows head perso...

Objective(s): The increasing rate of over using cell phones has been considerable in youths and pregnant women. We examined the effect of mobile phones radiation on genes expression variation on cerebellum of BALB/c mice before and after of the birth. Materials and Methods: In this study, amobile phone jammer, which is an instrument to prevent receiving signals between cellular phonesand base t...

BACKGROUND The association between cell phone use and the development of parotid tumors is controversial. Because there is unequivocal evidence that the microenvironment is important for tumor formation, we investigated in the parotid glands whether cell phone use alters the expression of gene products related to cellular stress. METHODS We used the saliva produced by the parotid glands of 62...

The radiofrequency electromagnetic fields (RF-EMFs) produced by widely used mobile phones are classified as possibly carcinogenic to humans by International Agency for Research on Cancer (IARC). Current data on the relationship between exposure to RF-EMFs generated by commercial mobile phones and brain cancer are controversial. Our studies show that this controversy may be caused by several par...

This study aimed to investigate whether third generation mobile phone radiation peaks result in event related potentials. Thirty-one healthy females participated. In this single-blind, cross-over design, a 15 minute mobile phone exposure was compared to two 15 minute sham phone conditions, one preceding and one following the exposure condition. Each participant was measured on two separate days...

Background: We have earlier shown that exposure of human endothelial cell line EA.hy926 to 900 MHz GSM mobile phone radiation causes changes in the expression of numerous proteins. Here, we have examined the effects of 1800 MHz GSM mobile phone signal on the proteome of the same cell line. Results: EA.hy926 cells were exposed for one hour to 1800 MHz GSM signal, simulating mobile phone talking ...

BACKGROUND The incidence rates of differentiated thyroid cancers of all sizes increased between 1988 and 2005 in both men and women. Exposure to ionizing radiation is the best-established environmental risk factor for thyroid cancer. Nonionizing radiation from cell phones has also been implicated. A positive correlation between all-cancer incidence rates and latitude and an inverse correlation ...

New technologies are evolving day to day life to facilitate human being. Mobile communication is currently the fastest growing communication system in the telecommunication industry. Due to the increased number of users using the mobile phone, the concern is now focused towards electromagnetic radiations emitted by the mobile phones itself. Electromagnetic radiation can be classified into ioniz...
