Thanks to the technology, mobile devices including cell phones have become an integral part of the modern life. Therefore, public concern pertaining to short-term and long-term possible adverse effects of using cell phone and electromagnetic radiation exposure of it is growing rapidly. There are various studies by which the positive and negative results have been demonstrated. The relationship ...
Introduction: The great use of electrical appliances in different life applications is one of the most obvious concerns because of its possible health drawbacks. These investigation reports results of electromagnetic field effect emitted from mobile phones on some biophysical parameters of human blood belonging to blood groups A, B, AB & O collected from the normal persons. The parameters obser...
background: pre-exposure to radiofrequency radiations of mobile phones would significantly increase the survival rate of exposed animals compared to those exposed to a lethal dose of gamma radiation alone. stimulation of the immune system is believed to be a key mechanism for the induction of this phenomenon, the so-called “adaptive response.” the immune system protects organisms against infect...
a study on the frequency and type of using cell-phone by high school students in mazandaran province
this study aimed at the frequency and type of using cell-phone by high school students. the research method used was a descriptive-survey one. the statistical society included all the high school students in mazandran in 2010-11 academic year. the sample was chosen through multi-stage stratified random sampling method and 383 subjects were selected based on kerjecie and morgan's table. a r...
Background & Aims: Mobile phone radiation is a major public health concern. This study aimed to determine if a quantitive relation could be found between specific absorption rate (SAR) and salivary volume and C-reactive protein (CRP) Material & Methods:Unstimulated whole salivary samples of 310 mobile phone users were collected. Mobile phones were categorized into three groups according to t...
Introduction:Using cell phone has become an inseparable part of the life in the recent years. In spite of the useful usage of the cell phone, its constant over-use makes the field for people’s addiction and harms. The purpose of the present research is to analyze the relation between the cell phone’s scale and the way of use with the motivation of educational progress among the female students’...
With an ever increasing number of cell phone users since late twentieth [corrected] century, magnitude of the problem of exposure to radiation emitted by cell phone is self evident. Extensive research had been devoted to incriminate or absolve it as a health hazard. Radiofrequency radiation emitted by cell phone had been stated to be a potent carcinogen, cytotoxic, genotoxic, mutagenic and neur...
Background: There is a great concern for the possible adverse effects of cell phones’ microwaves. Contradictory results, however, have been reported for the effects of these waves on the body. In the present study, the effect of cell phone microwaves on sperm parameters and total antioxidant capacity was investigated with regard to the duration of exposure and the amount of the frequency of the...
to date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 mhz microwave radiation, originating from the handsets or the base transceiver stations, have been released. the current study was designed for evaluation of 900-mhz radiation effects on candida albicans proliferatio...
