Experiments were conducted using a dummy phone containing a WCDMA module (average power, 24 dBm at 1950£¿MHz; specific absorption rate, 1.57£¿W/kg) within a headset placed on the head for 32£¿min.WCDMA RF-EMFs generated no physiological changes or subjective symptoms in either group. There was no evidence that EHS subjects perceived RF-EMFs better than non-EHS subjects.Considering the analyzed physiological data, the subjective symptoms surveyed, and the percentages of those who believed they were being exposed, 32£¿min of RF radiation emitted by WCDMA mobile phones demonstrated no effects in either EHS or non-EHS subjects.With the increasing use of third generation (3£¿G) mobile phones, social concerns have arisen concerning the possible health effects of radio frequency-electromagnetic fields (RF-EMFs) emitted by mobile phones in humans [1]. On the basis of limited evidence from both human and animal studies, the World Health Organization has classified RF-EMFs as possibly carcinogenic to humans (Group 2B) [2]. A number of people have self-reported electromagnetic hypersensitivity (EHS), characterized by a variety of non-specific symptoms that differ from individual to individual. Cross-sectional survey studies in different countries have reported that EHS subjects experience non-specific subjective symptoms (e.g., headache, dizziness, fatigue, sleep disorder) associated with EMF exposure: 1.5% in Sweden [3], 3.2% in California [4], and 5% in Switzerland [5]. For some individuals, the symptoms can have lifestyle-changing consequences [6].Although numerous studies have examined the effects of Global System for Mobile Communications (GSM) on humans between EHS and non-EHS groups, o %K Provocation %K Physiological changes %K HRV %K Subjective symptoms %K EMF perception %U http://www.ehjournal.net/content/11/1/69
