Many people are not aware of the harmful effects of radiofrequency waves (RF) and their role in cancer and other serious risks. Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1). Many scientific studies have been done on the radiobiological effects of RF waves, and most of them have reported the rare relationship between RF exposure and risks posed by mobile phones on the body in the last 15 years (2). However, they could lead to increased body temperature, especially in the head and neck, who have a low threshold dose and increases the probability of injury if there is long-term exposure to these waves. Mobile phones emit RF waves even when they are in standby mode. When using mobile phones, various factors should be considered, such as the duration, location, and method of use, in order to reduce the possible effects of exposure to radiation in the RF. Because of the risk of mutation and sexual trauma and to prevent infertility due to the effect on male sexual cells, the mobile phone should be away from the waist. In this study, we measured the emitted dose from a radiofrequency device at different frequencies using a scintillation detector. The results of this study and International Commission of Non Ionization Radiation Protection (ICNIRP) reports show that people who use cell phones more than 50 minutes a day face early dementia or other thermal damage due to the burning of glucose in the brain (3). Currently, the ranges of subjects related to occupational and public exposure of electromagnetic fields have been increased. Due to the possibility of adverse effects on human health, performance study of these devices has significant importance (4). There are two types of electromagnetic fields based on the frequency range, i.e., extremely low frequency (ELF) and very low frequency (VLF) fields. ELF and VLF fields frequency ranges are between 3 and 300 Hz and 3 and 300 kHz, respectively. Due to the nature of static electricity, electric and magnetic fields at these frequencies operate separately from each other and will be measured in the different circumstances (5). Electric and magnetic fields can be produced by carrying of electric current at any wiring or equipment, such as overhead or underground power lines, home wiring, medical equipment, and electronic devices (6). The most important factors that influence human exposure are power density of the frequency generator source, distance from the source, type and thickness of the exposed beams, and frequency (penetrated depth) of the RF input signal to the body (7). Figure 1 shows the frequency ranges of electromagnetic fields
