Abstract
Development of technology has been caused that people expose to high level of electromagnetic fields (EMFs). The most important EMFs sources for public population are high pressure power line, radio, television, mobile phone, computer, tablet, and so on. Emitted electric and magnetic field can produce some human health impacts such as leukemia, cancer, brain disorders, and fertility problems. Therefore, EMFs have been became the subject of a large number of studies. The aim of this study is to investigate electric and magnetic field emitted by television (TV) sets, computer monitors and mobile phones in different distances and different conditions. Electric and magnetic field were measured by EMFs survey meter model HI 3603. The measured values were compared with ICNIRP public exposure limit and exposure levels were classified based on average intensity of the field (IF) method. The data analysis was conducted by SPSS 19 software. The electric and magnetic field emitted from mobile phones, TV sets, and LCD monitors in all distances and situation are lower than exposure limit. The exposure level class for TV set and mobile phone in different condition is low and for monitor in some vertical and horizontal distances is medium. There is need to public conduct essential protection against emitted EMFs by these devices. Also, electrical devices manufacturer should improve their production to reduce EMFs that emit from these systems.
