한국인의 직업별 24시간 ELF 노출자계 현황 = Occupational Exposures to ELF Magnetic Fields over a 24-Hour Period Among a Sample of Urban Populations in Korea

다국어 초록 (Multilingual Abstract)

The objective of this survey is to characterize the extremely low frequency (ELF) personal magnetic field (MF) exposure of the general population in Korea. This is the first-ever personal MF exposure survey done in Korea. The participants of the survey on magnetic field exposure were randomly selected by occupation. The survey was conducted as follows: Study participants wore a magnetic field meter for about 25~28 hr, and the exposure data were stored in the meter every 4 s. The personal magnetic field exposure meter that was used for this survey was EMDEX-LITE, made by Enertech Consultants, Inc., USA. The participants were asked to record their activities so that magnetic field exposure can be evaluated for a 24-hr period. The personal MF exposure survey has been conducted for about four years, and the total number of participants was 466. To get the 24-hr exposure data is one of the main purposes of this survey. The survey also provided an opportunity to analyze exposures corresponding to different types of occupations. Therefore, the database was utilized to analyze the present status of occupational personal magnetic field exposure of Korean.
