This case study carried out to improve the situation of large gap between scientific evidence and public perception on Extremely Low Frequency-Electric and Magnetic Fields (ELF-EMFs) problems in Korea. According to literature review on techniques and applications for EMF risk communication (RC) in Korea and other countries, the program which is appropriate for Korean society for RC was developed and the questionnaire to survey on perceptional level on ELF-EMFs based on this program was also developed. As some results of survey the perceptional levels on ELF-EMFs problems from some primary-school students and adults according to the educational tools (a presentation, a brochure, and a VOD) and protocols which were developed for RC, we identified in this study that the educational programs for RC have some effects to supply the right information and to improve the perceptional level on ELF-EMF problems to the general population such as the primary-school students and adults in Korea.

The objective of this study was to evaluate Extremely Low Frequency Magnetic Fields (ELF-MFs) exposure level of housewives and the relation of residential environments with ELF-MFs exposure level in home. ELF-MFs measurements were performed for 58 housewives include 31 working women. Twenty-four hours personal MF exposure levels of housewives were slightly higher than working women as an arithmetic mean. However the median of 24 hours personal exposure levels for working women were significantly higher than housewives (p<0.05). The median of personal exposure levels due to the activity at home, working women were higher than housewives significantly (p<0.05). As a results of correlation of residential environments, such as their living environments, total income, type of water supply pipes, and distance from power line with ELF-MFs exposure level in home was different from the type of residence (p<0.05). This study could be informed as guidance for ELF-MFs exposure analysis in residential environment.
