Abstract

In this paper, exposure levels of electromagnetic field were measured in residential environments andfrom appliances. First, the measurements of residential environments were taken in central locations inbedroom, living room, and kitchen in each home. Both arithmetic and geometric mean of normal-powercondition are higher than low-power condition (all electrical devices turned off/unplugged), and thebackground fields in homes show a geometric mean of about 0.022 uT. Second, we measured broadbandmagnetic fields of domestic appliances at various distances. The highest magnetic field is 44.3 uT from themicrowave oven, and the lowest is 1.4 uT from the Kimchi Refrigerator. The magnitude of magnetic fieldsfrom appliances dropped off at a rate inversely proportional to distance, but the ratio of drop-off on Koreanappliances is lower than US and UK
