The meters were worn on the hip in a belted pouch. During the sleep, subjects were instructed to leave the meter beside the bed, close to the body, but not near electrical and electronic devices.
59 workers, 26 men and 33 women, engaged in different occupations were included in the study: 26 in clothing production, 14 in local utility company, 6 primary school teachers, 5 in engineering industry and a further 8 in other occupations. Morning urine samples were collected twice: 1) on Friday after 4 days of occupational exposure or 2) on Monday after 2 days of no occupational exposure.
MF was measured in all subjects using a personal exposure meters EMDEX Lite. The meter measures magnetic field induction in space along three orthogonal directions and calculates the values as the quadratic sum of all three directions.
