Radio Frequency Non-Ionizing Radiation in a Community Exposed to Radio and Tv Broadcasting

Biomonitoring of Estrogen and Melatonin Metabolites Among Women Residing Near Radio and Television Broadcasting Transmitters

“…1,2,44 -50 RF exposures in this study were quantified using in-home power density measurements and other RF exposure parameters that were validated using a geographic information system (proximity, transmitter line of sight visibility, elevation). 23 Each RF exposure parameter was associated with an increase in E1G excretion among postmenopausal women, and the effects persisted with adjustment for potential confounding factors. Results from this investigation also indicated that personal exposure to temporally stable 60-Hz MFs increase E1G excretion among postmenopausal women.…”

“…A sample of 280 randomly selected male and female participants aged Ն8 years was recruited from 161 residences with high (Ͼ4.0 W/cm 2 ), medium (0.5 to 4.0 W/cm 2 ), or low (Ͻ0.5 W/cm 2 ) RF exposures. 23 The study participation rate was 64% among eligible persons contacted, and the mean age and mean residential power density did not differ between participants and nonparticipants. A total of 127 postmenarche women aged 12 to 81 years participated in the study, conducted between September 2002 and December 2003.…”

“…23 A population census identified 576 homes and 1375 individuals in the study area. A sample of 280 randomly selected male and female participants aged Ն8 years was recruited from 161 residences with high (Ͼ4.0 W/cm 2 ), medium (0.5 to 4.0 W/cm 2 ), or low (Ͻ0.5 W/cm 2 ) RF exposures.…”

“…The average distance from each residence to 15 major transmitters in the study area, the home elevation, and the percentage of transmitters visible from each home were used for RF exposure assessment along with the house average power density. 23 Personal exposure to 60-Hz MFs and ambient light was logged continuously at 15-second intervals using EMDEX II meters (Enertech, Campbell, CA) adapted with a light sensor (Grasby Optronics, Orlando, FL). 24 Each participant wore an EMDEX meter at the waist during the day, and placed it bedside on nonconductive material adjacent to the waist during sleep.…”
