Model		50 Hz ELF exposure to children in Japan and correlation with brain tumors
Details		Brain tumor cases in Japanese children (0-14 years old, n = 55) were analyzed for correlations with 50 Hz ELF exposure. Magnetic field exposures were recorded in the child's bedroom for 1 week as well as spot measurements in other rooms of the home. The authors report a correlation with increasing magnetic field strength measurements (OR = 0.74; 95% CI 0.17-3.18 for 0.1-0.2 microT, OR = 1.58; 95% CI 0.25-9.83 for 0.2-0.4 microT, OR = 16.8; 95% CI 1.85-153 for > 0.3 microT, OR = 10.9; 95% CI 1.05-113 for > 0.4 microT). The authors also report a significant dose response correlation with proximity to overhead power lines (OR = 1.88; 95% CI 0.28-12.8 within 50 meters, and OR = 1.60; 95% CI 0.37-6.83 from 50 to 100 meters. The authors emphasize that this association is not explainable due to confounding factors or selection bias.
