Childhood leukaemia close to high-voltage power lines--the Geocap study, 2002-2007.

In that age group, living within 50 m of the closest VHV-HVOL was significantly associated with AL (OR=2.6 (1.0–7.0)), with a significant trend with the inverse of the distance ( P =0.03), whereas there was no association for the older group (OR=1.0 (0.3–3.3) living within 50 m of the closest VHV-HVOL).

The study by Draper et al (2005) based on residence at birth and covering more than three decades (1962–1995) revealed associations with longer distances from power lines than previously envisaged, far above the threshold usually recognised as generating ELF-MF greater than background exposures, and with a positive trend with decreasing distance.
