A scientific advisory board is scrutinizing a disputed government report that suggested possible cancer links to high-voltage electric power lines.

Authors of the draft report by the Environmental Protection Agency provided details of the findings to the 17-member panel for four hours Monday. One official said that while more conclusive studies are needed, "we're not way out in left field."The report, first made public last summer, concludes there is considerable evidence from more than a dozen scientific studies over the past decade that high exposure to electromagnetic fields from electric power lines are "a possible, but not proven, cause of cancer in humans."

Dr. Robert McGauhy, a participant in the EPA study, said that while the evidence does not conclusively prove a link between cancer and electromagnetic fields, it indicates the matter should not be dismissed without more detailed study.
