Study: Leukemia risk no
                     higher near power lines

                     -- Children exposed to
                     electromagnetic fields by living
                     near electrical power lines are not
                     more susceptible to developing
                     leukemia, a study released
                     Wednesday shows. 

                     Acute lymphoblastic leukemia is the most common childhood
                     cancer, affecting about 2,000 children each year and killing 30
                     percent of them. Doctors know it can be caused by exposure to
                     conventional radiation, but, otherwise, the cause of the disease is
                     unknown. 

                     The new findings from the
                     National Cancer Institute
                     are published in
                     Thursday's New England
                     Journal of Medicine.
                     Researchers hope they
                     calm fears that arose in
                     1979 when some scientists found a connection between cancer
                     and the fields given off by power lines and electrical appliances. 

                     More than a dozen studies have been done in the last 18 years in
                     an attempt to prove or disprove the suspected link. 

                     "Our study, overall, shows no evidence of an increased risk of
                     childhood acute lymphoblastic leukemia at residential
                     magnetic-field levels experienced by most children in this country,"
                     said Dr. Martha Linet, who led the study team. 

                                             The study, which was financed by
                                             the NCI and University of
                                             Minnesota's Children's Cancer
                                             Institute, looked at 638 children
                                             with leukemia and compared their
                                             living condition with those of 620
                                             youngsters without cancer. 

                                             Unlike past studies, the new
                     research directly measured electromagnetic fields in the home and
                     in past residences where a child had lived. Other studies simply
                     estimated a child's exposure. 

                     Researchers also checked to see if the mother had lived near
                     power lines when she was pregnant. 

                     In an editorial, Journal of Medicine Deputy Editor Edward
                     Campion said the new findings should put the controversy over
                     power lines and childhood leukemia to rest. 

                     "In recent years, several commissions and expert panels have
                     concluded that there is no convincing evidence that high-voltage
                     power lines are a health hazard or a cause of cancer," he said.
