An increased risk for acute leukemia was observed for children with Down syndrome and a residential exposure to magnetic fields of 0.6 µT or more. The authors concluded that the association between magnetic fields and acute leukemia in children with Down syndrome suggested the possibility of a causal role for magnetic fields in the etiology of leukemia among a genetically susceptible subgroup of children.
Only spot measurements of magnetic fields were collected.
