This is a multicenter case-control
study designed to determine whether preconception gonadal doses
from ionizing radiation are higher in the parents of children with
leukemia than in parents of healthy children. The study sites are
Colorado, Atlanta, and San Francisco. Cases are children with
leukemia and controls are children selected at random from the same
population. The next older sibling will be used in a second control
group. The main exposure of interest, parents' gonadal doses from
ionizing radiation during the 6 months before conception, will be
quantified by taking detailed histories.
