The life-table methods used by Sielken and Valdez-Flores
in the calculations of the ECs, and LECs are based on the
BEIR IV methodology The calculations include recent US survival
rates [1] and recent leukemia mortality rates (2005 mortality
from CDC WONDER – http://wonder.cdc.gov/cancermort-v2005.

for the general population were calculated using the methodology
and default age-dependent adjustment factors (ADAFs) described
in USEPA [30,31] (see also [20,21]).
