RISK COEFFICIENTS
Both BEIR I and BEIR III risk coefficients
follows:
are used.
These are as
BEIR I
Cancer--Minimum:
~Absolute risk of leukemia (26 x 10-6 rem-l) +
30 year elevated risk for other cancers
(61 x 10-6 rem-l) = 87 x 10-6 rem-l.
Maximum:
Relative risk of leukemia (37 x 10-6 rem-l) +
lifetime elevated risk (421 x 10-6 rem-l) =
458 x 10-6 rem-l.
Genetic Effects:
0.2% per rem in first generation.
BEIR 111
Cancer--Minimum:
Absolute lifetime risk of cancer for continuous
exposure, 67 x 10-6 rad-l (low LET) based on
linear quadratic model.
Maximum:
Relative lifetime risk of cancer for continuous
exposure, 430 x 10-6 rad-l, based on linear
model .
Genetic Effects--Minimum:
ix
10-6 increase per rem in first
generation.
10-6 increase per rem in first
generation.
Maximum:
Z3X
