RISK COEFFICIENTS
Both BEIR I and BEIR III risk coefficients are used.
follows:
These are as
BEIR I
Cancer--Minimum:
Absolute risk of leukemia (26 x 107 rem!) +
30 year elevated risk for other cancers
(61 x 107& vem!) = 87 x 1076 rem™!.
Maximum:
Genetic Effects:
Relative risk of leukemia (37 x 107& rem-!) +
lifetime elevated risk (421 x 107© rem-!) =
458 x 10-© rem7!,
0.2% per rem in first generation.
BEIR Til
Cancer--Minimum:
Absolute lifetime risk of cancer for continuous
exposure, 67 x 107® rad7! (low LET) based on
linear quadratic model.
Maximum:
Relative lifetime risk of cancer for continuous
exposure, 430 x 107® rad-1, based on linear
model.
Genetic Effects--Minimum:
Maximum:
75 x 107~© increase per rem in first
generation.
5.0 x 107°© increase per rem in first
generation.
