Summary: Radiation 2
•
For
working populations
, ICRP risk estimates of excess cancer mortality:
8.2 × 10
-2
per sievert for high doses and high dose rates
4.1 × 10
-2
per sievert for low doses and low dose rates
•
For the
general population
, ICRP risk estimates are:
11.0 × 10
-2
per sievert for high doses and high dose rates
5.5 × 10
-2
per sievert for low doses and low dose rates
•
Workers in the
nuclear industry
are
not more likely
to develop cancer
than non-nuclear workers
•
Irradiation
in utero
by diagnostic X rays gives
RR = 1.4
for leukemia
and childhood cancers. This is high because malignancies in children
are rare, but absolute risk is about 6% per gray, similar to risk
in adult A-bomb survivors
