Instructor's Guide
a.
Exposed individual
OPTIONAL: The current rate of
cancer deaths in the US from all
There is scientific evidence for
causes is ~20%. Many things can
health effects (primarily cancer)
cause cancer, including high
from radiation doses well above
exposures to radiation. A 25,000
the annual limit for occupational
millirem dose would result in an
exposure (greater than 10,000
increased risk of cancer from 20%
millirem). The risks associated
(background rate) to 21%.
with occupational doses are
very small and considered
acceptable when compared to
other occupational risks.
For very large doses received
over a short period of time,
prompt effects (i.e., effects that
appear shortly after the
exposure) may result. These
doses are received typically
under accident conditions such
as the firefighters responding to
the Chernobyl accident. These
effects may include reddening
of the skin, vomiting, hair loss,
or even death.
b.
Future children of the exposed
individual
Heritable effects (i.e., genetic
changes to the parents sperm
and/or eggs that results in an
observed effect in their
offspring) from ionizing radiation
have been found in plants and
animals, but have not been
observed in human populations.
