Module 2 Biological Effects
3. Biological effects of radiation exposure
Somatic effects refer to the effects radiation has on the
individual receiving the dose.
EO7 Define the term
Genetic effects refer to mutations due to radiation
damage to the DNA of a cell. When this change is in the
DNA of parental reproductive cells, it is called a
a. Somatic Effects
Somatic effects can best be described in terms of prompt
and delayed effects as discussed below.
3) Prompt Effects
Although rare in the nuclear industry, large doses are
typically acute radiation doses representing serious
overexposures. The biological effects of large acute
doses are as follows:
Prompt Biological Effects
None detectable through
symptoms or routine blood
Changes in blood.
