Two objectives
Radiotherapy: deliberately uses radiation on patients to produce
deterministic effects
(tumor cell kill) - in this context some
deterministic effects and stochastic effects are accepted (=
side effects
)
Radiation protection: to manage and control exposures to ionizing radiation
to: 1) prevent and minimize the risk of
deterministic effects
which are
NOT intended: accidental medical exposure and ‘unacceptable’ radiation
effects to the patient (=
complications
) due to mistakes or suboptimal
irradiation practice; 2) minimize the risk of
detrimental effect
to
others; 3) reduce the probability of
stochastic effects
to the extent
reasonably achievable
