ICRP reports 73 and 86

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
