Radiography and nuclear medicine provide doctors with essential information needed to prescribe the appropriate treatment. But the risks of radiation must not be neglected.
Radiation workers must comply with three radiation protection rules: time, distance and screening. For patients, such examinations must only be prescribed when the doctor needs to confirm a diagnosis. And in all cases, patients must receive the lowest possible exposure, without impairing the quality of the images.
In the field of radiotherapy, radiation protection is vital since patient exposure is the result of a compromise between the minimum level of exposure required to destroy the tumor and the exposure limit above which healthy tissue will be damaged.
