Medical radiation sources are used deliberately in the healthcare of patients and are designed for use in a controlled manner. There obviously are some adverse health risks associated with the use of radiation in medicine <ref name="Pub105"/>, with higher amounts of radiation being associated with higher risks.

Experience has provided ample evidence that reasonable selection of the conditions under which ionising radiation is being used in medicine can lead to health benefits substantially outweighing the estimated possible deleterious effects.
