Changes

==For family members, caregivers and the public==

<br/>

When a patient is exposed to external sources of radiation during [[diagnostic radiology]] or [[Radiation therapy]], there is no residual radiation remained in the patient after the procedure, and the patient poses no radiation risk to family members or the others who provide care to the patient, and the general public the patient may come into contact. However, when [[nuclear medicine]] is used for [[diagnostic radiology]] or [[Radiation therapy]], protection of family members, other carers and the public, should be considered as the patient may remain “radioactive” for some time following the administration; the radiopharmaceuticals administered to the patient would need some time to physically decay or be biologically eliminated ([[ICRP Publication 94]] Release of Patients after Therapy with Unsealed Radionuclides; [[ICRP Publication 105]] Radiological Protection in Medicine).
