 A diagnostic reference level is a form of investigation level used as a tool to aid in optimisation of protection in the medical exposure of patients for diagnostic and interventional procedures. It is used in medical imaging with ionising radiation to indicate whether in routine conditions the amount of radiation used for a speciﬁed procedure is unusually high or low for that procedure. For nuclear medicine the administered activity (amount of radioactive material) or preferably the administered activity per unit of body weight is used. Also see ‘DRL quantity’.&lt;br /&gt;

Dose levels in medical radiodiagnostic practices or in the case of radiopharmaceuticals levels of activity for typical examinations for groups of standard- sized patients or standard phantoms for broadly deﬁned types of equipment. These levels are not expected to be exceeded for standard procedures when good and normal practice regarding diagnostic and technical performance is applied.&lt;br /&gt;
