Evidence‐based approaches

Rationale

Unsealed source therapy is complex because, in addition to the external hazard, there is an internal hazard from contamination arising from contact with the radiopharmaceutical itself or with the patient's body fluids.
Once a patient has been given a radioactive material, they become radioactive themselves, how much and for how long being dependent on the type and amount of radioactive material used.
The safety of all staff caring for these patients can be assured by implementing very detailed nuclear medicine and physics protocols and procedures.
