A patient can be released after receiving a therapeutic radiopharmaceutical if the exposure dose likely to others does not exceed how many rems?

The correct value for the maximum exposure dose to others that allows for a patient's release after receiving a therapeutic radiopharmaceutical is 0.5 rem. This standard is established to ensure that the exposure to individuals who may come into close contact with the patient remains within acceptable safety limits.

The criteria for release are based on radiation safety guidelines that aim to minimize unnecessary exposure to others, especially in a public or home environment. The 0.5 rem threshold reflects a balance between therapeutic effectiveness for the patient and the safety of others. This guideline helps prevent potential health risks associated with radiation exposure while allowing patients who have undergone certain radiopharmaceutical treatments to return to their normal activities safely.

Understanding this threshold is vital for healthcare providers in making informed decisions about patient discharge and for ensuring compliance with safety regulations in nuclear medicine practices.
