Bone scan radiation has an extremely limited effect, if any, on those around it, at least within safe limits. Bone scan patients need to inject drugs containing radioactivity. Since it takes some time for the drugs to metabolize, a certain amount of radioactivity theoretically still exists for a few days after the patient has had the test, before the drugs are completely metabolized. However, the dosage of the drugs used in the bone scan is safe for the patients themselves, so even if there is radiation to the people around them, the effect is minimal. There is no need to avoid people around you for a few days after the bone scanning test. At most, you should pay attention to pregnant women and women preparing for pregnancy around you and remind each other to keep a proper distance.
