A tiny amount of radioactive substance is injected into the vein during a bone scan. According to StJohn.org, the small amount is not enough to warrant precautions against radioactive exposure. However, the injection can cause discomfort, and it may cause a rare allergic reaction.

Pregnant women are advised that bone scans may cause injury to the fetus. Additionally, for women who are breastfeeding, there is the risk of contaminating breast milk through the use of the tracer.
