When radiation therapy is administered via the bloodstream, it is called unsealed radiation therapy. This is because the radioactive material is not sealed, but instead is contained within the patient's body and is excreted over time. External radiation therapy involves the use of a machine to direct radiation beams at the affected area, while radium is a type of radioactive material that was historically used in sealed radiation therapy.
