radiocolloid
A radiocolloid is a tiny particle that contains a radioactive element. It is designed to be injected into the body for medical purposes, such as imaging or treatment. Because of its small size, it can travel to specific areas, like lymph nodes or tumors, allowing doctors to see the area on scans or deliver targeted therapy. The radioactivity helps visualize or destroy abnormal cells, while the particles themselves are usually harmless if used correctly. Radiocolloids are a useful tool in nuclear medicine for diagnosing and managing various health conditions.
