Ra-226 was used in numerous medical applications during the 20 th Century as well. It was used in sealed and unsealed sources for cancer therapy applications. Ra-226 was fashioned into various sizes and types of sealed sources, many of which were called âneedlesâ because of their shape. Radium needles and other forms were implanted into cancerous tumors to arrest the cancerous growth. In unsealed form, Ra-226 has been used as a source of radon-222 for inhalation therapy.
