Description

Radium: A radioactive element of the alkaline earth series of metals. It has the atomic symbol Ra and atomic number 88. Radium is the product of the disintegration of URANIUM and is present in pitchblende and all ores containing uranium. It is used clinically as a source of beta and gamma-rays in radiotherapy, particularly BRACHYTHERAPY. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Toxicity

Radium-223 is safe and straightforward to administer using conventional nuclear medicine equipment. In post hoc analyses, radium-223 was safe regardless of concurrent abiraterone or enzalutamide. Median overall survival appeared longer when radium.-223 was used earlier in patients with less prior treatment.
