WebA.1 What is radium-226 (Ra-226)? Ra-226 is a radioactive substance found in nature. Pierre and Marie Curie discovered radium in 1898 while conducting research with uranium ore. Ra-226 is produced by the radioactive decay of uranium-238. Radioactive decay occurs because certain atoms are WebNumber of neutrons in radium. We know that the atomic number of radium is 88 and the atomic average mass number is about 226. Neutron = 226 – 88 = 138. Therefore, a …
