Radium (88 Ra) has no stable or nearly stable isotopes, and thus a standard atomic weight cannot be given. The longest lived, and most common, isotope of radium is 226 Ra with a half-life of 1600 years.

Part 2 – Radiation Characteristics Radium is a radioactive element for which no stable isotope is known. The mass numbers of the known radioisotopes range from 206 to 230. Among them, two radium radioisotopes, 226Ra and 228Ra, are very significant from a radiological protection point of view due to their It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Ra-226 (Radium, atomic number Z = 88, mass number A = 226).
