Atomic Mass of Radium. Atomic mass of Radium is 226 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.

Radium-226 - SIS

It contains 2 protons and 2 neutrons, for a mass number of 4. During α-decay, an atomic nucleus emits an alpha particle. It transforms (or decays) into an atom with an atomic number 2 less and a mass number 4 less. Thus, radium-226 decays through α-particle emission to form radon-222 according to the equation: Ra-226 and its short-lived decay products are the most radiologically significant ra dionuclides associated with uranium ore because: • The external gamma hazard is primarily due to Pb-214 and Bi-214.
