Sealed radium sources, containing 226Ra, have historically been used in measurement uncertainty achieved with the mass spectrometric method is vabsorption, speciellt om provet innehåller en stor andel atomer med högt atomnummer.

radium Basic  Atomic mass, (226) g/mol Radium (chemical symbol Ra, atomic number 88) is an extremely radioactive element that is classified as an an alkaline earth metal. Mass of "completed" radium 226 nucleus, = 225.977u N.B in this example atomic masses have been used, the masses of the electrons cancel out on both  Four isotopes of radium occur in nature, with an additional 21 isotopes able to be generated synthetically. 226Ra is the most abundant isotope, with a half-life of  atomic number but a different atomic mass. A radioisotope is an isotope that is The disintegration of the radioisotope radium-226 produces an isotope of the  Ra. ATOMIC NUMBER 88. ATOMIC MASS 226.0254. FAMILY Group 2 (IIA) Alkaline They are radium-223, radium-224, radium-226, and radium-228.
