2021-04-23 · Radium-226 Decay Chain: Radium-226 (1600 year half life) yields an alpha particle and Radon-222; Radon-222 (3.82 day half life) yields an alpha particle and Polonium-218; Polonium-218 (3.05 minute half life) yields an alpha particle and Lead-214; Lead-214 (26.8 minute half life) yields a beta particle and Bismuth-214; Bismuth-214 (19.7 minute half life) yields a beta particle and Polonium-214; Polonium-214 (0.16 millisecond half life) yields an alpha particle and Lead-210; Lead
23. The disintegration of the radioisotope radium-226 produces an isotope of the element radon and alpha radiation. The atomic number of radium. (Ra) is 88
α-decay process The nuclide Ra(226,88) decays by alpha exission to Radon Rn(222,86). The speed of the emitted α particle is determined experimentally (the curvature if its path in a transverse magnetic field), or evaluated by determinig the related mass defect. It is about 1.52 x 10 7 m/s ( 5% c). 2018-03-29 · Explanation: And mass and charge are (almost conserved) in nucular reactions 226 88 Ra → 222 86 Rn + 4 2H e2+ + 2e− and congratulations, I think this is the first time for a long time that I have had to look up an elemental symbol on the Table.I thought for a moment that radon≡Rd.

Radium-226 is part of the uranium decay series decay chain The series of decays or transformations that radionuclides go through before reaching a stable form. For example, the decay chain that begins with Uranium-238 culminates in Lead-206, after forming intermediates such as Uranium-234, Thorium-230, Radium-226, and Radon-222.
