The decay chain of Radium 226 ends in stable lead (Pb-206). Approximately 49 gamma rays with energies ranging from 0.184 to 2.45 MeV are released during the decay from Radium to Lead. Because Radium-226 has a significantly longer half life than it’s daughter products, it will exist in secular equilibrium with it’s DECAY PATHWAY: Radium-226, half-life 1600 years, decays via alpha emission, 4870 keV (94.45% 4784 keV; 5.55% 4601 keV), to radon-222, 3.8235 days; decays via alpha emission, 99.92% 5489.5 keV, to polonium-218, half-life 3.10 minutes; decays via alpha emission, 99.998% 6002 keV, to lead-214, half-life 26.8 minutes; decays via beta (-) emission (48.9%, 670 keV maximum, 207 keV average energy; 42.2% 727.8 keV maximum, 227 keV average energy) and gamma emission (abs intensities: 37.6% 351.9 keV (a) Write the complete $\alpha$ decay equation for $^{226}\textrm{Ra}$ .

Click here👆to get an answer to your question ️ Write the nuclear reaction equation for alpha decay of the 226 88 Ra . Radium-226 has a half-life of 1622 years. It and its short-lived decay products emit alpha particles, beta particles, and gamma rays. One of the decay products, radon-222, is a radioactive gas. In clinical use, radium is contained in a metal container that stops alpha and beta particles and traps radon.

There are dozens of different gamma rays of varying energies and yields produced by the decay of 226 Ra and its progeny; energies range from less than 50 keV to about 2.5 MeV. When a nucleus of Ra (radium) decays, it emits an alpha particle and becomes an Rn (radon) nucleus. In general, during alpha decay, the atomic number (Z) is reduced by two, and the mass number (A), by four. For example, alpha decay generates Rn-222 with atomic number 86 and the mass number 222 from Ra-226 with the atomic number 88 and the mass number 226. An example of alpha decay is the historically important transformation of radium 226 into radon 222 through the emission of an alpha particle. This reaction releases 4.6 MeV, and leaves behind a radioactive noble gas (radon), which is what allowed Rutherford to observe the process in Montreal in 1898.
