What is the beta decay of radium?
What is the beta decay of radium?
That isotope of Radium subsequently decays into Actinium-228 via beta decay, and so on until Lead-208 is the final end product. Since Lead-208 doesn’t decay, it is called stable, not radioactive.
What does RA 228 decay into?
beta particle
Radium-228 has a half-life of (5.75 years) and decays by emitting a beta particle.
What is the beta decay of carbon?
C decays by a process called beta decay. During this process, an atom of 14C decays into an atom of 14N, during which one of the neutrons in the carbon atom becomes a proton. This increases the number of protons in the atom by one, creating a nitrogen atom rather than a carbon atom.
What is the beta decay of radium 226?
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; …
What is the difference between RA 226 and RA 228?
The two most common isotopes of radium are radium- 226 and radium-228. Radium-226 has a long half-life (1,600 years) compared to that of radium-228 (5.75 years). Radium-226 decays by emitting the nucleus of a helium atom (alpha particle), whereas radium-228 emits an electron (beta particle).

What is product when U 234 undergoes alpha decay?
thorium-230
Uranium-234 nuclei decay by alpha emission to thorium-230, except for the tiny fraction (parts per billion) of nuclei which undergo spontaneous fission.
When the nuclide polonium 214 decays to lead 210 what kind of decay does polonium 214 undergo?
This corresponds to a alpha particle (42α). Polonium-214 undergoes d. alpha decay.
What type of decay does radium 223 undergo?
Radium-223 is an alpha particle-emitter with a half-life of 11.4 days. The specific activity of radium-223 is 1.9 MBq/ng. The six-stage-decay of radium-223 to lead-207 occurs via short-lived daughters, and is accompanied by a number of alpha, beta and gamma emissions with different energies and emission probabilities.
