gamma decay beta decay alpha decay
Alpha, beta, and gamma radiation were first observed from a sample of Radium in a magnetic field.
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
alpha decay, beta decay, and gamma radiation
radiation
nuclear decay, such as alpha decay or beta decay.
alpha decay, beta decay, and gamma radiation
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
The only possible product of the alpha decay of 92238U is 90234Th.
Radon-198 does not decay via beta decay. It is thought to decay by alpha decay, but that is not certain. The equation would be ... 86198Rn -> (Alpha, T1/2 = 86 ms) -> 84194Po + 24He2+
