While 153 Eu is observationally stable, 151 Eu was found in 2007 to be unstable and undergo alpha decay. The half-life is measured to be (4.62 ± 0.95 (stat.) ± 0.68 (syst.)) × 10 18 y which corresponds to 1 alpha decay per two minutes in every kilogram of natural europium.

152 Eu (half-life 13.516 years) and 154 Eu (half-life 8.593 years) cannot be beta decay products because 152 Sm and 154 Sm are non-radioactive, but 154 Eu is the only long-lived "shielded" nuclide, other than 134 Cs, to have a fission yield of more than 2.5 parts per million fissions.

A 24-level decay scheme was devised and the transition probabilities were analyzed in terms of adiabatic theory and in terms of the Recommended Nuclear Decay Data Cs-134.

lived isotopes, three (europium-152, europium-154, and europium-155) are produced by the fissioning of uranium and plutonium and are present at Department of Energy (DOE) environ-mental management sites such as Hanford. These three isotopes have half-lives ranging from 5 to 13 years, and they decay by emitting a beta particle. A

Similarly, the intensities of the 720 beta group and the 771 keV gamma line indicate the possibility of a weak 361 keV gamma ray between the 1116 keV and the 755 keV levels.
