Naturally occurring europium (63 Eu) is composed of 2 isotopes, 151 Eu and 153 Eu, with 153 Eu being the most abundant (52.2% natural abundance).While 153 Eu is observationally stable, 151 Eu was found in 2007 to be unstable and undergo alpha decay.

Assuming the 238U decay chain 238U → 234Th → 234mPa has reached secular equilibrium For each pixel, the number of photons generated during read-out is proportional to the number of Eu ions that were 767:146–152. Noyes KL, SJ

In general, the higher a radionuclide’s specific activity, the shorter its half-life (decay rate), and the more “radioactive” it is when compared to one with a lower specific activity. The following is a listing of selected (greater than 100 million electron volt or “MeV”) radionuclides, ordered by element, that emit gamma ray photons during radioactive decay. Each entry gives the radionuclide symbol (i.e., I-131), followed by the photon energy (in units of MeV), followed by the photon yield (i.e., probability per decay). An activity of158Eu was produced by an (n, p) reaction in an enriched gadolinium target by means of 14 MeV neutrons obtained from a SAMES generator. The gamma radiation accompanying the beta decay of158Eu into158Gd was detected by means of a Ge(Li) spectrometer.

The α decay of europium isotopes has been recently investigated using a 370 g CaF 2:Eu low background scintillator [14], which contained Eu only as a dopant with mass fraction of just 0.5%. The authors of that paper mention the first indication of the αdecay of 151Eu nuclide to the ground state of 147Pm with a half-life of T 1/2 = 5 +11 −3

Correlated background from external bremsstrahlung generated in the electron detector is estimated to contribute less than 3 % of the observed radiative decay event rate. The intensities of weak gamma‐ray transitions in the 152 Sm level scheme from 152 Eu decay measured in two gamma‐ray coincidence experiments are compared; almost 40 new transitions with intensities around 10 −5 gamma‐rays per decay and 6 new levels were observed.
