In addition to β − decay (27.9 %), Eu-152 also decays with electron capture (72.1 %) and β + decay (0.03 %). The other three radionuclides decay only through β − decay (100 %). 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. with europium-152 and europium-154. If it is assumed that 100,000 people were continuously exposed to a thick layer of soil with an initial average concentration of 1 picocurie (pCi)/g, then the number of fatal cancers estimated for these 100,000 people is 7 for exposure to europium-152 and 5 for exposure to europium-154.
