<dt>Description</dt>
<dd>Pioneer experimental indication of an extremely low alpha activity due to $^{151}$Eu isotope (equivalent to $\sim$10--70~disintegrations/h-kg of $^{\sf nat}$Eu) is discussed in the framework of a simple, one-parameter model to alpha transitions developed by us recently. The present evaluated alpha activity is found equivalent to $\sim$18~disintegrations/h-kg, in excellent agreement with the observed decay rate. Partial alpha decay half-life evaluations for $^{147-153}$Eu isotopes are also reported.</dd>
