The variation of the electron capture (EC) decay life-time of 89Zr as a function of environment has been measured with respect to the antiferroelectric-paraelectric transition in PbZr03 and the results (Ah/h = 0.1%) have been % compared to similar observations in BaTKB3 Zr)OJ. In ZrOz, the decay rate of a9Zr is insensitive to the crystallographic change from the cubic to the monoclinic form. The 89Zr EC decay rate shows a strong temperature dependence in the monoclinic phase.
