dc.description.abstract	The decay rate of 7Be depends on the electron density at the nucleus and therefore may vary with the chemical environments of the Be atom. Using a 100% efficiency high-purity germanium detector, the decay constants of 7Be in Be2+(OH2)4, Be(OH)2 and BeO have been measured at unprecedented high precision (of +/-0.01%), resulting in T1/2 = 53.69 d, 53.42 d, and 54.23 d, respectively. The observed difference, by as much as 1.5%, clearly indicates that decay rates of nuclides undergoing electron capture decay are not necessarily constant as has always been assumed in geological, oceanographic, and environmental studies.
