Descrição: The decay statistics of {sup 90}Y have been studied from the count data collected during the radioactive {beta}{sup {minus}} decay from a carrier-free isotope of {sup 90}Sr-{sup 90}Y. The values of the relative Allan variance exceeded those predicted for a simple Poissonian process for counting times longer than 10 min and reached a limiting value called the flicker floor attributed to 1/{ital f} fluctuations. This study was extended for various energies of the {sup 90}Y spectrum.
