text: In the intervening years since this initial work to characterize element 97, considerable information about the physicochemical properties of berkelium has been obtained in spite of the rather limited availability and the short half-life (330 days) of 249Bk, the only isotope available in bulk quantities.
text: Its half-life is only 330 days: after that time, half the berkelium produced would have decayed.
