RE-ACTIVATABLE RADIATION SOURCE FOR BRACHYTHERAPY

A method can comprise irradiating an active element having an initial total activity between zero and thirty curies of ytterbium-169 and a volume between about two cubic millimeters and about four cubic millimeters. Irradiation can be ceased before the active element surpasses a total activity of th...
