An electronic device for rapidly determining the concentration (i.e. mCi/cc) of radioactivity in a closed container, and for determining the volume of material needed to be removed such that the removed volume will constitute a predetermined amount of radioactivity, is disclosed; the device further incorporating novel features so that said determinations, and actual withdrawal of the desired amount radioactivity material may be accomplished without removing the closed container from its leaded radiation shield. This device also has provision for determining the percentage relationship of Molybdenum impurities in Technetium 99M, and further provided an electro-mechanical carrousel-type means for systematically positioning multiple source containers as desired by the user thereof.
