Abstract
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 .sup.99M, and further provided an electro-mechanical carrousel-type means for systematically positioning multiple source containers as desired by the user thereof.
Claims16
An apparatus for directly determining the contration of radioactivity of a source in a radiation-shielded closed container and for determining the volume of material to be withdrawn from the container such that the withdrawn volume will constitute a predetermined dose of radioactivity, the determination and withdrawal of the desired amount of radioactive material being accomplished without removing the container from its radiation shield, said apparatus comprising in combination:
- (a) a radioactive source container having a body in which the main volume of radioactive material is contained, said container being adapted for isolating an aliquot of predetermined volume of the radioactive material from the main volume;
- (b) radiation-shielding means within which said container is enclosed, said radiation- shielding means being adapted for isolating the radiation of said aliquot from that the main volume of radioactive material within said container;
- (c) radiation-detection means in operable association with said radiation-shielding means for sensing and converting the radiation from said aliquot into an electrical signal indicative of the concentration of radioactivity in the container.
