摘要： A system for assaying a sample for Molybdenum-99 content includes an inner ionization chamber including a well configured to receive the sample, an outer ionization chamber concentric with the inner ionization chamber, attenuating material positioned in the well, and a computing device. The computing device is configured to determine a first Molybdenum-99 content value of the sample based on a first current measured in the inner ionization chamber, determine a second Molybdenum-99 content value of the sample based on a second current measured in the outer ionization chamber, and determine a final Molybdenum-99 content value based on the first and second Molybdenum-99 content values.

摘要： A horizontal mixer (50) is disclosed. Multiple blades (92) are affixed to and rotate with a tumbler (80) of the mixer (50). These blades (92) extend within an interior mixing chamber (90) and are center-angled so as to promote a desirable mixing action within this chamber (90) (e.g. so as to fold a slurry within the chamber (90) onto itself). One characterization is that the blades (92) are oriented so as to direct a flow toward a common outlet region (78) within the tumbler (80) throughout at least a certain rotational angle. The mixer (50) is particularly suited for realizing a desirable homogeneity of particles within a slurry from which radioisotopes may be produced.

摘要： A slurry dispensing system (10) is disclosed. A peristaltic pump (28) may direct a flow of slurry out of a horizontal mixer (20) to a slurry dispenser (140). This slurry dispenser (140) may be operated on a programmed manner by a controller (260) to dispense slurry into a container (36). Both a bypass valve (172) and a dispensing valve (204) of the slurry dispenser may be opened/closed on a programmed basis by the controller (260) to deliver slurry to a container (36), such as a glass column. Slurry may be intermittently directed into a metering chamber (194) of the slurry dispenser (140), while the remainder of the slurry being directed into the slurry dispenser (140) may be recirculated back to the horizontal mixer (20).

摘要： A system for manufacturing radionuclide generators includes an enclosure defining a radioactive environment. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. The system also includes a conveyance system having a forward track and first carriages positioned on and movable along the forward track for conveying racks in a first direction. The conveyance system also includes a first walking beam mechanism magnetically coupled to the first carriages to move the first carriages. The conveyance system further includes a return track and second carriages positioned on and movable along the return track for conveying racks in a second direction opposite the first direction. The forward track and the return track form a loop.

摘要： A process for extracting Cs-137 from i) an acidic solution obtained by dissolving an irradiated solid target comprising uranium, ii) an acidic solution comprising uranium which has previously been irradiated in a nuclear reactor, or iii) an acidic solution comprising uranium which has been used as reactor fuel in a homogeneous reactor, the acidic solution i), ii) or iii) having been treated to harvest Mo-99, wherein the process comprises contacting the treated acidic solution with an adsorbent comprising ammonium molybdophosphate (AMP). In an embodiment, the AMP is combined with an organic or inorganic polymeric support, for example AMP synthesized within hollow aluminosilicate microspheres (AMP-C).
