  • Systems and methods for assaying a liquid sample or alumina column for molybdenum content
    Patent number: 9709531
    Abstract: 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.
