Claim Text:
1. An assaying system, comprising: a housing; a well within said housing; a first ionization chamber within said housing and comprising a first gas; a second ionization chamber within said housing and comprising a second gas; an attenuating material positioned between said first and second ionization chambers, wherein said first ionization chamber, said attenuating material, and said second ionization chamber are positioned relative to one another such that when an eluate is positioned within said well and emits first and second radiation: 1) the first radiation reaches said first ionization chamber but is blocked from reaching said second ionization chamber by said attenuating material; and 2) the second radiation passes through said attenuating material and reaches said second ionization chamber; and a computing device configured to: 1) determine a first radioisotope content based on a first current associated with said first ionization chamber; and 2) determine a second radioisotope content based at least on a second current associated with said second ionization chamber.
