The value in parentheses is the 1 sigma counting error expressed as percent in the concentration measurement (0%).
deviation (S.D.)} is shown for the collection efficiency.
(b)
Aliquot determined by radiochemical analysis.
Actual
(c)
Calculated collection efficiency of MICE samples using Equation 1.
(d)
Measured collection efficiency of MICE samples calculated from the first MnOg cartridge (A) and the plutonium concentration in the
filtrate determined by radiochemistry (RC).
