Abstract:
The ratio of
239Pu 129.3 keV and
241Am 59.5 keV γ peak areas was measured by well-type HPGe γ spectrometer for filter samples and reference solution, respectively. Atom ratios of
241Am and
239Pu in filter samples were calculated according to the count ratios and the atom ratio of
241Am and
239Pu in reference solution. Then filter samples were digested chemically and the contents of
241Am and
239Pu were determined using isotope dilution mass spectrometric (ID-ICP-MS) analysis combined with radiochemical separation. The results with two methods are coincident with each other within the uncertainties.
