Americium solution with an isotopic composition of 88 % 243Am and 12 % 241Am was used as the source for the preparation of the spike material. The certified values of 5.696 (11)·10-9 mol g-1 and 0.136138 (54) were assigned for the amount content of 243Am and the n(241Am)/n(243Am) amount ratio, respectively.

Within Europe 241Am is considered a promising alternative heat source for radioisotope thermoelectric generators (RTGs) and radioisotope heating units Within Europe 241Am is a feasible alternative to 238Pu that can provide a heat source for radioisotope thermoelectric generators (RTGs) and radioisotope Americium-241 (241Am, Am-241) is an isotope of americium. Like all isotopes of americium, it is radioactive, with a half-life of 432.2 years. Am is the most Americium-241, AM-241, 241Am, radioactive solution, radionuclide.
