Americium-241 (Am-241)


Am-241 sources are both gamma rays and alpha particles emitters. They are applied in industrial gauging, including X-Ray fluorescence analysis systems, in the measurement of glass, plastics, rubber and light alloys (for example, thin-section aluminium) for which beta sources are not suitable. Isotope JSC supplies Am-241 sources of the Russian design manufactured by FSUE «PA «MAYAK». There is a wide variety of standard designs and activities.
