Gamma Ray Standards
Other Mixtures
Analytics Mixed Gamma Standard utilizes the basic eight radionuclides listed as Option 1 in the Mixed Gamma-Ray Standards Table. The approximate gamma-ray emission rate for a 3 microCi (111 kBq) source is given as an example. Option 2 adds 241Am to the mixture to extend the energy range down to 59.5 keV. Option 3 adds 85Sr to give a gamma-ray emission at 514 keV, which is useful in some applications. Option 4 adds both 241Am and 85Sr. To further extend the low-energy range to 46.5 keV, 210Pb can be added to the mixture. In order to measure coincidence-summing effects 65Zn (1115 keV) and 54Mn (835 keV) can be added. Option 5 replaces the 203Hg in the mixture with 51Cr, and adds 85Sr. Option 6, True Coincidence Correction (TCC) mixture, is used with special software to correct for coincidence summing effects. Custom mixtures for other applications such as NaI(TI) spectrometry can also be prepared. See tables listed for all options.
