This Web application will allow you to calculate the activity of a radionuclide after a specified interval of time. The list of radionuclides excludes Figure 8-1: Decay scheme of 137Cs. t1/2 is the half-life of the nuclide under consideration. Table 8-2: Branching ratios for major 152Eu gamma rays.

152 63 1 decay scheme 2 nuclear data 2. 1 electron capture. True coincidence summing correction in gamma spectroscopy. The decay of mass-spectrometrically enriched 152 Eu has been studied using a Siegbahn-Slätis beta ray spectrometer, a scintillation spectrometer and a gamma- gamma coincidence device. From the analysis of the beta spectrum _{α K} of the 344 keV gamma radiation is found to be 0.033 ± 0.001. the accuracy ofthe decay scheme. Ag–g coincidence experiment is described in the current study with the aim ofchecking the level scheme ofthe daughters of13-year 152Eu decay and the placement ofthe observedg-ray transitions.
