Analysis of ¹³⁷Cs radionuclides activities in Cs-zeolite using gamma spectrometry

¹³⁷Cs Radionuclide activity analysis has been carried out. The objective is to determine the activity of the ¹³⁷Cs radionuclide in Cs-zeolite are packaged in the form of point source. Analysis of ¹³⁷Cs Radionuclide activities in Cs zeolite samples was determined by measuring intensity of the isotope ¹³⁷Cs gamma energy at 661.7 keV use-y spectrometer. Before measurement the sample, was first carried out measurements of ¹³⁷Cs radionuclide in certified point standards from Amersham, to determine the efficiency value. Result the standard sample measurement obtained the efficiency value of 43.98%. Efficiency values obtained are used in the calculation of sample activity. On the measurement of the intensity of the sample obtained results dose rate 196.4537 cps with a standard deviation of 0.5274. By using standard measurement efficiency values obtained by the calculation of the average activity of the radionuclide ¹³⁷Cs in Cs-zeolite 524.9082 Bq. Deviation measurements were below 5% (0.27% ) so that the analysis of the activity of radionuclide ¹³⁷Cs in Cs-zeolite samples using gamma spectrometer can be accepted with a 95% confidence level.
