Gamma Spectrometry results for the 134Cs nuclear parameters

Abstract

¹³⁴Cs are produced directly as a fission product (low yield) and too obtained by neutron capture from ¹³³Cs non-radioactive. The National Laboratory for Ionizing Radiation Metrology (LNMRI/IRD/CNEN) of Rio de Janeiro performed standardization of this radionuclide. A solution of ¹³⁴Cs radionuclide was purchased from a commercial supplier for nuclear parameters determination such as activity and emission probabilities of some of its energies. ¹³⁴Cs is a beta gamma emitter with 754 days of half-life. This radionuclide is used as a standard in environmental, water, and food control. It is also important to germanium detector calibration The gamma emission probabilities were determined mainly for some energies of the ¹³⁴Cs by the efficiency curve method and the most uncertainties obtained were around 1.5 %.
