Study of the half-life of ¹²³I and the determination of possible radionuclidic impurities

During the process of production of the radiopharmaceutical nuclear reactor or cyclotron, impurities can be generated from biological, chemical and radionuclidic. The development of the present work was to study the half-life of Na¹²³I sample produced in IEN (Institute of Nuclear Engineering) using the technique of gamma-ray spectrometry with germanium detector in order to Identify such impurities. The results Indicate values of half-life consistent with recent publications with a deviation of 0,08% and 0:11% of uncertainty as well as the identification of impurities to radionuclides ^95mTc, ⁹⁶Tc and ¹²¹Te.
