dc.description.abstractGamma spectrometry is an analytical technique extensively employed in radionuclide determination. The usual ease of sampling preparation, the wide range of natural and artificial radionuclides that can be determined, and the applicability of this technique in a variety of sample matrices are some of its advantages. However, some care is needed when the technique is intended to be used as a tool for identification and quantification of radionuclides comprised in radioactive decay series. In such situations, as the radioactivity contents in the sample can naturally vary along the time, the results are critically dependent of the radioactive equilibrium conditions of the sample. In this work, we outline some criteria to decide about the radionuclide equilibrium situation expected to occur in various kinds of samples and thus decide the procedure to be taken to assure the reliability of the results in such complex situations. Provided that such analysis is carried out, gamma spectrometry can be used even in the determination of radionuclides that do not directly emit gamma radiation, based on the concentration of their gamma-emitter decay products. Different procedures, especially related to the delay time and sample sealing to assure proper radioactive equilibrium conditions, are required prior to the sample measurement, according to the origin and composition of the analyzed materials.
