Resumen:
In this present thesis I have developed different analytical methods for the determination of the individual radionuclides in environmental samples. These samples studied are rich in natural radionuclides and mainly descendants of the decay chain of 238U, because these samples are byproducts or are under the influence of the industry NORM. This type of industry works on the basis of raw materials rich in natural radionuclides, generating waste with concentrations of radionuclides that can increase considerably the natural radiation activities on the environment that can be harmful to living beings that inhabit it. Moreover in these methods developed in this thesis was included a pre-treatment prior to the measurement of the sample in order to achieve the individual radionuclides free of interference elements. We find the development of different classical and manual and automated techniques in all experimentation articles. These methods included a combination of preconcentration techniques and selective extraction resin of radionuclides of interest that will be measured in different radioactive emissions measure equipments.
