- Determination of natural radionuclides in waste generated in the potable water treatment plants of the Zona da Mata of the state of Pernambuco- Brazil Adriana Muniz de Almeida Albuquerque F. C. S. S. França P. B. Silveira A. C. Almeida E. E. G. Farias C. A. Hazin E. V. Honorato Biología Waste water radionuclide The water intended for human consumption must have qualities that meet the criteria required by health agencies. To meet these requirements, waters from natural sources are generally subject to purification procedures, which aim to minimize the presence of components that may present a potential health risk. Studies show that the processes of purification of water for human consumption are quite effective in the removal of the radionuclides. The material precipitated during the purification process may accumulate the radionuclides present in the treated water and this material is indicated as TENORM by the United States Environmental Protection Agency. This residue may have significant levels of radioactivity and, when discarded in the environment, without any treatment, can generate a problem of environmental impact and a risk to the health of the population. Thus, the present study aimed to evaluate the residues generated in PWTPs from the state of Pernambuco, from the determination of 226Ra and 228Ra, included in the potability criteria, and of the gamma-emitting, in order to corroborate the studies of this TENORM . The results obtained are in accordance with the literature and the classification of the residues generated in the PWTPs as concentrators of the radioactive components contained in the water supplied to the system, indicating the need for studies on the impact of the release of this residue to the environment, which is the usual way of disposal of this residue in the study region, considering the established patterns of radiation protection and the possible associated ecological risks. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280838028 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.2A Vol.7
