Abstract: The routine operation of a nuclear or radioactive installation generally involves the release of radioactive liquid and/or gaseous effluents. At the Nuclear and Energy Research Institute – IPEN there are several nuclear and radioactive facilities, developing activities in the field of nuclear energy. IPEN’s Radioprotection Management has established a radioactive effluent sampling program to determine the amount of radioactive material (source term) released into the environment and to detect immediately any unplanned release above the pre-established operating limits. The IPEN Environmental Radiological Monitoring Program – ERMP evaluates the levels of radioactivity to which individuals of the public are exposed through the analysis of atmospheric samples; the main objective of an ERMP is the confirmatory radiological control, which estimates whether the assumptions made in the calculation of the dose, from the source term, are correct. The objective of the present work is to present the gaseous radioactive effluents control and the radioactivity assessment in the atmospheric air at IPEN’s campus, since there were implanted in 1988 at the Laboratory of Environmental Radiometry of IPEN. In both, gaseous radioactive effluents control and radioactivity assessment in the atmospheric, cellulose and charcoal cartridge filters are analyzed by gamma spectrometry – HPGe weekly, from the IPEN’s radioactive facilities, Accelerators and Cyclotron Center, IEA-R1 Research Reactor Center, Radiopharmacy Center - Building I and II and each 15 days collected from three air samplers located near the nuclear and radiation facilities of IPEN, respectively. The radionuclides determined in the majority of the samples throughout the sampling period were 131I, 18F and 67Ga.

Abstract: Chemical composition of mineral water is the result of soil and water interaction and depends on the soil geology, because the chemical elements become part of these waters through the leaching and dissolution processes of soil. Mineral waters are defined as those that come from natural springs or that are artificially collected with chemical composition or physical chemical properties which imbues them with medicinal action that distinguishes them from ordinary water. According to the mineral summary of Departamento Nacional de Produção Mineral - DNPM, the consumption of mineral water has been increasing year by year, being in 2014 the global consumption 6.2% greater than in 2013 (which already had consumption 7.0% greater than in 2012), a fact that reinforces the importance of the characterization and regulation of the mineral waters. In thermal parks as Caxambu’s park, the waters are used as health therapy, diuretic waters, cathartic waters and anti-inflammatory waters. Parque das Águas of Caxambu, the largest mineral water park in the world, has 12 springs: Leopoldina, Beleza, Duque de Saxe, Princesa Isabel and Conde D’Eu, Dom Pedro, Viotti 1 and 2, Venâncio, Mayrink I, II and III and Ernestina Guedes and also a 60 m deep geyser. Thus, the main goal of this study was to perform a chemical characterization of these waters in which the elements Ba, Ca, Co, Cr, Cs, Eu, Fe, K, La, Na, Rb and Sb were found using Instrumental Neutron Activation Analysis – INAA technique. Mineral water samples were dried in a cellulose substrate and irradiated at the IEA-R1 reactor in which they were exposed for 6h to a thermal neutron flux of 1012 neutrons per cm2 per second. The results showed a similar behavior among the samples and it was possible to identify a higher concentration of Na, K and Fe and predominance of alkaline and alkaine earth metals in all samples. Further, Venâncio, Beleza, Ernestina springs and geyser showed the highest concentrations of these elements.

Abstract: Taiaçupeba reservoir, located in the state of São Paulo, Brazil, belongs to Producer System of Alto Tietê (Sistema Produtor Alto Tietê –SPAT) and it is responsible for water supply for about 3.1 million of people. The water quality of a reservoir became very important in the last decades due to the increase of environmental degradation of the soil and its several uses. Trace and major elements can accumulate in high levels in soil and sediment, and the study of its concentration can indicate if the ecosystem is polluted. Therefore, the study of soil profiles and sediment cores are an important tool for the understanding of geophysical and geochemical aspects of aquatic ecosystems. The objective of this work was to present the elements As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Ta, Tb, Th, U, Yb and Zn concentrations using Instrumental Neutron Activation Analysis (INAA) in four soil profiles and four sediment cores collected in the influence area of Taiaçupeba reservoir. To verify if these elements could be enriched and the ecosystem polluted the Enrichment Factor and the Geoacumulation Index were also used. Soil profiles were collected in trenches up to 2m deep and sampled every 5 cm; in the laboratory the samples were dried at room temperature. The sediment samples were collected with a manual PVC sampler sliced every 2 cm or according to their textural characteristics, and dried in an oven at 50 C; the length of the sediment cores ranged from 42 cm to 61 cm. After drying, soil and sediment samples were sieved in a 2 mm mesh and packed in polyethylene bottles for INAA. The elements Na, As and Sb presented the highest values for both soil and sediment samples, implying in continuous, regular and spatial monitoring of the reservoir. One sediment core presented a very high concentration of the element Zn when compared to the values of the Upper Continental Crust, indicating a possible anthropic contribution from the region’s industries and classifying the reservoir as extremely polluted in relation to this element. In the evaluation of the enrichment factor it was concluded that the soil presented very high enrichment for the elements Na, As and Sb and the sediment presented very severe enrichment for the elements Na, As and Zn.

Abstract: Mineral water, according to the Brazilian Law N 7.841 of August 8, 1945, "are those from natural springs or springs artificially captured that have chemical composition or physical or physicochemical properties other than ordinary waters, with characteristics that give them a drug action". In this same law, mineral waters can be classified according to their chemical composition in: oligomineral, radiferous, alkaline-bicarbonated, alkalineearthy, sulfated, sulphurous, nitrated, chlorinated, ferruginous, radioactive, thorioactive and carbogasous. In several Brazilian hydromineral resorts, springs of radioactive mineral water are commercially exploited and are consumed by the population that believes this practice is beneficial. For example, in thermal parks like Caxambu, Cambuquira, São Lourenço and Lambari (MG), the waters of the various springs are used for human consumption and are often associated with medicinal use, like diuretic and cathartic waters (with properties of cleaning, purification, facilitating hepato-biliary functions and stimulating intestinal function directly or indirectly), and waters with antiphlogistic properties (anti-inflammatory). Therefore, due to the recommendation of these waters as a form of treatment spent in spas, the present work was developed in Centro de Radiometria Ambiental – IPEN, with the aid of those responsible for the spas of Lambari and Águas de Contendas and, with the objective to perform an inorganic chemical characterization of the mineral waters of Parque das Águas of Lambari and Águas de Contendas. Samples of mineral waters were analyzed in duplicates and concentrated from 500 mL. The samples were irradiated at the IPEN Research Reactor IEA-R1, for a period of 6h under a thermal neutron flux of 1012 n cm􀀀2s􀀀1. In the samples of mineral waters of the Parque das Águas of Águas de Contendas the elements Ca, Co, Fe, Hf, K, Na, Rb, Sb, Sc, Th, Zn, La and Sm were found. Similarly, in the Parque das Águas of Lambari the elements Ca, Co, Fe, K, Na, Rb, Sb, Sc, Zn, La and Sm were found. The analysis of the samples of these water parks evidenced that the elements of greatest occurrence were La and Co.
