Resumo IPEN-doc 31067 Caracterização química inorgânica de oleaginosas consumidas na cidade de São Paulo2024 - NASCIMENTO, BARBARA F.; DAMATTO, SANDRA R.Resumo IPEN-doc 31063 Validação, cálculo dos limites de detecção e quantificação do material de referência certificado SRM 2711a - NIST por INAA2024 - SILVA, THIAGO C.; DAMATTO, SANDRA R.Resumo IPEN-doc 30944 Radiation dose assessment from NORM residue used in the circular economy2024 - NISTI, MARCELO; SAUEIA, CATIA; DAMATTO, SANDRA; MADUAR, MARCELOBiota and human beings are exposed to naturally occurring radionuclides present in several natural resources [1]. Phosphogypsum (PG) is classified as a Naturally Occurring Radioactive Material (NORM) residue of the phosphate fertilizer industry. PG residue presents in its composition radionuclides of the natural U and Th decay series and stored in stacks by the phosphate industries, which can represent risks to environment and human from the radiological protection point of view, such as: atmospheric contamination, pollution of groundwater, trace elements and radionuclides, radon emanation, inhalation of dust and direct exposure to gamma radiation. Some possible applications of this residue are soil conditioners, resulting in an increase of agriculture productivity, or building materials [2]. The Brazilian regulatory body ruled that PG would only be permitted for use in agriculture if 226Ra and 228Ra activity concentrations do not exceed 1 Bq g-1, for each radionuclide [3]. On the other hand, the safe reuse of PG residue avoids depletion of non-renewable resources, decreases the stacks and consequent reduces the possible environmental impact. Also adds value to PG, considering the principles of sustainable development and the principle of the circular economy. This study's aims were to evaluate the estimated radiation doses in biotas and humans considering two scenarios: PG stack and application of PG in agriculture, using the ERICA Tool 2.0 [4] and NORMALYSA Tool 2.0 [5]. For the PG stack, estimated radiation doses (external and internal) to the worker and biota around the stack were evaluated. In the agriculture (soil amended with PG residue), the estimated radiation doses to the farmer (external and internal), consumers of agricultural products (internal) and biota (external and internal) were evaluated. In this paper, one application per year of PG residue in the soil and the maximum value of the Brazilian regulatory were considered.Artigo IPEN-doc 30680 Groundwater vulnerability and aquifer recharge modeling by the water table fluctuation method on a nuclear and radioactive facility2024 - STELLATO, T.B.; PIRANI, D.A.; LIMA, S.R.M.; VIANA, F. de S.; MONTEIRO, L.R.; DAMATTO, S.R.; COTRIM, M.E.B.Artigo IPEN-doc 30655 One year of Be-7 measurement in rainfall collected in different points in the city of São Paulo, Brazil2024 - DOMINGOS, R.M.; LEONARDO, L.; DAMATTO, S.R.; MIRANDA JUNIOR, P.; ISIKI, V.L.; NISTI, M.B.; ALENCAR, M.M.; TEIXEIRA, L.F.L.; MADUAR, M.F.; NETO, J.O.A.Artigo IPEN-doc 30626 Caracterização química inorgânica e radiológica de oleaginosas consumidas na cidade de São Paulo2024 - NASCIMENTO, B.F.; DAMATTO, S.R.; LEONARDO, L.; SILVA, T.C.Artigo IPEN-doc 30619 Avaliação da concentração de metais no solo da área de influência do Reservatório Biritiba Mirim, São Paulo2024 - SILVA, T.C.; DAMATTO, S.R.; GONCALVES, P.N.Artigo IPEN-doc 30587 Inorganic chemical characterization of the soil from the springs at RPPN Fazenda Renópolis2024 - RODRIGUES, C.E.C.; DAMATTO, S.R.; LEONARDO, L.Artigo IPEN-doc 30542 Natural radionuclides in surface soils from Biritiba-Mirim reservoir, state of São Paulo, Brazil2024 - GONCALVES, P.N.; DAMATTO, S.R.; LEONARDO, L.; COTRIM, M.E.B.; SILVA, T.C.Artigo IPEN-doc 30527 Potential applications of water stable isotopes in nuclear facility environmental monitoring programs2024 - MONTEIRO, L.R.; STELLATO, T.B.; PASSOS, R.G.; DALMAZIO, I.; GOMES, H.B.; ALMEIDA, L.S. de F.; ESQUIVEL-HERNANDEZ, G.; DAMATTO, S.R.; COTRIM, M.E.B.
