Full textWe have investigated the Gard and the eastern Paris basin environmental reconstruction by using U-series dating of speleothems. The first aim of this study was to validate the high resolution U-series dating of small size samples over the recent period (0- 10 kyr) for which this method is of difficult use. For this period, we also have tested the 226 Ra dating techniques for the U/Th dated speleothem. For the whole period on which U/Th is valid, several correction methods were compared in order to take into account bias due to detrital material within these impure carbonates. These methodological investigations enabled to investigate several research axes. We discussed the origin of speleothems breaking from a Gard cave. Speleothem U/Th dating has been used for a chronological scale for the Eastern Paris basin karstification. We have shown the importance of the presence and the erosion of a non carbonated cover overlying the karstified limestone on the speleothem uranium composition. .

Estudos radiométricos e radioecológicos vêm sendo desenvolvidos mundialmente, em busca do mapeamento de áreas com elevados níveis de radioatividade, um pré-requisito essencial na investigação da exposição à radioatividade ambiental. Nesse trabalho foram estudadas amostras de rochas e solo derivado de uma área efetivamente anômala em urânio no município de Pedra, Pernambuco, utilizando análises não destrutivas, com aplicação da espectrometria gama de alta resolução com detector HPGe, para os radionuclídeos das séries do 238U e do 232Th, assim como o 40K, calculando-se suas atividades específicas. Os valores de 238U variaram de menor que 2,8 a 79.092 Bq.kg-1; os de 226Ra de menor que 0,6 a 144.438 Bq.kg-1; os de 232Th de 6,9 a 1.903 Bq.kg-1 e os de 40K de menores que 4,7 a 2.274 Bq.kg-1. Uma estimativa dos teores, das taxas de doses gamas naturais e do rádio equivalente foram realizadas com base nos valores das atividades específicas. Os teores médios em solo foram 3,3 mg.kg-1 de 238U; 0,7 ng.kg-1 de 226Ra; 39,3 mg.kg-1 de 232Th e 3,4 mg.kg-1 de 40K; em rochas graníticas, os valores médios foram 2,0 mg.kg-1 de 238U; 0,6 ng.kg-1 de 226Ra; 40,2 mg.kg-1 de 232Th e de 3,1 mg.kg-1 de 40K; enquanto nas rochas cálcio-silicáticas anfibolíticas, as médias para 238U, 226Ra e 232Th foram 3.132 mg.kg-1; 1.886 ng.kg-1 e 119 mg.kg-1, respectivamente. A taxa de dose equivalente efetiva devida a radiação gama natural a 1 m da superfície e o rádio equivalente estimados, apresentaram, respectivamente, valores médios de 204 μSv.a-1 e 393 Bq.kg-1 para solo; 195 μSv.a-1 e 328 Bq.kg-1 para as rochas graníticas e de 20.993 μSv.a-1 e 70.124 Bq.kg-1 para as rochas cálcio-silicáticas anfibolíticas. Além disso, foi estimada a disponibilidade do urânio natural no solo da área com base na razão Th/U. No solo, o urânio apresentou baixa mobilidade (Th/U igual a 4,6) para pelo menos 80% dos pontos amostrados. Os resultados permitiram monitorar a exposição gama externa à qual os indivíduos que residem próximos a essas áreas estão expostos. Estima-se uma taxa de dose máxima superior a 43 vezes o limite recomendado para indivíduos do público, que é de 1 mSv.a-1. Recomenda-se que essas áreas sejam pouco utilizadas ou evitadas, de forma minimizar exposições desnecessárias

Full text131I is an iodine radioisotope widely used in nuclear medicine that can be used either for diagnostic or for treatment due to its physical decay by - and its high emission of -rays. It is produced at IPEN using the indirect reaction: 130Te(n,)131mTe 131Te 131I where TeO2 targets are irradiated in a Nuclear Reactor. There is also the possibility of producing 131I by the fission of 235U, where about 300 different elements are produced together with 131I. The 131I produced through this method presents high specific activity and radioactive concentration suitable for the labeling of molecules. The aim of this work was to develop a recovery method of 131I with the required quality to be used in Nuclear Medicine in the 99Mo production process through the route of acid dissolution of metallic 235U targets. 131I can appear in two phases of the process, both in the gaseous phase produced during the dissolution of metallic U targets and in the dissolution solution. This work studied the recovery of 131I in these two phases. Several materials were used for the capture and recovery of 131I at the two phases of the process, the gaseous one and the solution of dissolution of U targets. Columns of alumina with Cu, acid alumina with Cu, Ag microspheres, Cu microspheres, Ag nanospheres, anionic cartridges, Ag cartridges, anion exchange resin and activated charcoal columns were tested. Solutions containing 131I in 0.1 mol.L-1 NaOH were percolated through the materials and the eluted solutions were analyzed in a dose calibrator. The precipitation of AgI was also studied wth further dissolution of this precipitate with 0.1 mol L-1 NH4OH and 5% Na2S2O3. The recovery results varied according to the material, activated charcoal showed recovery yields between 42% and 83% but the recovery yield of the alumina column with Cu ranged from 20% to 85%. Tests with Ag nanospheres showed recovery yield of 26% using 0.1 mol L-1NaOH and 72% for Na2S2O3. Tests with anionic cartridges showed the best results with a recovery percentage ranging between 81 to 90%. Tests using 131I in the gaseous phase presented retention of 66.45% and its elution was not studied. The experiments with the AgI precipitation showed total retention of 131I. It can be concluded that the anionic cartridges and the precipitation of AgI have higher affinity for the retention of 131I, and alumina columns with Cu have great potential for its elution in a suitable chemical form.

Full textResearch on the distribution of natural radionuclides in Antartica is rare and thus, there is great interest in to know their occurrence and factors related to its mobilization, transference and accumulation in this extremely fragile environment. Natural radionuclides have been used intensively as tracers in the ocean, helping to better understand processes as sinking and particle ressuspention, water masses mixture and oceanic circulation. 234Th (t½ = 24.1 days) is a particle-reactive radionuclide produced continuously in seawater by the decay of its soluble precursor conservative with salinity 238U (t½ = 4.5 109 years). Since 234Th presents relatively short half-life, it is used to quantify processes that occur in temporal scale varying from days to weeks. The disequilibrium 234Th/ 238U in the surface ocean has been applied to estimate carbon fluxes exported via sinking material. The flux of particles biologically productive out of the euphotic zone in the Southern Ocean has special attention due to its importance in the control of CO2 atmospheric concentrations. The radionuclides 210Pb (t½ = 22.3 years) and 210Po (t½ = 138 days) are also particle-reactive. The disequilibrium 210Po/ 210Pb has been used to estimate fluxes of particles exported in the ocean in the time scale of weeks. The long-lived Ra isotopes, 226Ra (t½ = 1,600 years) and 228Ra (t½ = 5.75 years) are soluble in seawater, presenting unique properties that make them excellent tracers of water masses. This research work had the aim to study the distributions of natural radionuclides 238U, 234Th, 226Ra, 228Ra, 210Pb and 210Po in the Bransfield Strait during 2 samplings carried out in the 2011 Austral Summer (OPERANTAR XXIX and XXX).

Full textO presente trabalho aborda as determinações de idades de espeleotemas e corais, usando o método de desequilíbrio da série urânio, mais especificamente, o método de deficiência de filhos daughter deficient DD, em particular o método 230Th/234U. Foram testadas diferentes metodologias empregando separação por extração cromatográfica e quantificação por espectrometria alfa e ICP-MS. Foram testados três procedimentos diferentes: separação em batelada empregando-se colunas com Tri-octil óxido de fosfina (TOPO) em silica- gel e a coluna TRU comercializada pela Eichrom(R), composta de octil-N,N,- isobutil carbamoil óxido de fosfina dissolvido em fosfato de tributila (TBP) e quantificação por espectrometria alfa; separação em batelada com os mesmos sistemas mas quantificação por ICP-MS e separação em linha (flow injection) com cartuchos de TRU e quantificação por ICP-MS. As metodologias desenvolvidas foram validadas empregando-se amostras de referência certificada, IAEA-327 (solo) tendo sido obtidas incertezas de 2% para o método empregando a separação em linha (flow injection) com cartuchos de TRU e quantificação por ICP-MS. As amostras de espeleotema analisadas foram coletadas no Carste de Lagoa Santa, MG, pelo grupo do Prof. Luis Piló (USP) e suas idades variaram de 15,2±2,2 kanos a >350 kanos. Estes valores estão na faixa dos valores encontrados na literatura para amostras de espeleotema coletadas pelo mesmo grupo na mesma região. A amostra de coral, coletada na Bacia de Campos (RJ) era da espécie Lophelia pertusa, foi subdividida segundo suas ramificações (primária, secundária e terciária) e o ramo principal foi datado em 9,4 ± 0,3 kanos.
This paper discusses the age determination of speleothems and corals using Uranium-series- imbalance method, more specifically the daughter deficient method - DD, particularly the 230Th/234U method. Different methodologies were tested using chromatographic extraction separation and quantification by alpha spectrometry and ICP-MS. Three different procedures were tested: batch separation using columns with Tri-N-Octylphosphine Oxide (TOPO) in silica gel and TRU column commercialized by Eichrom(R) composed of octyl-N,N,-isobutyl carbamoylphosphine oxide dissolved in tri-n-butyl phosphate (TBP) and with quantification by alpha spectrometry; batch separation with the same systems, but with quantification by ICP-MS; and flow injection with TRU cartridges and qualification by ICP-MS. The methodologies developed were verified using certified reference samples, IAEA-327 (soil) with 2% imprecision rate for the method using flow injection with TRU cartridges and qualification by ICP-MS. The speleothem samples analyzed were collected at Carste de Lagoa Santa, in the state of Minas Gerais, by Prof. Luis Piló`s (USP) group, and their ages varied from 15,2±2,2 kyears to >350 kyears. These numbers are within the range found in the literature for speleothem samples collected by the same group in the same region. The coral sample, collected at Bacia de Campos (RJ), and from the Lophelia pertusa species, was subdivided according to its ramifications (primary, secondary and tertiary), and the main ramification dated 9,4 ± 0,3 kyears.

This thesis describes the cloning and analysis of PER6, a gene required for peroxisome biogenesis in Pichia pastoris. The gene was cloned by functional complementation of a per6 P. pastoris mutant strain that was one of a number of peroxisome-deficient mutants isolated in this laboratory. The complementing activity was localized to a small DNA fragment by subcloning and Northern filter hybridization analysis and the DNA sequence of the fragment was determined. The sequence revealed a 1296-bp open reading frame which potentially encodes a 432-amino acid protein of 49 kD. The gene was transcribed into a message of 1.4 kilobases that was constitutively expressed but induced several-fold in cells growing on methanol. A mutant strain with a deletion of a large portion of the open reading frame was constructed and used to genetically demonstrate that the cloned gene was identical to the defective gene in the originally isolated per6 mutant. The predicted amino acid sequence of the PER6 product revealed several interesting features, including a significant regional similarity to PAF-1, a gene known to be defective in some patients with Zellweger syndrome, a lethal human genetic disease caused by peroxisome deficiency. Finally, the PER6 product was produced in E. coli and purified to serve as antigen for antibody production.
