A portable hand powered water sterilization device was created to address a portion of the growing epidemic of global water contamination. As being more supply chain independent and having an active dose sensing component that monitors the water to insure sterilization, our device boasts far more than any current off-the-shelf devices. The device is completely hand powered via a hand crank generator. A spermicidal ultraviolet light bulb, rated at 253.7nm (UV-C), was integrated with a common NalgeneTM water bottle. Along with the bulb, UV. dose sensing electronics and a hand crank generator were incorporated as well, with the generator supplying power to both the bulb and the photodiode circuitry. Results show that eradication of common waterborne bacteria, protozoa, and viruses occurs after cranking the generator for approximately 41 seconds in clear water and up to 65 seconds in turbid water. The total weight added to the water bottle was less than a pound.

O Ipen/Cnen-SP possui um Reator de Pesquisa(IEA-R1) em operação desde 1957. Ele utiliza água leve como blindagem, moderador e como fluido refrigerante, o volume desta piscina é de 273m3. Até 1995 a operação do Reator era descontinua, ou seja, operava diariamente sendo desligado no final do dia, a uma potência de 2,0 MW. A partir daquele ano, após algumas modificações de segurança, o Reator passou a operar de forma continua, ou seja, de segunda-feira a quarta-feira sem ser desligado, totalizando 64 horas semanais. A potência também foi aumentando até 4,5 MW em 2012. Em virtude dessas alterações, a saber, operação contínua e do aumento da potência, as doses dos trabalhadores aumentaram e por isso foram realizados vários estudos para diminui-las. Estudos demonstraram que uma das principais limitações para operação de um reator em potência elevada, provém das radiações gama emitidas pelo sódio-24. Outros elementos como magnésio-27, Alumínio-28, Argônio-51, contribuem de forma considerável para a atividade da água da piscina. A introdução de uma camada de água quente em sua superfície, estável e isenta de elementos radioativos com 1,5m a 2m de espessura constituiria uma blindagem às radiações provenientes dos elementos radioativos dissolvidos na água. Estudos de otimização provaram que a instalação da camada quente não era necessária para o regime e potência atual de operação do Reator, pois outros procedimentos adotados eram mais eficazes. A partir desta decisão o serviço de Proteção Radiológica do Reator IEA-R1, montou um programa de avaliação das doses para certificar-se de que elas se mantinham em valores razoáveis baseados em princípios estabelecidos em normas nacionais e internacionais. O intuito deste trabalho é realizar uma análise das doses individuais dos IOE (Individuo Ocupacionalmente Expostos), considerando as mudanças no regime de operação do Reator e sugerir opções de proteção e segurança, viáveis em primeira instância, para reduzir as doses analisadas, visando se chegar aos níveis de referencia de 3 mSv/ano adotados pela instalação em apreço.

Повний текст джерелаBackground and Objectives: To establish whether the profiler 2 scanning system can be used as a substitute for the 3D-water phantom, by comparing the percentage depth doses and beam profiles for both the photons and electron beams, and validating the results using CMS XiO treatment planning system. Methods: Beam data (profiles, percentage depth doses and absolute dosimetry) were acquired for the two systems: (3D-water phantom and profiler 2 scanning system) for beam energies 6 MV and 15 MV photon beams, and 4, 6, 8, 10, 12 and 15 MeV electron beams generated by the Elekta Synergy linear accelerator (linac) for the field sizes of 6 × 6 cm2, 10 × 10 cm2, 14 × 14 cm2, 20 × 20 cm2, and 25 × 25 cm2 at depths of 0.5 cm, 1.0 cm, 2.0 cm, and 5.0 cm respectively. These measurements were acquired using ionization chambers in water and diode detectors in Perspex. The acquired data was sent to CMS XiO treatment planning system for validation. Results: In general, the dose distributions for both systems compared very well with uncertainties within recommended limits. The largest maximum difference in symmetry was 1.6 % for a 6 MV photon beam defined at 25 × 25 cm2 field size. The largest maximum difference in flatness was 2.77 % for a 4 MeV electron beam defined at 10 × 10 cm2 applicator size. The penumbra largest maximum difference was 1.708 cm for 8 MeV electron beam defined at 25 × 25 cm2 applicator size, which was outside the recommended limit of 1.2 cm. The largest maximum difference in field size was 2.388 cm for a 6 MeV electron beam defined at 20 × 20 cm2 applicator size, which was outside the recommended limit of 0.4 cm. The largest maximum difference in percentage depth dose at 10 cm depth was 1.69 % for the 6 MV photon beam. The absolute dose output measurements showed a very good agreement between the two systems to a maximum percentage difference and highest standard deviation of -0.99 % and 0.69 % respectively for the 6 MV photon beam. Validation measurements showed an agreement to less than 1 % and 2 mm for percentage depth doses and beam profiles respectively. Conclusion and recommendation: From the results obtained, it is evident that the profiler 2 scanning system can be used as a substitute for the 3D-water phantom beam data acquisitions during linear accelerator commissioning. The future work based on this study could be to study the limitations involved with the profiler 2 scanning system when used during measurements for commissioning of a linear accelerator. Limitations like field size (maximum field size of 20 × 30 cm2 at SSD = 100 cm), number of Perspex slabs to be used on top of the profiler 2 scanning system and diagonal profile measurements.

Повний текст джерелаThis paper presents the analysis of the results obtained by means of bibliographic research on the use of water resources in the Guarapiranga River Basin in the metropolitan region of São Paulo, whose use is the priority Utilities. It identifies the impacts caused by the occupation both disorderly, as the overlapping of the other uses incompatible with the maintenance of their quality and quantity, existing in diagnoses made, in order to assess the distortions in the economic valuation of environmental damage. For valuation of these impacts was adopted the methodology of marginal productivity, where the role of the environmental resource in the production process is represented by a dose-response function, which relates the level of provision of the environmental resource (water gross) to the production of their product on the market (treated water). The application of this function allows the measurement of impact on the production system, given a marginal variation in the provision of environmental goods or services, and from this change, one can estimate the economic value of resource usage environment.

Повний текст джерелаDans ce travail nous avons développé deux nouveaux détecteurs qui visent à améliorer l'exactitude de la dosimétrie relative et de référence en radiothérapie: une chambre d'ionisation liquide gardée (GLIC) et un calorimètre d'eau scellé pour les électrons (ESW). Avec la GLIC nous avons visé à développer un détecteur indépendant de l'énergie et libre de perturbations avec une résolution spatiale élevée pour la dosimétrie relative. Nous avons atteint une stabilité suffisante pour des mesures à court terme en utilisant la GLIC-03, qui a un volume sensible d'approximativement 2 mm3. Nous avons évalué la recombinaison générale des ions dans des faisceaux de photons pulsés en utilisant un modèle théorique et nous avons également déterminé une nouvelle méthode empirique, permettrant de corriger pour les différences relatives de recombinaison générale, qui pourrait être employée dans les cas où le modèle théorique ne serait pas applicable. La dépendance d'énergie du GLIC-03 était 1.1% dans des faisceaux de photon entre 6 et 18 MV. Les mesures dans la région de déséquilibre électronique ('build-up') d'un faisceau du 18 MV ont indiqué que ce détecteur introduit une perturbation minimale du champ de rayonnement et ont confirmé la validité de la correction empirique de recombinaison. Le calorimètre ESW a été conçu pour mesurer directement la dose absorbée dans les faisceaux d'électrons cliniques. Nous avons obtenu des mesures reproductibles pour des faisceaux de 6 à 20 MeV. Nous avons déterminé les corrections nécessaires pour tenir compte des perturbations du champ de rayonnement introduites par le récipient de verre du calorimètre et du transfert thermique de conduction dû au gradient de dose et au fait que les matériaux ne sont pas de l'eau. L'incertitude globale sur la dose pour le calorimètre ESW était 0.5% pour les faisceaux de 9 à 20 MeV et 1.0% pour 6 MeV, prouvant pour la première fois que le d

Повний текст джерелаThe aim of this study was to evaluate the circulating levels of F and Pb, as well as the levels of F and Pb excreted and uptaken by bone, in rats co-exposed to F and Pb from the drinking water, taking into account different doses of Pb and F and two types of fluoridated salts. For this purpose, 280 male Wistar rats were divided into 28 groups (n=10). The differences among the groups were the concentrations of Pb (0, 1 , 10 or 30 mg/L ) and F [0, 5, 50 or 100 mg/L in two types of salts (NaF or H2SiF6)] added in the drinking water to which the females and their offspring were exposed, 1 week before mating until the pups completed 80 days of life. At 80 days of age, the animals were euthanized. Blood was collected for Pb and F analysis (whole blood and plasma, respectively). The right femur was also collected for Pb and F analyses. In addition, throughout the experimental period, urine and feces were collected from the animals housed in metabolic cages (n=6/group) every 14 days, for F and Pb analyses. Pb was analyzed by ICP-MS and F was measured with the electrode, after hexamethyldisiloxane-facilitated diffuson (plasma, femur and feces) or by the direct method (urine). Data were analyzed by 3-way ANOVA and Tukey´s test (p<0.05). It was observed that the F compound, the F concentration and the Pb concentration in the drinking water interfered in the retention of Pb and F in the organism. These data indicate that co-exposure to F and Pb from the drinking water increases the F and Pb uptake by bone. This cannot be completely explained by the urinary and fecal excretion of F and Pb. When F was added to the water as H2SiF6, significantly higher F concentrations were observed in plasma and bone, while significantly lower amounts of F were excreted through urine, increasing the bioavailability of F in the organism. Also higher bioavailability of Pb was observed upon administration of H2SiF6 when compared to NaF (significantly higher concentrations of Pb were observed in bone, despite the excretion of Pb from feces and urine was higher). These results reinforce the findings of previous epidemiological and proof-of-concept studies that report increased bioavailability of Pb and F in the organism upon coexposure to silicofluorides and Pb. Additional studies should be conducted to investigate the mechanisms that lead to these effects.

Повний текст джерелаLNE-LNHB current references for medium energy X-rays are established in terms of air kerma. Absorbed dose to water, which is the quantity of interest for radiotherapy, is obtained by transfer dosimetric techniques following a methodology described in international protocols. The aim of the thesis is to establish standards in terms of absorbed dose to water in the reference protocol conditions by water calorimetry. The basic principle of water calorimetry is to measure the absorbed dose from the rise in temperature of water under irradiation. A calorimeter was developed to perform measurements at a 2 cm depth in water according to IAEA TRS-398 protocol for medium energy x-rays. Absorbed dose rates to water measured by calorimetry were compared to the values established using protocols based on references in terms of air kerma. A difference lower than 2.1% was reported. Standard uncertainty of water calorimetry being 0.8%, the one associated to the values from protocols being around 3.0%, results are consistent considering the uncertainties. Thanks to these new standards, it will be possible to use IAEA TRS-398 protocol to determine absorbed dose to water: a significant reduction of uncertainties is obtained (divided by 3 by comparison with the application of the IAEA TRS-277 protocol). Currently, none of the counterparts’ laboratories own such an instrument allowing direct determination of standards in the reference conditions recommended by the international radiotherapy protocols

Повний текст джерелаNowadays, low to medium energy X-ray irradiators are starting to replace irradiators using radioactivesources, mainly in the fields of blood irradiations, Sterile Insect Technique and food irradiations. A dosimeter is placed on the irradiated product to ensure that the desired dose is well delivered. One of the dosimetry systems that is used in radiation processing is the alanine/EPR dosimetry system. Alanine is considered as water equivalent, from a dosimetric point of view for photon energies that are higher than 200 keV. However, it loses its water equivalency for lower photon energies.This thesis presents the use of alanine for the control and validation of irradiation processes performed with low to medium energy X-rays, as well as different methods developed to determine corrective factors to be applied to the response of this dosimeter. These methods are based on experimental measurements, Monte Carlo simulations and analytical calculations

Повний текст джерелаEntre os diversos métodos de aproveitamento da água adotados pela humanidade, o que mais utiliza recursos hídricos é a agricultura através do procedimento da irrigação, permitindo os cultivos agrícolas em um espaço mais abrangente e sendo capaz de atender a demanda por alimentos tanto para consumo humano como consumo animal. Este trabalho apresenta o conceito de Pegada Hídrica (water footprint) que é a quantidade de água, direta e indiretamente, usada na produção de um produto. A pegada hídrica é dividida em três componentes: Verde, Azul e Cinza. O objetivo deste estudo foi determinar os valores da pegada hídrica dos componentes azul e verde para a produção da batata-doce através do método tradicional utilizando o modelo CROPWAT durante os anos de 2010, 2011 e 2012. O trabalho desenvolveu-se no Perímetro de Irrigação Poção da Ribeira (PIPR) pertencente à Companhia de Desenvolvimento de Recursos Hídricos e Irrigação (COHIDRO), localizado nos municípios de Itabaiana e Campo do Brito, em Sergipe. Os resultados obtidos evidenciaram que a Pegada Hídrica verde em 2010, 2011 e 2012, foi de 494,75 (m³/ton), 672,13 (m³/ton) e 402,81 (m³/ton) respectivamente. Já a Pegada Hídrica azul em 2010, 2011 e 2012 foi de 351,1 (m³/ton), 448,4 (m³/ton) e 570,06 (m³/ton) respectivamente. Os resultados obtidos mostraram que há relação entre os índices médios de produtividade da cultura com um maior consumo de água refletindo em maior Pegada Hídrica, que há influência da precipitação na Pegada Hídrica da batata-doce e que não há relação direta entre os índices de produtividade com as variáveis meteorológicas utilizadas no cálculos da Pegada Hídrica.

Повний текст джерелаThe aim of this work was to study the long-lived Ra isotopes, 226Ra and 228Ra, natural distribution in mineral and spring waters from Caxambu (MG) and Águas de Lindóia (SP) waterparks. In Caxambu mineral waters it was observed 228Ra acitivity concentrations slightly higher than those of 226Ra. The elevated content of carbonates and bicarbonates of these waters can result in an increased solubility of the both Ra isotopes and may play an important role for the fate of 228Ra and its equilibrium distribution between solid and liquid phases. In Caxambu Thermal Spa, arithmetic mean activities ranged from 83 mBq L-1 to 3599 mBq L-1 and from 60 mBq L-1 to 4481 mBq L-1 for 226Ra and 228Ra, respectively. The highest 226Ra activity was found in Venancio Spring, while the maximum 228Ra activity value was determined in Ernestina Guedes. 228Ra/ 226Ra activity ratios varied from 0.079 (Conde DEau and Princesa Isabel Spring) to 4.2 (Mairink II Spring). In Águas de Lindóia, arithmetic mean activities ranged from 4.6 mBq L-1 to 41 mBq L-1 and from 30 mBq L-1 to 54 mBq L-1 for 226Ra and 228Ra, respectively. The maximum 226Ra activity concentration was found in the bottled mineral water São Jorge, while the higher 228Ra activity concentration was determined in Santa Filomena Spring (public station 2). 228Ra/ 226Ra activity ratios varied from 1.2 (bottled mineral water São Jorge) to 9.1 (bottled mineral water Jatobá 1). This work also performed the dose assessment due to the ingestion of 226Ra and 228Ra in Caxambu and Águas de Lindóia mineral and spring waters. The committed effective doses were estimated by using a conservative dosimetric model and taking into account the results over a lifetime (70 years) following intake of both long-lived Ra isotopes. The results from this radiological evaluation showed that the guindance committed effective dose level of 0.1 mSv y-1 recommended by World Health Organization was exceeded in almost all samples studied in Caxambu, except for Viotti Spring, Dom Pedro Spring and Dona Leopoldina Spring. In Águas de Lindóia and Lindóia, the highest committed effective doses estimated were 8.4 10-3 mSv y-1 for the intake of 226Ra (bottled mineral water São Jorge) and 2.6 10-2 mSv y-1 for 226Ra (Santa Filomena spring station 2). Both values are below the limit recommended by World Health Organization. The maximum commited effective doses per year obtained in this work were 7.4 10-1 mSv y-1 for 226Ra (Venancio Spring) and 2.2 mSv y-1 for 228Ra (Ernestina Guedes Spring). Considering the case of 226Ra intake via mineral water, the dose obtained represents less than 31 % of the average effective dose attributable annually from natural background radiation. However, in the case of 228Ra the annual committed effective dose limit recommended by ICRP (considering all sources of radiation exposure for the world population) was exceeded not only in Ernestina Guedes Spring, but also in Beleza Spring.
