Повний текст джерелаIn the decades of 1960 and 1970, the first investigations of termoluminescentes dosimeters (TLD), specifically, the dosimetric peaks quickly revealed a surprising number of phenomena that could be directly related to the density of ionization. A little later, in the years 80 and 90 at the beginning of the year, seemingly disconnected radiation induced phenomena were discovered on other systems based on lithium fluoride (LiF). The last decade, however, has witnessed the emergence of several models, spearheaded through a deeper understanding of the underlying TL mechanisms as well as in modeling specifically developed for microdosimetric and explain phenomena of ionization density. Many applications in radiation oncology provide levels of radiation dose in excess of 1 Gy, however in diagnostic radiology are in the range of a few mGy, and very high levels of precision are necessary to promote the ideal treatment. This requires careful attention to the highly detailed measurement protocols, as well as the time-consuming calibration of all TLDs to correct the non-linearity of dose-response. These properties can vary from batch to batch, and can also be a function of exposure to radiation, heating and handling history. In this way, even with excellent advances in the studies of the TLD for the heat treatment and the ways of issuing TL curve analysis, it is necessary to continue studies in order to enable a better use of this technique in the clinic. A computerized analysis of the emission curve (CGCA computadorized glow curve analysis) was implemented using data from the WinREMS software of TL dosimeters that absorb and store energy from ionizing radiation, reissued in the form of photon in the visible ultraviolet. The light emitted is then detected by a photomultiplier and correlated to the absorbed dose received by the material. The emission peaks were adjusted by means of an algorithm in MATLAB program by adopting the model of first-order kinetics. The material tested was the LiF: Mg, Ti (lithium fluoride doped with magnesium and titanium) brand Harshaw and the quality of the fit was determined by a parameter called figure of merit (FOM- figure of merit). The smallest FOM obtained for the group of dosimeters was 1.04% and the highest was 9.79%. Also minimum detectable dose was evaluated, using the parameter that showed better performance, according to the homogeneity of the Group of dosimeters. The average value of minimum dose presented was 28 µGy. The results of reproducibility, index of variability of the detector (DVI-English, device variability index) was 14.01%, which can be explained by the high number of dosimeters in the batch. Then, with the decrease in the time of preparation of the dosimeter and the computerized analysis of the emission curve, the clinical use of the TLD becomes more viable, since there was no interference on sensitivity of the dosimeter. Although the reproducibility have been above expectations, indicated a single correction for each badge and the disposal of those who submit more discrepant values compared to the batch.

A Terapia por Captura de Nêutrons, NCT (Neutron Capture Therapy) é uma técnica radioterápica em que a energia útil do tratamento vem da energia liberada em uma reação nuclear e não do feixe primário, como comumente utilizado em outros procedimentos radioterápicos. O Boro, por constituir-se em um elemento de baixa toxicidade e por apresentar um isótopo (10B) com alta seção de choque para a reação 10B(n,α)7Li tem sido o elemento mais utilizado nas pesquisas que visam o aprimoramento e a promoção desta técnica, derivando daí o termo BNCT (Boron Neutron Capture Therapy). Para fins de pesquisa em BNCT foi construída ao longo de um dos extratores de feixes (BH - Beam Hole) do reator IEA-R1 uma instalação, onde filtros e moderadores são posicionados entre o núcleo do reator e a posição de irradiação com o objetivo de modular o feixe de irradiação, otimizando a componente útil do feixe, os nêutrons térmicos, e reduzindo os contaminantes, raios gama e nêutrons em outras faixas energéticas. Tem-se realizado estudos visando a implementação de melhorias na caracterização e otimização do feixe obtido nesse arranjo instalado no BH-3. Atualmente a monitoração dos nêutrons é feita através de folhas de ativação, e a componente gama pelo TLD-400. Uma nova metodologia de monitoração tem sido estudada pelo grupo. A referida técnica consiste em usar TLDs de tipos diferentes, ou seja, que possuam sensibilidades distintas aos nêutrons térmicos, em virtude de diferenças na concentração dos isótopos de Lítio. No estudo dessa nova metodologia têm sido usados os TLD-600 e TLD-700. Este trabalho propõe uma metodologia usando o par TLD-100 e TLD-700. Inicialmente foi verificada a reprodutibilidade das respostas dos TLDs 700, 400 e 100 frente a campos gama puro e campos mistos, gama e nêutron. Campos estes obtidos em arranjos usando fontes de 60Co e 241AmBe. A partir de simulações usando o VI MCNP5 foi projetado e construído um Irradiador de campos mistos, que permitiu expor os dosímetros em campos mistos com diferentes espectros energéticos. As condições criadas no irradiador permitiram verificar, como a resposta do TLD é modificada pelas mudanças no espectro energético de um campo misto gama e nêutrons de baixo fluxo. O irradiador de campo misto permitiu condições para estabelecer uma relação entre o formato da curva termoluminescente e a composição do campo misto. A relação estabelecida relaciona o fluxo relativo e a razão entre a resposta das duas regiões de interesse dos TLDs 700 e 100. A partir de campos mistos com condições controladas, esse trabalho permitiu verificar a viabilidade do uso do par de TLD-100 e TLD-700 para monitoração de nêutrons térmicos na instalação de BNCT.

Повний текст джерелаTematem rozprawy jest badanie wpływu parametrów stymulacji UV i termicznej na emisję światła z detektorów termoluminescencyjnych promieniowania jonizującego, z wykorzystaniem zjawiska termoluminescencji stymulowanej światłem (PTTL: PhotoTransferred ThermoLuminescence), a w konsekwencji – poszukiwanie warunków stymulacji optymalnych ze względu na dokładność ponownego (tzn. wykonywanego po pierwszym odczycie) wyznaczenia dawki. Pomiary były wykonywane z dozymetrami MTS-N (LiF:Mg,Ti) i MCP-N (LiF:Mg,Cu,P) napromieniowanymi promieniowaniem elektromagnetycznym o dawce do 1000 mGy dla MTS-N oraz do 25 mGy dla MCP-N. Za pomocą czytnika TLD Reader-Analyser RA’04 została zbadana zależność wydajności odczytu danych PTTL od długości fali promieniowania UV, czasu ekspozycji i temperatury detektorów w trakcie naświetlania UV. Spośród wszystkich dostępnych długości fal promieniowania UV (254, 302 i 365 nm) najwyższa wydajność detekcji wystąpiła przy λ = 254 nm. Dalsze pomiary były prowadzone ze stymulacją promieniowaniem UV o tej długości fali. Wydajność detekcji z wykorzystaniem zjawiska PTTL była badana przy następujących parametrach stymulacji: – czas ekspozycji na promieniowanie UV połączonej z nagrzewaniem detektorów: od 30 min. do 8 godz. dla detektorów MTS-N i od 10 min. do 4 godz. dla MCP-N, – temperatura ogrzewania w trakcie ekspozycji UV: od 33°C do 140°C dla detektorów MTS-N i od 30°C do 120°C dla MCP-N. Najważniejsze wyniki dotyczą przydatności metody PTTL do powtórnej oceny dawki: wyznaczenie wydajności odczytu PTTL, analiza liniowości wskazań detektorów, oraz wskazanie optymalnych warunków ekspozycji UV i obróbki termicznej detektorów TL. Badania wykazały, że wysoka czułość detektorów MCP-N w rutynowych pomiarach dozymetrycznych nie znajduje odzwierciedlenia w powtórnym odczycie, z wykorzystaniem zjawiska PTTL.
