Full textNational and international health organizations such as the Brazilian Ministry of Health, through its Secretary of Health Surveillance establishes in the publication Nº 453/98 that in all mammographic equipments must be evaluated the entrance-skin dose through the readings of an ionization chamber-electrometer system corrected by the backscatter factor, among others factors. Nevertheless, there is no explicit mention for useful values of backscatter factor in this document; the main aim of this work is the experimental determination of backscatter factor through the use of TLD-100 dosimeters. In this study, the geometric and spectral dependencies of the backscatter factor, entrance-skin dose and the in-depth dose were evaluated, corresponding to the most radiographic techniques employed in conventional mammographic procedures, i.e., beam qualities in the range of 0.35 mmAl to 0.43 mmAl, tube voltages from 25kV to 32kV, focus-film distances from 56cm to 66cm, and three field sizes were evaluated. Our results were compared with those previously published obtained through Monte Carlo simulation, ionization chambers and TLD dosimeters. The results obtained in this work allow studying the dependency of the mentioned dosimetric quantities with the half-value layer, tube voltage, anode-filter combination, field size, focusfilm distance and breasting thickness of the breast.

Full textThis work presents the dose variations obtained when phantoms of different electronic densities were used, simulating fat tissue, muscle, bones and air cavities, comparing experimental data with a 6 MeV photon beams and the values calculated by the treatment planning system algorithms. Thermoluminescent dosimeters were positioned above, inside and below each phantom measuring the dose along the depth and along a profile. The computational simulation was done by two algorithms that are part of Eclipse version 8.5: Pencil Beam Convolution and Analytical Anisotropic Algorithm. Comparing doses at the same point, with and without heterogeneities, percentages of 12% were found when heterogeneity correction was not used. These results also show which of the algorithms approaches better to the experimental values, becoming more reliable.

Full textNeutron Capture Therapy (NCT), is a radiotherapy technique in which the useful treatment energy comes from the energy released in a nuclear reaction and not from the primary beam, as commonly used in other radiotherapc procedures. Boron, an element of low toxicity presents an isotope (10B) with high cross-section for the (n, α) reaction and therefore has been the element mostly used in research aimed at the improvement and promotion of this technique, deriving hence the term BNCT (Boron Neutron Capture Therapy). For BNCT research purposes, a facility was built along one of radiation extractors of the IEA-R1 reactor. In this facility filters and moderators are positioned between the reactor core and the irradiation position aiming to modulate the irradiation beam by optimizing the useful component of the beam, thermal neutrons, and reducing its contaminants, gamma rays and neutrons in higher energy bands. We have conducted studies aimed at implementing improvements in the characterization of and optimization of the beam. Currently, neutron flux monitorion is done through activation foils, and the gamma component by TLD-400. A new methodology has been studied by the group. The technique consists in using different types of TLD, having different sensitivities to thermal neutrons due to differences in the concentration of lithium isotopes. In the study of this new methodology TLD 600 and TLD-700 have been used. This work presents a series of studies in order to apply a methodology using the TLD-100 and TLD-700 pair. TLDs 700, 400 and 100 responses pure gamma and mixed irradiation fields, obtained in arrangements using a 60Co and AmBe sources, were evaluaterd. MCNP simulations were run in order to both discriminating the radiation components and designing one mixed fields irradiator, which allowed exposing dosimeters in mixed fields with different energy spectra. The conditions created in the irradiator allowed to verify, as the TLD response is modified by changes in the energy spectrum of a mixed gamma neutron fields. VIII This irradiator provided irradiation conditions so to establish a relationship between the shape of the LiF glow curves and the composition of the mixed field. This work has shown the feasibility of using the TLD-100 and TLD-700 pair for gamma and thermal neutrons monitoration in the BNCT facility.

Full textIn vivo dosimetry is the ultimate check of the actual dose delivered to an individual patient and has become a procedure actually necessary due to increasing complexity and sophistication of radiotherapy techniques. The purpose of the present work was to present, verify and evaluate some basic, practical and viable procedures for the implementation of in vivo dosimetry with thermoluminescent dosimeters for patient dose verification at a radiotherapy service. For the setting up of the thermoluminescent dosimetric system, several tests and measurements were carried out including the initialisation procedure, the determination of the batch homogeneity, the determination of individual correction factor of each dosimeter, the determination of linearity range of the system and its calibration coefficients. Anthropomorphic phantom measurements were taken to ensure that the methods are satisfactory before they are used for patients measurements. Patient dose measurements were carried out in a prostate cancer treatment. The proposed methodology can be used as a part of a quality assurance program in a radiotherapy service.

Full textBoron Neutron Capture Therapy, BNCT, is a bimodal radiotherapic procedure for cancer treatment. Its usefull energy comes from a nuclear reaction driven by impinging thermal neutron upon Boron 10 atoms. A BNCT research facility has been constructed in IPEN at the IEA-R1 reactor, to develop studies in this area. One of its prime experimental parameter is the beam dosimetry which is nowadays made by using activation foils, for neutron measurements, and TLD 400, for gamma dosimetry. For mixed field dosimetry, the International Commmission on Radiation Units and Measuments, ICRU, recommends the use of pair of detectors with distinct responses to the field components. The TLD 600/ TLD 700 pair meets this criteria, as the amount of 6Li, a nuclide with high thermal neutron cross section, greatily differs in their composition. This work presents a series of experiments and simulations performed in order to implement the mixed field dosimetry based on the use of TLD 600/TLD 700 pair. It also intended to compare this mixed field dosimetric methodology to the one so far used by the BNCT research group of IPEN. The response of all TLDs were studied under irradiations in different irradiation fields and simulations, underwent by MCNP, were run in order to evaluate the dose contribution from each field component. Series of repeated irradiations under pure gamma field and mixed field neutron/gamma field showed differences in the TLD individual responses which led to the adoption of a Normalization Factor. From the use of Normalization Factor the TLD selection it has allowed to overcome TLD selection. TLD responses due to different field components and spectra were studied. It has shown to be possible to evaluate the ralative gamma/neutron fluxes from the relative responses observed in the two Regions of Interest of TLDs glow curves, ROIs, from TLD 600 and TLD 700. It has also been possible to observe the TLD 700 response to neutron, which leads to a gamma dose overstimation when one follows the ICRU recommended mixed field dosimetric procedure. Dose response curves were obtained for the distinct types of TLDs for pure gamma and mixed fields. This work recommends the TLD 600/TLD 700 pair methodology for mixed field dosimetry, this methodology presents a better precision than the one based on TLD 400, however one has to be carefull to avoid gamma dose superestimation.

Full textFor several years, the development of the wireless technologies using the electromagnetic waves in various applications (telecommunications, medical, military …) does not stop increasing. Thus, it becomes necessary to evaluate the effects of the environment on antennas upstream to their conception to optimize the transmission between diverse connected objects. Furthermore, studies on the systems using the electromagnetic waves lead to ask a number of questions about waves/living interaction, obliging us to consider highly heterogeneous models such as human body.In front of difficulties of measures, the simulation allows to quantify numerically the power absorbed by tissues and the corresponding temperature rise. In this domain, the TLM method (Transmission Line Matrix) has proved to be particularly adapted to the simulation of the SAR in highly heterogeneous structures thanks to the co-localisation of the fields at the centre of mesh.In this thesis, a tool based on the TLM method to make dosimetrics studies by calculating the SAR and the temperature in highly heterogeneous media has been developed. The first step was dedicated to the development of a “module” to calculate the SAR and the implementation of an interface to read the voxelized models. Then, a thermal solver based on the TLM was developed in order to simulate the temperature in biological media exposed to the EM waves. Finally, the comparison with the commercial software CST allowed to validate our tool and to apply it afterward to study the exposure of a human head to the radiation of a Smartphone modelled by a PIFA antenna operating at 900MHz
