13. Controle de qualidade e dose de entrada na pele em serviços de mamografia de Minas Gerais
Em exames que fazem uso da radiação ionizante, a dose a que o paciente é exposto deve ser mantida tão baixa quanto possível, de acordo com os princípios da proteção radiológica, porém sem comprometer a qualidade da imagem, que vai possibilitar o seu uso como ferramenta útil para o diagnóstico. A obtenção de imagens com definição e contraste s

14. Modelo experimental de tumor no pulmão com implante de células tumorais por via intrabrônquica: avaliação dos efeitos da Talidomida, Gefitinib e Paclitaxel / Experimental model of tumor in the lung with implantation of tumorais cells for saw intrabrônquica: evaluation of the effect of the Talidomida, Gefitinib and Paclitaxel
Lung cancer has been the main cause of death from cancer worldwide over the past decade in spite of the appearance of new chemotherapy drugs and targeted therapies. It is therefore necessary to clarify the molecular and biological changes involved in carcinogenesis and tumor growth and to develop experimental models for the study of the biology of lung tumor

15. Estudo da resposta de cristais de quartzo natural para dosimetria termoluminescente
In the last few years, a number of studies have been carried out with the objective of characterizing and/or developing materials with thermoluminescence properties (TL) for the purpose of ionizing radiation dosimetry. The aim of this study consists in the characterization of the thermoluminescence properties of natural quartz crystals, to be used for radiat

16. Individual monitoring for external exposures: experimentation and simulation with Monte Carlo Method / Monitoração individual externa: experimentos e simulações com o método de Monte Carlo
In this work, we have evaluated the possibility of applying the Monte Carlo simulation technique in photon dosimetry of external individual monitoring. The GEANT4 toolkit was employed to simulate experiments with radiation monitors containing TLD-100 and CaF2:NaCl thermoluminescent detectors. As a first step, X ray spectra were generated impinging electrons

17. Implementação de Grandezas Operacionais na Monitoração Individual e de Área / Implementation of new operational quantities in the Individual and area monitoring
Operational quantities have been implemented to be applied in individual and area routine monitoring against external radiation exposure. This procedure is based on the use of an ideal combination of thermoluminescent detectors inside a monitor: two pellets of CaF2, one covered by a lead filter of (0,50 ± 0,05) mm and another one without filter and one TLD-
