Niobium filtration of conventional and high-frequency x-ray generator beams for intraoral radiography. Effects on absorbed doses, image density and contrast, and photon spectra
We have studied the effects of niobium beam filtration on absorbed doses, on image density and contrast, and on photon spectra with conventional and high-frequency dental x-ray generators. Added niobium reduced entry and ...
Comparison of different dosimetric methods for red marrow absorbed dose calculation in thyroid cancer therapy
(OXFORD UNIV PRESSOXFORD, 2012)
Several dosimetric methods have been proposed for estimating red marrow absorbed dose (RMAD) when radionuclide therapy is planned for differentiated thyroid cancer, although to date, there is no consensus as to whether ...

Study of the spatial distribution of the absorbed dose in blood volumes irradiated using a teletherapy unit
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Blood irradiation can be performed using a dedicated blood irradiator or a teletherapy unit. A thermal device providing appropriate storage conditions during blood components irradiation with a teletherapy unit has been ...
Is it necessary to reduce the radioiodine dose in patients with thyroid cancer and renal failure?
(Sociedade Brasileira de Endocrinologia e Metabologia, 2010)
The objective of this study were to obtain dosimetric data from a patient with thyroid cancer simultaneously undergoing peritoneal dialysis therapy, so as to determine the appropriate amount of 131I activity to be applied ...
Comparison between three promising β-emitting radionuclides, 67Cu, 47Sc and 161Tb, with emphasis on doses delivered to minimal residual disease
(Ivyspring International Publisher, 2016-06)
PURPOSE: Radionuclide therapy is increasingly seen as a promising option to target minimal residual disease. Copper-67, scandium-47 and terbium-161 have a medium-energy β- emission which is similar to that of lutetium-177, ...
Neutron dose estimation in a zero power nuclear reactor
(Pergamon-Elsevier Science Ltd, 2016-10-17)
This work presents the characterization and contribution of neutron and gamma components to the absorbed dose in a zero power nuclear reactor. A dosimetric method based on Fricke gel was implemented to evaluate the separation ...
