Characterization of Geiger-Müller radiation detectors response at the University of Costa Rica's Cyclotron Facilities

To ensure a reliable verification of a radiation detector, the right parameters for this response verification must be determined and a specific characterization on the detectors of interest must be performed. These were the main pillars of this study, where four Geiger-Müller at the University of Costa...

Comparación de la dosis recibida por personal ocupacionalmente expuesto en intervencionismo

El objetivo de esta investigación fue determinar la relación entre la dosis de radiación recibida y la práctica en intervención médica. Se estudiaron estadísticamente los reportes dosimétricos de profesionales que han laborado en intervencionismo con un Arco en C en el Hospital José Carrasco Art...

Radionuclide therapy: current status and prospects for internal dosimetry in individualized therapeutic planning

Clinics; 74 (), 2019
The efficacy and toxicity of radionuclide therapy are believed to be directly related to the radiation doses received by target tissues; however, nuclear medicine therapy continues to be based primarily on the administration of empirical activities to patients and less frequently on the use of internal d...

Biological X-ray irradiator characterization for use with small animals and cells

Braz. j. med. biol. res; 50 (3), 2017
This study presents the characterization of an X-ray irradiator through dosimetric tests, which confirms the actual dose rate that small animals and cells will be exposed to during radiobiological experiments. We evaluated the linearity, consistency, repeatability, and dose distribution in the positions ...

Development of a mouse computational model for MCNPx based on Digimouse (r) images and dosimetric assays

ABSTRACT The aim of this study was to create and test a new mice 3D-voxel phantom named DM_BRA for mice and human first-estimation radiopharmaceutical dosimetry. Previously, the article reviews the state-of-art in animal model development. Images from Digimouse CT database were used in the segmentation a...
