Resumo: The recent advances and improvements on nuclear medicine area involving diagnostic and therapy tests has called attention of electronic engineers on how to design modern detection probes. The basic modern design targets are related to the size and weight (smaller) and, mainly, to higher detection efficiency. We have built in the past a probe that has been used for diagnostic thyroid exams since 2004 in the Nuclear Medicine Service (NMS) of Universidade Federal do Rio de Janeiro (UFRJ) hospital. However, its design has been made considering that it would be installed and operated just in typical exam rooms of NMS of any hospital. In order to the equipment be easily used in smaller operational rooms, like intensive therapy units (ITU) or hospital rooms, the probe should be light enough and consequently be handled without cause any discomfort to the patient. This goal could be reached by developing a new probe, which has a shielding, and collimator properly designed for this purpose. The aim has been to achieve the better ratio between interest measurement radiation and background radiation with good detection efficiency for a specific geometry. This work will present a source-detection computational simulation considering different compound shielding materials. The simulation will be performed using MCNPX general code considering radiation energy sources most used in thyroid tests.
