Análisis de la tasa de dosis ambiental en instalaciones hospitalarias en la ciudad de Riobamba, que brindan servicio de rayos x y tomografía computarizada

Abstract

This research was developed in five hospital institutions in the city of Riobamba, with the aim of analyzing the environmental dose rate in X-ray facilities (RX) and Computed Tomography (CT). The procedure proposed in report 147 of the National Council for Radiation Protection and Measurements (NCRP) and protocol XLIX of the Regional Cooperation Agreement for the Promotion of Nuclear Science and Technology in Latin America and the Caribbean (ARCAL) were considered. In each of the institutions, the areas of interest were considered, in which; The critical points were chosen according to the primary and secondary barrier in the case of RX and the secondary barrier in CT. Using a brand-name Geiger Müller detector Gamma Scout Online, the dose rate was measured when the X-ray and CT equipment performed a shot with the highest parameters used in a study, taking four data from the value higher than the detector measures. With the analysis of the results obtained, it is evident that the five hospital facilities, both XR and CT, are within the dose limits by the ARCAL XLIX and the NCRP. In addition, it is recommended to include a radiation protection officer in the facility 4.
