Validación del blindaje estructural de las salas de radiodiagnóstico e intervencionismo del Hospital de Especialidades Carlos Andrade Marín mediante levantamiento radiométrico bajo el protocolo IAEA/ARCAL XLIX.

Abstract

The main objective is to validate the structural shielding in the radiodiagnostic and intervention rooms of the Carlos Andrade Marín Specialty Hospital, by means of a radiometric survey under the IAEA / ARCAL XLIX protocol. . For which, the most common examinations performed in the different rooms were repeated with the help of an anthropomorphic phantom that simulates the patient. Different points of interest were taken in each room where the Occupationally Exposed Personnel (OEP) and the public are located. The different rooms have conventional x-ray equipment, fluoroscopy, computed tomography and an angiography room with C-arc equipment. Dose rate measurements were taken with a gaseous detector type Radcal RSM ionization chamber, at different distances as walls, floor or ceilings, to later estimate the weekly and annual dose considering variables such as voltage, current, use factor, ionization chamber calibration factor, occupancy factor, weekly workload and the reading obtained. It is concluded that the weekly and annual doses at the different points of interest of each room comply with the permitted dose restriction levels of 0.10 mSv / wk or 5.0 mSv / year for controlled areas and 0.01 mSv / wk or 0.5 mSv / year for uncontrolled areas. It is recommended to maintain the distribution of the rooms so as not to alter the classification of the zones and always have the calibrated equipment.
