Diseño e implementación de un programa de vigilancia radiológica de zonas en la Unidad de Medicina Nuclear Convencional del Hospital Carlos Andrade Marín IESS-Quito.

Abstract

The present work had as a fundamental target the design and the implementation of a Radiation Monitoring Program of Areas in the Unit of Conventional Nuclear Medicine of the Hospital Carlos Andrade Marin. The diagnosis of the application of standards and criteria of Radiological Protection determined the scarcity of records, protocols and the irrelevancy of procedures previously established in the above mentioned field. This was the starting point for the design of the Program taking into consideration the analysis of the infrastructure, the Occupationally Exposed Personnel (OEP) and public, the environmental monitoring and the radiological surveillance of every area, the inventory of the open radioactive sources and the creation of a management protocol of radioactive wastes. The areas were organized and classified as a part of the implementation using signaling established under the national and international regulations. The OEP was trained on issues of Radiation Protection and work protocols in each zone, and it was made the monitoring control of the levels of ambient dose rate and surface contamination, also the amount of open radioactive sources that was recorded in the installation was accounted, and it was applied the waste management protocol. As soon as the Program was carried out the variables of ambient date rate and levels of surface contamination were measured in the different controlled areas. It was possible to state the effectiveness of the Program based on the result of the statistical treatment of the values of the analyzed variables resulting in a considerable reduction of the same. Finally the main measures and recommendations derived from the results obtained in the Radiation Monitoring Program of Areas in the Unit of Conventional Nuclear were executed, being part of the action policies of each of the key actors involved in the development of different practices.
