RESUMO
The main purpose of this study was to analyze, at the Gerência de Aceleradores Cíclotron (Management of Cyclotron Accelerators) at IPEN, the control of ionizing radiation doses and their distribution by comparing their values with regulatory requirements. The analysis of the dose rate for the area monitoring was carried out from the data obtained during the production of Fluorine-18 from January 2010 to December 2011, totalizing 1011 measurements at each monitored spot. The doses analysis was performed through consultation of the individual dose records. During the years 2007 to 2011 the records of individual effective doses were analyzed, adding up to 91 records; from 2009 to 2011 the records of equivalent dose (hands) were analyzed, totalizing 49 records. The occupationally exposed individuals involved in the study were classified in three groups according to their task: targets, radioprotection and operation and maintenance. The results of occupational exposure levels of radiation were analyzed and compared with values established in national standards and international recommendations. Based on the results of the area monitoring and the doses received and recorded, radiation protection procedures implemented at the facility during the study period were checked and suggestions for improvements were given from the point of view of radiological protection.
