Artigo IPEN-doc 23677 Basic characterization of a radioactive facility and evaluation of risk agents2016 - CARNEIRO, J.C.G.G.; ALVES, A.S.; SANCHES, M.P.; RODRIGUES, D.L.; LEVY, D.S.; SORDI, G.M.A.A.This is an exploratory and descriptive study with qualitative and quantitative approaches to investigate the basic characterization of a Brazilian radioisotope production facility through ample knowledge of the workplace, workforce, task performed and identification of present risk agents in labor environment. The studied sample was composed by 102 workers distributed in eight work processes. Data were collected from April 2013 to July 2014 by applying questionnaire forms and complemented by interviews and observations. The descriptive statistical analysis included ANOVA test and non-parametric tests, among others. For the purpose of this study, there was adopted a significance level of 5% (p<0.05). The analysis of socio-demographic variables demonstrated that male gender predominated in total sample (74.5%) and the mean age of the workers was (51.8 ± 1.7) years. The largest percentage of the responders (70.6%) was technician-level workers. Regarding task-related exposure, there was considered that all groups presented the same exposure profile. At the workplace, there were identified 17 risk agents, including physical, chemical, biological, ergonomic and accident risks. The workforce was categorized into 3 risk groups according to relative frequency distribution of the occupational risks. Among the sixteen qualitative variables studied at the workplace, only three of them did not demonstrate relative frequency. The only variable that showed association with the three risk groups was the possibility of the contact with ionizing radiation. The study provided an overview of the perception of occupational risk at the facility. According to the results obtained by statistical analysis, most of the qualitative variables presented statistically significant association (p<0.001) related to the occurrence of occupational risks. Even though the workers may be potentially exposed to different risk agents, the ionizing radiation was the main physical risk factor observed in this facility.Artigo IPEN-doc 20444 Radiation dose impact on the workers from the radiopharmaceutical facility2014 - CARNEIRO, J.C.G.G.; SANCHES, M.P.; RODRIGUES, D.L.; SORDI, G.M.A.A.Resumo IPEN-doc 15979 Impacto das doses efetivas em função do aumento da produção de radiofármacos do IPEN2010 - CARNEIRO, JANETE C.G.; SANCHES, M.P.; RODRIGUES, D.L.; SORDI, GIAN M.A.A.Artigo IPEN-doc 05710 Occupational health experience in the production and distribution of radionuclides used in medicine1994 - GABURO, J.C.G.; SANCHES, M.P.; SORDI, G.M.A.A.Artigo IPEN-doc 16593 Exposição do público devido ao transporte de radiofármaco2011 - RODRIGUES, DEMERVAL L.; CARNEIRO, JANETE C.G.G.; SANCHES, MATIAS P.; SORDI, GIAN M.A.A.Artigo IPEN-doc 16592 Occupational exposure to ionizing radiation associated with the production of radioisotopes2011 - CARNEIRO, JANETE C.G.G.; SANCHES, MATIAS P.; RODRIGUES, DEMERVAL L.; SORDI, GIAN M.A.A.Artigo IPEN-doc 16250 Evaluations of levels and trends of occupational exposure in a Brazilian radiopharmaceutical facility2010 - CARNEIRO, JANETE; SANCHES, MATIAS; RODRIGUES, DEMERVAL; SORDI, GIAN M.Artigo IPEN-doc 18500 Occupational exposure and dose distribution in a brazilian radiopharmaceutical facility2012 - CARNEIRO, JANETE C.G.G.; SANCHES, MATIAS P.; RODRIGUES, DEMERVAL L.; SORDI, GIAN M.A.A.Artigo IPEN-doc 11928 Alternative optimized shipping system in the operations of radioactive materials production2007 - FONSECA, LIZANDRA P.S.; SORDI, GIAN M.A.A.; SANCHES, MATIAS P.The optimization principle in radioprotection must indicate that exist a rational balance between the monitoring exposures resources used and the benefit waited for the monitoring program. The personal doses estimates displayed to the ionizing radiation caused by the shipping system operations of radioactive materials are an important tool in the process of radioprotection optimization. For the doses estimate they will be used models that consider the requirements established for the International Commission of Radiological Protection - ICRP and the Radiopharmaceutical Center monitoring program data. The methodology used for the election of the options of radiological protection that contribute for the reduction of the personal doses involves the criteria of decision aid techniques. The main intention of this work is to establish an alternative consistent procedure that assure. the reduction of the doses, when they will be necessary, is trustworthy, and simplest possible and that it presents indispensable quality established in the applicable standards.Artigo IPEN-doc 14092 Social demographic profile and dose evaluation of the radiopharmaceutical facility workers2009 - SANCHES, MATIAS P.; CARNEIRO, JANETE C.G.; SORDI, GIAN M.A.A.
