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 24423 Percepção de risco no processo de trabalho com fontes de radiação2017 - CARNEIRO, J. C. G.; LEVY, D.; SANCHES, M.P.; RODRIGUES, D.L.; SORDI, G.M.A.A.Este estudo discute o risco ocupacional sob três aspectos distintos, que muitas vezes apresentam-se interligados ou são interdependentes no ambiente laboral. São eles: riscos ambientais, falhas humanas e falhas de equipamento. O artigo aborda a exposição potencial no ambiente de trabalho, causada pelo agente do risco físico radiação, resultante do manuseio com fontes de radiação ionizante. Baseado no histórico dos acidentes ocorridos em operações normais, o estudo apresenta um resumo dos principais acidentes em diversas instalações e possíveis causas envolvendo os três aspectos do risco. Em suas considerações finais, apresenta as lições aprendidas e as medidas a serem tomadas com o intuito de contribuir para a prevenção e mitigação dos riscos no ambiente laboral. A análise dos casos de acidentes e suas causas fornecem informações valiosas para a prevenção dos riscos de acidentes similares e contribuem para o aprimoramento dos projetos e procedimentos operacionais.Artigo IPEN-doc 21714 Ambient radiation levels in a microPET/CT research laboratory2015 - SARMENTO, D.M.; RODRIGUES, D.L.; SANCHES, M.P.; CARNEIRO, J.C.G.G.Artigo IPEN-doc 21133 Radiological control of a microPET/CT laboratory2015 - SARMENTO, DANIELE M.; SANCHES, MATIAS P.; CARNEIRO, JANETE C.G.G.Artigo IPEN-doc 20945 Assessment of the radiological control at the Ipen radioisotope production facility2015 - CARNEIRO, JANETE C.G.G.; SANCHES, MATIAS P.; RODRIGUES, DEMERVAL L.; CAMPOS, DANIELA; NOGUEIRA, PAULO R.; DAMATTO, SANDRA R.; PECEQUILO, BRIGITTE R.Artigo IPEN-doc 20944 Follow up of the natural radiation exposure from gamma rays in the city of São Paulo, Brazil2015 - CARNEIRO, JANETE C.G.G.; SANCHES, MATIAS P.; RODRIGUES, DEMERVAL L.; PECEQUILO, BRIGITTE R.S.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.Artigo IPEN-doc 20395 Assessment of the radiological control at the IPEN radioisotope production facility2014 - CARNEIRO, JANETE C.G.G.; SANCHES, MATIAS P.; RODRIGUES, DEMERVAL L.; CAMPOS, DANIELA; NOGUEIRA, PAULO R.; DAMATO, SANDRA R.; PECEQUILO, BRIGITTE R.Capítulo IPEN-doc 16700 Proteção radiológica em ciclotron: instalação e operação2011 - SANCHES, MATIAS P.Resumo IPEN-doc 06163 Background radiation doses at IPEN-CNEN/SP1997 - SANCHES, M.P.; SAHYUN, A.; SORDI, G.M.A.A.; RODRIGUES, D.L.
