- Study of emission of radioactive gaseous effluents in the production of 18F-FDG Heber Simões Videira Ronielly de Lima Santos Marcos Aurélio Vieira Eliane Fernanda Dias Marcelo Kaminski Lenzi Daniel Henrique Uzueli Rubens Abe Maria Inês Calil Cury Guimarães Uysha de Souza Fonda Emerson Nobuyuki Itikawa Miriam Roseli Yoshie Okamoto Carlos Alberto Buchpiguel Beatriz Luci Fernandes Biología Medical physics Monitoring air flow Radiopharmaceuticals PET Radioactive Air Contamination The number of cyclotron facilities producing radiopharmaceuticals with a half-life less than two hours has increased with the development of PET technology in Brazil. The gaseous waste, or gaseous effluent, is formed in the production of these radiopharmaceuticals such as 18F-FDG (half-life = 109.8 min) or 11C-PIB (half-life = 20.4 min). The International Atomic Energy Agency (IAEA) proposes a methodology to evaluate the dispersion of these gaseous effluents. This evaluation is utmost to guarantee that the overall emitted radioactivity be according to the limits established by CNEN (Nuclear Energy National Commission). This work has retrospectively evaluated the emission of radioactive gaseous effluents as a result of the production of 18F-FDG to delimit yield-values of gaseous-form-radioactive waste in thirty-six 18F-FDG production processes. We also verified the effectiveness and the design of the safety elements of the exhaust system evaluated according to the CNEN and IAEA recommendations. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280899022 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.7
