Resumo
The routine operation of a nuclear or radioactive installation generally involves
the release of radioactive liquid and/or gaseous effluents. At the Nuclear and Energy
Research Institute – IPEN there are several nuclear and radioactive facilities, developing
activities in the field of nuclear energy. IPEN’s Radioprotection Management
has established a radioactive effluent sampling program to determine the amount
of radioactive material (source term) released into the environment and to detect
immediately any unplanned release above the pre-established operating limits. The
IPEN Environmental Radiological Monitoring Program – ERMP evaluates the levels
of radioactivity to which individuals of the public are exposed through the analysis
of atmospheric samples; the main objective of an ERMP is the confirmatory radiological
control, which estimates whether the assumptions made in the calculation of
the dose, from the source term, are correct. The objective of the present work is to
present the gaseous radioactive effluents control and the radioactivity assessment in
the atmospheric air at IPEN’s campus, since there were implanted in 1988 at the Laboratory
of Environmental Radiometry of IPEN. In both, gaseous radioactive effluents
control and radioactivity assessment in the atmospheric, cellulose and charcoal cartridge
filters are analyzed by gamma spectrometry – HPGe weekly, from the IPEN’s
radioactive facilities, Accelerators and Cyclotron Center, IEA-R1 Research Reactor
Center, Radiopharmacy Center - Building I and II and each 15 days collected from
three air samplers located near the nuclear and radiation facilities of IPEN, respectively.
The radionuclides determined in the majority of the samples throughout the
sampling period were 131I, 18F and 67Ga.
