摘要

The values of effluent releases to urban sewage system in Brazilian regulation were investigated and compared with the current International Atomic Energy Agency recommended criteria, using the city of Rio de Janeiro as a case study. Deterministic and probabilistic assessments were performed for two conservative scenarios, considering the exposure of the population in general and the exposure of workers in sewage treatment plants. The results from the deterministic assessment were found to be more restrictive than those from the probabilistic assessment. Although currently the doses for the inhabitants of Rio de Janeiro are lower than the dose limit for the public, the approach currently in use in Brazil is not adequate to fulfill the international requirements and nuclide-specific values needing to be adopted.
