Abstract

Fish from a Funil dam reservoir associated with a Nuclear Fuel Factory were sampled aiming to assess the radiological risk due to ingestion. Funil dam reservoir is a strategic site, once it receives effluent from the industrial complex that performs isotopic enrichment of uranium and conversion of UF₆. The mean activity concentrations obtained for ⁴⁰K, ²²⁶Ra, ²²⁸Ra and ²²⁸Th were 57.81, 0.41, 0.92 and 0.49 Bq·kg^-1, respectively. Lifetime cancer risk was estimated in ∼10^-5 and no action needs to be taken.
