Resumo

The activities of Pb-210 and Cs-137 were measured in a sediment core collected from the north-west region of Guanabara Bay, Brazil. On the basis of Pb-210 geochronology, a sedimentation rate of 2 cm year−1 was estimated for the area in recent times. The Cs-137 activity was below the detection limit (0.2−0.8 mBq g−1) in all depths of the core.
