Pb-210 in Rock and Soils of the Semi-Arid Agreste Region of Pernambuco, Brazil

The aim of this research was to determine ²¹⁰Pb concentrations in rocks and soils of farms located in the municipalities of Pedra and Venturosa. In these farms, rolled blocks of mafic rock with a high percentage of U₃O₈ were found. The concentrations of ²¹⁰Pb varied from 3.2 to 201 kBq kg⁻¹ in rock...

Description
Summary:The aim of this research was to determine ²¹⁰Pb concentrations in rocks and soils of farms located in the municipalities of Pedra and Venturosa. In these farms, rolled blocks of mafic rock with a high percentage of U₃O₈ were found. The concentrations of ²¹⁰Pb varied from 3.2 to 201 kBq kg⁻¹ in rock samples and from 195 to 86,400 Bq kg⁻¹ in soil samples. The high levels of radioactivity found in the samples, indicate the need to conduct more detailed studies to evaluate the risk of radionuclide ingestion due to milk consumption by the population in the state of Pernambuco.
