摘要：
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.
