The aim of this research was to determine (210)Pb 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 U(3)O(8) were found. The concentrations of (210)Pb 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.
本研究的目的是测定位于佩德拉市和文图罗萨市农场的岩石和土壤中的（210）铅浓度。在这些农场中，发现了富含高比例U（3）O（8）的镁铁质岩石块。岩石样品中（210）铅的浓度在3.2至201 kBq kg（-1）之间，土壤样品中（210）铅的浓度在195至86,400 Bq kg（-1）之间。样品中发现的高放射性水平表明，有必要开展更详细的研究，以评估伯南布哥州民众因饮用牛奶而摄入放射性核素的风险。
