摘要

Natural radionuclides in the oil industry have been recognized for decades, especially 222Rn from internal pipe scaling processes. At the Abreu e Lima refinery in Pernambuco, 226Ra and its descendant, 210Pb, were monitored to detect radon leaks. A pre-operational survey at the Suape Industrial Port Complex in Brazil detected elevated levels in soils of 210Pb (40.8–622.9 Bq kg⁻1) and 226Ra (5.52 -150.5 Bq kg⁻1) and in sediments of 210Pb (121.4–284.9 Bq kg⁻1) and 226Ra (13.8–55.3 Bq kg⁻1). The observed isotopic ratio indicates excess radiogenic lead, confirming anthropogenic interference and validating isotopic analysis for environmental monitoring.
