Bayesian analysis of 210Pb dating [PDF]
, 2017 In many studies of environmental change of the past few centuries, 210Pb dating is used to obtain chronologies for sedimentary sequences. One of the most commonly used approaches to estimate the ages of depths in a sequence is to assume a constant rate ...

Beryllium 7 and Lead 210 in the western hemisphere Arctic atmosphere: Observations from three recent aircraft-based sampling programs [PDF]
, 1992 Concentrations of the natural radionuclides 7Be and 210Pb were determined in aerosol samples collected in the western hemisphere Arctic during the recent NOAA Arctic Gas and Aerosol Sampling Program (AGASP 3) and NASA Global Tropospheric Experiment ...

Sedimentary processes in the Thau Lagoon (France): From seasonal to century time scales [PDF]
, 2007 As a part of the MICROBENT programme, an investigation of the sedimentation framework was carried out at the water-sediment interface in the Thau Lagoon (French Mediterranean coast). Two main sites, C4 in the middle of the lagoon and C5 near oyster farms,

210Pb- 226Ra chronology reveals rapid growth rate of Madrepora oculata and Lophelia pertusa on world's largest cold-water coral reef [PDF]
, 2012 Here we show the use of the 210Pb- 226Ra excess method to determine the growth rate of two corals from the world's largest known cold-water coral reef, Røst Reef, north of the Arctic circle off Norway.

Chronologies for Recent Peat Deposits Using Wiggle-matched Radiocarbon Ages: Problems with Old Carbon Contamination [PDF]
, 2005 Dating sediments which have accumulated over the last few hundred years is critical to the calibration of longer-term paleoclimate records with instrumental climate data.

A 200-year 210Pb record from Greenland [PDF]
, 1997 A continuous profile of 210Pb activity extending back to 1766 has been developed for a firn/ice core collected at Site D in central Greenland in 1984. Unexpectedly high activities of 210Pb were found at the base of this core (0.032 pCi kg−1 in samples ...

Application of the radionuclide 210Pb in glaciology – an overview
Journal of Glaciology, 2020 210Pb is an environmental radionuclide with a half-life of 22.3 years, formed in the atmosphere via radioactive decay of radon (222Rn). 222Rn itself is a noble gas with a half-life of 3.8 days and is formed via radioactive decay of uranium (238U ...

210Pb numa região anômala de Pocinhos-Paraíba
Brazilian Journal of Radiation Sciences, 2018 From 1979 to 1982, the extinct company NUCLEBRAS carried out studies on the occurrence of uranium in Pocinhos, a city located in the harsh region of the State of Paraíba, where dairy farms currently exist.
