Mosses have been widely used as biomonitors of a variety atmospheric pollutants, including radionuclides. Here we determine the radionuclide activity concentration 210Pb, 137Cs, 7Be, and 40K in moss tissue (Hylocomium splendens) collected from 24 sites across Ireland assess influence precipitation on spatial distribution. Lead-210 was most abundant (range: 226–968 Bq kg–1), followed by 7Be <...

In this work a thorough analysis of the vertical distribution natural and artificial radionuclides trace elements in sediment core sample was conducted. A 39 cm length grabbed from deep-sea trench (1540 m depth) southern Samothrace Island, Aegean Sea. The then treated at Hellenic Centre for Marine Research, separated 1cm increment samples, ranging 0cm to cm, dried, milled. first samples also co...

Saltmarshes, wetlands, inter-tidal mudflats are highly productive natural ecosystems with significant ecological value. 210Pb and 137Cs have been used for establishing chronologies at a centennial scale in these sediments. They relevant assessing how saltmarshes vulnerable to climate change, hazards contamination from human inputs. This paper aims review adapt existing methods the 210Pb-based r...

There are many regulations related to the radiological control of NORMs (Naturally Occurring Radioactive Materials) in activities such as mining, industry, etc. Consequently, it is necessary apply fast and accurate methods measure activity concentrations long-lived natural radionuclides (e.g., 238U, 234,232,230,228Th, 228,226Ra, 210Pb, 210Po, 40K) samples characterized by a wide variety composi...

The richest uranium ore bodies ever discovered (Cigar Lake and McArthur River) are presently under development in northeastern Saskatchewan. This subarctic region is also home to several operating uranium mines and aboriginal communities, partly dependent upon caribou for subsistence. Because of concerns over mining impacts and the efficient transfer of airborne radionuclides through the lichen...

Floodplain sedimentation removes particles from fluvial transport and constructs stratigraphic records of flooding, biogeochemical sequestration and other aspects of the environmental history of river basins-insight that is enhanced by accurate geochronology. The natural fallout radionuclide (210)Pb, often employed to date lacustrine and marine sediments, has previously been used to determine f...
