Web1 de may. de 2024 · However, there are still limitations in the modeling of basalts as the characterization of enriched mantle components is incomplete for Sn isotopes. Last, the Sn isotope composition of BSE was estimated from the most primitive peridotite with a δ 124 Sn value of −0.08 ± 0.11‰, this result being in agreement with Sn isotope data for basalts. WebEnvironmental matrices (water, sediments and rocks) from 32 Swedish pit lakes, commonly used for recreational purposes were radiometrically characterized via alpha (238U, 234U, 232Th, 230Th, 210Po isotopes) and gamma spectrometry (238U and 232Th series radionuclides). Additionally, ambient dose rate equivalent in the immediate surrounding of ...
