Determining the age of geological material is a fundamental issue for reconstructing environmental changes. A recent article co-authored by Sambor Czerwiński compares different models used in dating peats by lead (Pb-210 isotope). Independent methods verified dating results: radiocarbon (C-14) and plutonium isotopes (Pu-239+Pu-240). The study was conducted on different peatlands, analyzing how the Pb-210 isotope was deposited on their surface over time. In the future, this may help improve age-depth modeling of material taken from peatlands.
