Depth-age model of sediment core FOX12-02R
A chronology was developed using ²¹⁰Pb excess (²¹⁰Pbₓₛ; T1/2 =22.3 yr) and ¹³⁷Cs (T1/2=30 years). Sediment samples were freeze dried, powdered and measured for radioisotopes on a low-background, well- type germanium detector. Activities of ²¹⁰Pb, ²²⁶Ra, and ¹³⁷Cs were corrected for self-adsorption and decay since core collection. The constant flux-constant sedimentation (CF-CS) approach was applied.
