Abstract: Precise radionuclide measurements are crucial for absolute dating in paleoclimatic studies. Mazinger, a very-low-level background and high-efficiency γ -ray spectrometer, was upgraded with two anti-muon veto detectors and its acquisition electronics have been reconfigured, both to improve detection limits and handle higher event rates coming from the veto system. The upgrade led to a doubling of Mazinger's figure of merit and significantly reduce the background level. These improvements enhance Mazinger's performance for geochronological applications. Application to 210Pb dating of a low-level activity sediment core from Sobrado Lagoon (Spain) produced an age model with uncertainties under 5%, matching correctly with the 137Cs profile. • Dual anti-muon veto implementation reduced total background level by a factor of 4. • Acquisition electronics reconfigured, doubling the system's figure of merit. • 210Pb dating achieves <5% age uncertainty in low-level sediments. • Age results validated by 137Cs profile.
