A method for the determination of the 210Pbactivity by HPGe spectrometry is proposed, consisting of measuring the bremsstrahlung generated in a sample by 210Bi β-emission (1.16 MeV). The detection efficiency is evaluated by GEANT3 simulation and is compared with experiment. A detection limit of 600 mBq was obtained. This technique has been used to select low background detector materials and lead shielding.< Réduire
