Abstract:
Lead is a common material for gamma-ray shielding but can contribute background signals in rare event searches, such as neutrinoless double beta decay. Single HPGe detectors cannot measure radioactivity below mBq/kg due to self-absorption and lead's high density. This study utilized a fourteen-channel HPGe detector array to measure contaminant activity in lead, accounting for screening effects.
