Abstract: GERDA is an underground experiment designed for the search of neutrinoless double beta decay of 76Ge in an array of germanium detectors enriched to 86% in 76Ge. A background index of 10-3 counts kg-1 a-1 keV-1 in a 10 keV interval around the expected peak at 2039 keV is envisaged. To achieve this a thorough material screening is mandatory in order to select the most radiopure materials. The results of a systematic study of radioactive trace impurities in a selected range of materials using ultra low-level gamma-ray spectrometry in several laboratories are reported.
