Suplemental data for material radiopurity control in the XENONnT experiment

The selection of low-radioactive construction materials is of the utmost importance for rare-event searches and thus critical to the XENONnT experiment. Results of an extensive radioassay program are reported, in which material samples have been screened with gamma-ray spectroscopy and mass spectrometry. Several live years of data, aggregated across all instruments, were acquired throughout the radioassay program of XENONnT. Relevant measurements for detector construction are covered in the manuscript '<strong>Material radiopurity control in the XENONnT experiment</strong>' (<em>arxiv:2112.05629v1</em>) . Supplemental data is available in here. <strong>NOTE:</strong> Current screening results are only preliminary, and contain a small set of the overall screened dataset.
