  We report results from a systematic measurement campaign conducted to
identify low radioactivity materials for the construction of the EXO-200 double
beta decay experiment. Partial results from this campaign have already been
reported in a 2008 paper by the EXO collaboration. Here we release the
remaining data, collected since 2007, to the public. The data reported were
obtained using a variety of analytic techniques. The measurement sensitivities
are among the best in the field. Construction of the EXO-200 detector has been
concluded, and Phase-I data was taken from 2011 to 2014. The detector's
extremely low background implicitly verifies the measurements and the analysis
assumptions made during construction and reported in this paper.
