Description
In many liquid xenon experiments the radioactive noble gas radon is
an important background source. It emanates continuously from the
detector materials and can reach the sensitive detection region. The
successive decays of its daughter isotopes can mimic the signals
from dark matter interactions. This talk focuses on measurement
methods to determine the radon level before detector assembling,
allowing a careful material selection. A few selected results will
be shown. Furthermore, radon removal techniques will be presented to
achieve a further background reduction.
