Collection and behaviour of radon progenies on thin Mylar foils
Thin Mylar foils are often used to protect detectors from contamination. However, these foils can be
electrostatically charged, possibly leading to their contamination with airborne radon progenies. In the
present work, the collection and behaviour of radon progenies on Mylar foils was investigated in detail
using alpha spectrometry. The radon progenies collection rate of a small Mylar foil (3 cm2) is equivalent
to an air sampler with a flow rate of approximately 0.1 m3/h. It was demonstrated that such contamination
may jeopardise the validity of the entire analysis if not interpreted correctly.
