Descripción
Due to its optical and electrical properties polytetrafluoroethylene (PTFE) is an important construction material for many rare event searches. The radioactive contamination of PTFE thus needs to be as low as possible. We present a cross-sectional study investigating the radioactive contamination of PTFE samples from major European suppliers of raw PTFE. The bulk contaminations of the samples were measured utilizing ICP-MS and HPGe gamma spectrometry; the radon surface emanation was assessed with an electrostatic radon detector that was recently commissioned in Freiburg.
