Abstract

This article describes a radon emanation measurement technique using liquid scintillator counting. A model for radon loading and transport is described, along with its calibration. Detector background and blank have been studied and quantified. The Minimal detectable activity has been determined for the counting setup using a toy Monte Carlo simulation. The measurement technique is validated using a butyl rubber sample previously used for cross-calibration between different radon counting facilities.
