Description
Radon-222 is a limiting background in many leading dark matter and low-energy neutrino experiments. At SNOLAB, we operate several radon assay systems dedicated to material screening and to measuring radon concentrations in N₂ gas systems and ultra-pure water. This talk will describe these instruments and their capabilities. In addition, it will highlight a recent development aimed at improving our N₂ gas assay sensitivity and expanding our radon measurement capabilities
