Abstract
Abstract
Radon and radon daughters pose significant backgrounds to
rare-event searching experiments. Activated carbon, which has very
strong adsorption capacity for radon, can be used for radon removal
and radon enrichment. The internal 226Ra concentration
ultimately limits its radon enrichment ability. In order to measure
the intrinsic background and study the radon adsorption capability
of Saratech activated carbon at various temperatures, a
radon-emanation measurement system with a high-sensitivity radon
detector and an adsorption-performance research-system have been
developed. In this paper, a 0.71 mBq/m3 high-sensitivity radon
detector and measurement details of the radon-adsorption capability
of Saratech activated carbon at low temperature will be presented.
