Description
A novel system for ultra-sensitive Radon emanation studies has been developed. It is based on a cryogenic
Radon detector coupled to two large-volume chambers, able to accommodate samples up to 250 L in volume. Due to the unique properties of the detector it is possible, for the first time, to study simultaneously emanation of two Radon isotopes, namely 222Rn and the short-lived 220Rn. Special design of the system results in an extremely low internal background, making detection of even single atoms of Radon possible. The design and performance of the detector system will be discussed and results of 222Rn and 220Rn emanation for various samples will be presented.
