Abstract
Two macroporous fiber bundle radon sensors were developed by close-packing the 50 μm fibers drawn from scintillating oxide glass in the quartz tubes. Radon (222Rn) diffuses from the source, through these sensors in parallel or in series, to the end of the linear closed system filled with air under ambient temperature and pressure of 290.15 K ∼ 307.95 K and 760 Torr, respectively. The strategy is to provide radon atoms and alphas emitted from radon and its progeny with large accessible scintillating glass surface areas for efficient trapping and detection, respectively. The variations of count rates over 115 days indicate both the significant trapping of radon on the glass surfaces as well as the dependence of this trapping process on temperature.
