Abstract
We report the observation of the trapping of radioactive inert gas rad on (Rn-222) on oxide glass under ambient air temperature and pressure of 300 K and 760 Torr, respectively. Radon diffuses from the source, t hrough two macroporous scintillating-glass-fiber bundle alpha detector s in series, to the end of the linear closed system filled with ambien t air. The strategy is to provide radon atoms and alphas emitted from radon and its progeny with large accessible scintillating glass surfac e areas for efficient trapping and detection, respectively. Diffusion- only transport mechanism could not explain the experimental observatio ns, strongly suggesting the trapping of radioactive inert gas radon (R n-222) on oxide glass.
