ABSTRACT:
An apparatus utilizing an activated charcoal collector and a forced air system to provide a sufficient quantity of air to saturate the collector within a significantly short period of time. Mechanically dried activated charcoal particles are exposed to ambient air in order to saturate the particles with radon gas. Radon gas particles adhere to the surfaces of the activated charcoal particles through the action of Van der Waals forces. The charcoal particles are subsequently analyzed in a photospectrometer to determine the rate of discharge of radon decay by-products (progeny) emanating from the charcoal. The apparatus of the present invention, through utilization of a forced air system, reduces the charcoal-saturation exposure time to a small fraction of the exposure time necessary for prior mesurement techniques.
