Abstract
Radon is removed from a gas in an apparatus having: (a) a liquid-gas contacting apparatus containing a fresh working liquid in which radon is soluble; (b) a shielded reservoir containing the working liquid; and (c) a means for causing a stream of gas containing radon to pass through the liquid-gas contacting apparatus. When the radon level in the working liquid reaches a certain level, the working liquid is either taken out of service and stored until the radon level is reduced or the working liquid is diluted with additional working liquid having no radon.
Claims4
An apparatus for removing radon from a gas in a confined space, the apparatus comprising:
- (a) a liquid-gas contacting enclosure containing a hydrocarbon oil working liquid in which radon is soluble, the working liquid remaining within the enclosure and having no communication with any enclosure that treats the working liquid, the enclosure having an inlet communicating with the confined space, an outlet communicating with the confined space, and walls shielded with a material selected from lead, concrete, brick, sand, water, or soil;
- and
- (b) a means for causing a stream of gas containing radon from the confined space to pass through the inlet and through the working liquid in the enclosure to treat the gas by removing at least a portion of the radon from the gas and then to return the treated gas to the confined space through the outlet.
A structure comprising:
- (a) a confined space filled with a gas containing radon;
- (b) a liquid-gas contacting enclosure containing a hydrocarbon oil working liquid in which radon is soluble, the working liquid remaining within the enclosure and having no communication with any enclosure that treats the working liquid, the enclosure having an inlet communicating with the confined space, an outlet communicating with the confined space, and walls shielded with a material selected from lead, concrete, brick, sand, water, or soil;
- and
- (c) a means for causing a stream of gas from the confined space to pass through the inlet and through the working liquid in the enclosure to treat the gas by removing at least a portion of the radon from the gas and then to return the treated gas to the confined space through the outlet.
