Method for collecting radon and testing therefor
This patent describes a method of collecting radon in a confined area for the removal and testing thereof. It comprises providing a container having an open inlet end closed by a removably sealable lid means, the container being filled with a molecular sieve material which has the inherent characteristics of attracting radon, the container having a perforated plate removably mounted in its upper end, the perforation being of a size smaller than the molecular sieve material to prevent removal of the material yet permit the flow of air therethrough, placing the container in the confined area, removing the sealable lid to reveal the open inlet end of the container, watching a predetermined period of time with the container in the confined area, whereby at least a portion of any radon in the area will be attracted to the molecular sieve material in the container which will substantially remain therein, resealing the lid on the container, removing the container from the confined area so that the molecular sieve material may be tested for the presence of radon and so that any radon may be removed from the area, testing the molecular sieve material for radon, and subjecting the molecular sieve material to temperatures high enough to purge the material of radon.
