Abstract

Abstract A method for collecting radon in a confined area and testing therefor includes the initial step of providing a container with a molecular sieve material for attracting radon and placing the container in a confined area where radon is suspected to be present. The container has an open inlet end, into which radon will be attracted by the molecular sieve material in the container. The container is left in the confined area for a predetermined time, after which the container is removed so as to remove any radon present within the confined area and the molecular sieve is tested for radon.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 209 words
A method of collecting radon in a confined area for the removal and testing thereof, comprising the steps of: providing a container having an open inlet end closed by a removably sealable lid means, said container being filled with a molecular sieve material which has the inherent characteristics of attracting radon, said container having a perforated plate removably mounted in its upper end, the perforations being of a size smaller than said molecular sieve material to prevent removal of the material yet permit the flow of air therethrough, placing the container in the confined area, removing said sealable lid to reveal the open inlet end of said container, waiting a predetermined period of time with the container in the confined area, whereby at least a portion of any radon in said area will be attracted to the molecular sieve material in the container which will substantially remain therein, resealing said lid on said 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 said area, testing the molecular sieve material for radon, and subjecting the molecular sieve material to temperatures high enough to purge the material of radon.
