Apparatus and method of measuring effective porosity using radon

摘要

The present invention relates to an apparatus and method of measuring effective porosity of various media such as rock or soil using radon that is an inert gas. An apparatus of measuring porosity according to the present invention includes: a gas component detector having two ports and configured to measure a concentration of a predetermined gas; a gas vessel having two ports and configured to accommodate the predetermined gas; a medium vessel having two ports and configured to accommodate a medium, of which the porosity is desirous to be measured; pipe lines connecting the ports of the gas component detector, the gas vessel and the medium vessel; and valves installed on the pipe lines.
