SOIL RADON GAS SAMPLING APPARATUS AND METHODS FOR RADON GEOCHEMICAL EXPLORATION

摘要

PURPOSE: A device and method for collecting soil radon gas for a radon geochemical exploration are provided to accurately measure the content of soil radon by using an indoor air measuring device. CONSTITUTION: A hand auger excavates a measurement hole on an earthquake belt by a soil excavator. A radon collecting device(200) collects radon gas discharged from a soil layer. A locking device(300) locks or unlock the air injected to an air injection tube and radon gas collected through a plastic soil air collecting tube(240). An air suction device manually or automatically suctions radon gas collected by the radon collecting device. A vacuum syringe(500) directly collects and measures radon gas. The indoor air radon measuring device measures the content of the radon gas.
