SOIL RADON GAS COLLECTING METHOD AND DEVICES

摘要

PURPOSE: A soil radon gas collecting method and a device thereof are provided to improve the efficiency of work. CONSTITUTION: A time integrate type radon concentration measurement device(20) is installed in an installation hole under soil(10). The trajectory of radon emission alpha ray inside soil is recorded in real time with a sensor. A gripper(40) installs the time integrate type radon concentration measurement device into the inside the installation hole or collects it to the outside. A cover(30) includes a closure unit(31) and a support unit(32). A sealed part seals the top opening unit of the installation hole. The support part is projected in the outer circumference of the sealed part.
