REAL TIME AND AUTOMATIC RADON MONITORING SYSTEM WITH DIRECT CONNECTER USING GROUND WATER BORE HOLE

摘要

PURPOSE: A system for monitoring radon in real time with direct delivering method using subsurface water bore hole is provided to precisely measure radon included in subsurface water or soil without any disturbance and restriction from external environment and prevent frost formation inside a sealed container which occurs due to temperature difference. CONSTITUTION: A rubber packer(21) is formed inside a bore hole(11) and closely adhered to the inner circumference of the bore hole by being expanding with the injection of air. A radon collecting pipe(22) passes through the upper and lower of the rubber packer and collects air in the bottom side of the bore hole which is tightly shut with the rubber packer. A dehumidifier(30) is directly connected to the radon collecting pipe and eliminates moisture in the air which flows in through the radon collecting pipe. A radon collecting apparatus(50) includes a pump(40) which is directly connected to the dehumidifier and forcibly absorbs the air in the bottom side of the bore hole.
