IONIZATION CHAMBER FOR MEASURING CONCENTRATION OF RADON GAS AND RADON CONCENTRATION MEASURING APPARATUS WITH IT

摘要

The present invention relates to a radon measuring apparatus and a radon measuring method. The radon measuring apparatus measures the concentration of radon gas in the air in real time. The radon measuring apparatus includes a radon detector which is electrically connected to an ionization chamber. The ionization chamber includes a transposition amplifier and is electrically connected to the radon detector through a parallel input resistor which is grounded. The ionization chamber includes multiple electrode plates that are installed to be separated at predetermined intervals in a case. The electrode plates are provided in a plate shape, and are fixed and installed on both sides on the inside of the case by an insulator. The electrode plates include one sensing electrode and two power supply electrodes. The sensing electrode is connected to the transposition amplifier, and the power supply electrodes are connected to a power supply unit and receive power. According to the invention, the ionization chamber can be provided in various volumes and forms by using the insulator for fixing the electrode plates, minimization and operation are easy, and manufacturing costs can be low.
