Abstract:
    A device for detecting radon and its daughter alpha energy spectrum using normal pressure air impulse ionization chamber, which is consists of normal pressure air electron pulse chamber and charge sensitive amplifier, it is characterized by that : the utility model said that normal pressure air electron pulse chamber is a closed chamber, so the measured radon by communicating gas nozzle into a high piezoelectricity shaped 1 cavity, the cavity in vivo has a superior collector electrode 3, whose collection and output signal directly couples between input port (S I N _ I N) of the charge sense amplifier, and then through the charge sensitive amplifier to amplificate and output, output terminals (S I N _ O U T) create the signal that is directtly proportional between amplitude and incoming alpha particle energy, and then attach them to multitrack kicksort instrument, so it can measure radon alpha1 spectrum.
