Abstract:
    The invention is related to instrument for monitoring pollution on surface of tritium in order to solve issues of high cost of device, low efficiency of detection, and poor anti-interference. The invention includes detector, module of signal acquisition, and CPU. Detector is proportional counter in flowing gas type. The counter is composed of cathode of metal covering, as well as anode in wire or piece in inner cavity. Being connected to the output of high voltage module, anode through signal line is connected to the input of the module of signal acquisition. There are gas inlet orifice and gas outlet orifice in the inner cavity. In time of operation, methane gas enters into the inner cavity through the gas inlet orifice, and outflows through the gas outlet orifice continually.
