<P>PROBLEM TO BE SOLVED: To provide a radiation monitor device with improved noise resistance, reliability and maintainability. <P>SOLUTION: A waveform analyzer 4 eliminates a noise waveform and outputs a digital pulse corresponding to a signal waveform. A counter 5 counts the digital pulse, and a calculator 6 calculates a counting ratio based on a counted value so as to improve noise resistance. The calculator 6 constantly updates a waveform data package stored in memory 7. A display 8 displays a signal counting ratio and a high-signal-counting ratio alarm when a high-signal-counting ratio is issued. <P>COPYRIGHT: (C)2012,JPO&INPIT |
