る放射線監視装置。 A radiation detection unit that detects radiation and outputs a detection signal according to the result, and a radiation detection unit that constantly outputs a threshold signal and, when a threshold setting signal is input, detects the threshold value represented by the threshold signal. threshold signal generating means for updating the threshold value to a value according to the threshold setting signal, the detection signal and the threshold signal are input, and the threshold signal represents the waveform of the detection signal. a discriminator which discriminates the wave height using the threshold value and outputs a pulse train signal according to the result; and a discriminator which receives the pulse train signal and counts the number of pulses in the pulse train signal for a predetermined counting time. a pulse calculating means that repeats the operation of outputting a counting rate signal according to the count value per unit time of the counting result; a first alarm setting value signal generating means for updating a first alarm setting value represented by the first alarm setting value signal to a value corresponding to the alarm setting value setting signal; and outputs a first alarm signal when the counting rate represented by the counting rate signal exceeds the first alarm setting value represented by the first alarm setting value signal by performing a comparison operation on both input signals. 1 comparison means, an output signal of the first comparison means including the first alarm signal and the alarm setting value setting signal are inputted, and the alarm setting value setting signal is inputted successively within a predetermined waiting time. then, the output signal of the first comparing means is blocked from passing, and when the input time interval of the alarm setting value setting signal inputted subsequently exceeds the waiting time, the output signal of the first comparing means is passed. a plurality of radiation measurement units, each of which is provided corresponding to each of the radiation measurement units, and which constantly outputs a second alarm setting value signal and into which the alarm setting value setting signal is input; and a second alarm setting value signal generating means for updating the second alarm setting value represented by the second alarm setting value signal to a value corresponding to the alarm setting value setting signal, and a second alarm setting value signal generating means corresponding to each of the radiation measuring section. the count rate signal and the second alarm set value signal are input, and a comparison operation is performed on both of these input signals so that the count rate represented by the count rate signal is determined as the second alarm set value signal. a second comparing means that outputs a second alarm signal when the second alarm setting value represented by is exceeded; and outputting the threshold setting signal and the alarm setting value setting signal to all of the radiation measurement units. and a control section for outputting the alarm setting value setting signal to all of the second alarm setting value signal generating means; a signal processing section provided corresponding to each of the radiation measuring sections; The gate means outputs the first
the alarm signal and the second output from the second comparing means;
an alarm device that performs an alarm operation when at least one of the alarm signal and the alarm signal is input; and the control section periodically outputs both the alarm set value setting signal and the threshold setting signal. A radiation monitoring device featuring:
