Title:
放射線出力監視装置
Document Type and Number:
Japanese Patent JP4334256
Kind Code:
B2
Abstract:
To provide a highly reliable radiation output monitor by solving problems in the digital signal processing of output signals from a radiation detector installed in a reactor.
After output signals from an SRNM detector 1 is amplified by a preamplifier 2, they are converted into digital signals by an A/D converter 3. The waveforms of these digital signals are shaped through linear differentiation filter processing in a signal identification component 4. Though bipolar pulses appear in the process, lagging ones of them are selected to discriminate pulse heights. This can prevent miscounting due to the occurrence of undershoot and enables accurate pulse instrumentation.
