Abstract:

 

In this study, the gamma-ray energy spectrum of 137Cs radioactive source was obtained as high resolution using digital signal processing system. Obtained analog signals from radiation source were collected converting to digital signal via established computer aided measurement system which both 14-bit resolution and 100MS/s real time sampling rate. The high resolution spectroscopy of 137Cs radiation source were improved by LabviewTM algorithms. Since the PCI 5122 card has two channels, uncalibrated scintillation detector is compared with precisely known correctness of calibrated scintillation detector. This calibration process helps to find the deviation of the indications relating to uncalibrated scintillation detector with regard to true value of calibrated scintillation detector.

 


SAYISAL SİNYAL İŞLEME SİSTEMİ İLE YÜKSEK ÇÖZÜNÜRLÜKLÜ RADYASYON SPEKTROSKOPİSİNİN ELDE EDİLMESİ VE KALİBRASYONU

Bu çalışmada, 137Cs radyoaktif kaynağının gama ışın enerji spektrumu, sayısal sinyal işleme sistemi ile yüksek çözünürlüklü olarak elde edilmiştir. Kurulan bilgisayar destekli ölçüm sistemiyle, radyasyon kaynaklarından alınan analog sinyal, 14 bit çözünürlükte, 100MS/s gerçek zamanlı sayısal sinyale dönüştürülerek toplanmıştır. 137Cs radyasyon kaynağının yüksek çözünürlüklü spektroskopisi, yazılan LabviewTM tabanlı DSP algoritmalar ile geliştirilmiştir. PCI 5122 sayısallaştırıcı kart iki giriş kanalına sahip olduğu için, kalibrasyonsuz sintilasyon detektörü, doğruluğu bilinen kalibrasyonlu sintilasyon detektörü ile karşılaştırılmıştır. Bu kalibrasyon işlemi, kalibrasyonlu sintilasyon detektörünün doğru değerlerine göre kalibrasyonsuz sintilasyon detektörün gösterge değerleri arasındaki sapmayı bulmaya yardım eder.
