WebFeb 23, 2024 · 8000 to 16000 spectrum channels is a must; pole zero (PZ) cancellation must be well adjusted on the shaping preamp to eliminate baseline drift; longer shaping time (e.g. 6 to 12 us) might be necessary. The captured Cs-137 and Ba-133 spectra are shown on Fig. 4 and 5. WebSpectroscopic Characterization of the Cs-137 Energy Spectrum. Summary of Research: Cesium is often used in the calibration of radiation surveying tools and thermoluminescent dosimeters (TLDs). This study explores the photon energy spectrum for the cal lab’s Cesium-137 irradiator using a combination of Monte Carlo and spectroscopic techniques.
