WebApr 3, 2024 · Our results show that the X-RAD 320 photon energy spectrum was suitable for ablating bone marrow at the 3 exposure levels used, similar to that of 137 Cs photons. However, the 320-kV X-rays were not as effective as the much higher energy γ rays at depleting mouse splenocytes. Furthermore, the 3 X-ray levels used were less effective … 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.
