Weblaboratories have begun the conversion from Cs-137 to x-ray devices, however this process has a number of challenges. Existing low energy x-ray machines might be a good substitute for blood irradiations, however, diverse uses of research irradiators require higher x-ray penetration with good dose uniformity and therefore higher energy. Webaccount radioactive elements with gamma-ray lines near the peak energy of Cs-137 at 662 keV. In regions with higher concentrations of the natural radioactive elements uranium and thorium a peak near 600 keV is found, containing the 609 keV line of Bi-214 and the 585 keV line of Tl-208. Additionally a Cs-134 line is located at 604 keV. dfk heros professionsWebFor these measurements, both 137Cs and 60Co sources were used to determine and confirm the origin of the peak structure shown in Fig. 1.
