Cs-137 x-ray energy
WebExpert Answer. Transcribed image text: 10) The following energy spectrum of Cs-137 is recorded with a gamma detector. Find out the energies of: a. (3 pts) Photopeak b. (3 pts) Compton edge c. (2 pts) Backscatter peak d. (2 pts) X-ray peak (note: limited energy resolution of the detector might not allow distinction of individual Ka lines.) 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.

WebNational Center for Biotechnology Information Caesium-137 has a half-life of about 30.05 years. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m ( Ba, Ba-137m). The remainder directly populates the ground state of Ba, which is stable. Barium-137m has a half-life of about 153 seconds, and is responsible for all of the gamma ray emissions in samples of Cs. Barium-137m decays to the groun…
