WebThe half life of cesium-137 was determined to be 29.2 plus or minus 0.3 years by an all mass spectrometric method. The abundance of the 662 Kev gamma- ray in the decay scheme was found to be 0.82 plus or minus 0.03 per beta disintegration. In the course of the work, the isotopic distribution of natural barium was determined with improved ... 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 …

Spectrum of a fruit from Bikini Island with a high concentration of 137 Cs (Left) and spectrum of a fruit from Utirik Island, with a low concentration of 137 Cs (Right). WebCaesium-137 is one such radionuclide. It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable.
