WebNonthermal food processing technologies, such as X-ray and electron-beam irradiation, ... Gamma radiation is generated by photons emitted from radioactive isotopes such as cobalt-60 and cesium-137. Even though the energy range of these photons is narrow — 1.17 mega-electronvolt (MeV) to 1.33 MeV — these photons have no mass and therefore ... 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. philosophy renewed razor sharp
