The physical properties of cobalt such as resistance to bulk oxidation and low solubility in water give some advantages in safety in the case of a containment breach over some other gamma sources such as caesium-137 . The ..gamma..-ray energies, in the range E/sub ..gamma../ = 60 to 6100 keV, are all based on the value of 411 804.4 +- 1.1 eV for the ..gamma.. ray from the decay of /sup 198/Au. The energy of the 6129-keV line in /sup 16/O, which is the ..gamma.. ray with the highest energy more » of the present set, was also measured relative to another standard; the two values are consistent.

Eu152 Gamma Spectrum Europium 152 and Europium 154 This excellent spectrum was kindly provided by Christoph Denk, an uncommon isotope to get hold of, Eu152 and Eu154 is a man made isotope, and has a half life of 13.5 years. This Spectrum was recorded with GS-1100A and a Harshaw Scintillation Detector.

Gamma-ray astronomy is the astronomical observation of gamma rays, the most energetic form of electromagnetic radiation, with photon energies above 100 keV.Radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy.. In most known cases, gamma rays from solar flares and Earth's atmosphere are generated in the MeV range, but it is now known that gamma rays in the GeV
