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. 2 figures, 2 tables.

If your source is purely Eu-152, then use the relative instensities and the areas of the matching energy peaks to develop an efficiency vs energy graph.

Our gamma spectrometers can identify unknown radioactive elements or nuclear isotopes by their unique gamma energies, especially suitable for quantifying trace elements in food and soil. A good gamma spectrum with our scintillation detectors can measure down to a few hundreds of Becquerel per kg. COMPLETE KITS The Lund/LBNL Nuclear Data Search Version 2.0, February 1999.

Gamma rays have energies typically in the range of 0.1 to 10 MeV and its frequency (f ≈ 1019-1024 Hz). Characteristics of the energies differs between nuclear states and those corresponding wavelengths between 104 and electromagnetic radiations . Consequently, direct measurements of their energies with a magnetic spectrometry are not possible.
