The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample. Gamma-ray characteristics Gamma rays are the highest-energy form of electromagnetic radiation, being physically the same all other

The gamma radiation spectrum was analyzed to determine the concentrations of specific radionuclides (40K, 228Ra, 226Ra,238U and 232Th) in Bq/L. Chemical analyses were performed at the Hydroche-mistry Lab of the University of Belgrade Faculty of Mi-ning and Geology to define hydrogeochemical condi-tions and determine groundwater types. The following

Radium-226 concentrations in garden soil in Port Hope, Ontario, Canada contaminated with radium were as high as 830 pCi/g; radium-226 concentrations in soil from plot uncontaminated by adjacent uranium mines ranged from 1.2-2.6 pCi/g (2). 2011-02-04 2021-04-12 The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks. Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seeingt part of the spectrum. The following spectrum was recorded with a 3" NaI(Tl) detector with GS-1100-PRO and PRA 16.
