3. Adjust the coarse and fine gain of the MCA such that the 1408 keV peak is visible in the high-energy region of the spectrum.

These peaks, labeled Full-Energy Peak, Single-Escape Peak, and Double-Escape Peak, will be separated by 0.511 MeV increments. Fig. 7.4 shows a typical spectrum that would be obtained for an incident gamma energy of 2.511 MeV. This is a table of commonly-observed gamma energies, arranged by increasing gamma energy. The parent isotope and its half life are listed with the gamma energy. The key gamma energy for an isotope has an asterisk following it. Each isotope is listed once with its complete set of gamma energies. The gamma decay fraction from Spectrum Techniques, Inc, in Oak Ridge , TN. The experiments as described will work with any NaI(Tl) detector-MCA combination, but the Experi-ment #9 detector efficiencies will be different for other detector sizes.

Standard Capsule Designs. Activity Tolerance ± 15% from nominal. For High Energy Gamma applications requiring a long half-life radionuclide, these sources offer a broad gamma spectrum between 122keV and ~1408keV.
