An example of gamma-ray spectrum in 100-600 keV is shown in Figure 1. A few gamma-ray lines were detected and their lines are identified. The Be-7 line is the strongest but the Ra-226 line is weak, as shown in Figure 1. We plotted temporal variations in surface Be-7 and Ra-226 concentra-tions in 2002-2006 in Figure 2 and 3, respectively.

Two radioactive materials were used to prepare the sources for spectrometric measurements and two different spectrometric systems with calibrated HPGe detectors were used. Ra-226 (the 15 other radionuclides on the list were already regulated by the NRC). For these reasons, Ra-226 should be regulated consistently throughout the United States. Although many States in the U.S. had previously regulated Ra-226, the NRC lacked comprehensive authority to regulate radium and provide leadership in this area until the The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks.

This part of neutron’s energy spectrum constitutes most important part of spectrum in thermal reactors. corresponding to the energy of incident gamma-rays of a single energy. This is desired for gamma-ray spectroscopy because we are interested in knowing the energies of the various gamma-rays that are emitted by a source. In Figure 3.3, we see what the ideal photopeak created by mono-energetic gamma-rays of a single energy looks like.
