Run 6973
The following lines were observed by the HpGe detector.
387, 583, 609, 1273, 1456, 1591, 2103
Place a cut around the 511 keV photons seen in the NaI detector yields the following lines observed by the HpGe detector as shown below.
(386, 438, 491, 511, 582, 950, 1255, 1273, 1591, 2103 keV)
Place a cut around the 2103 keV photons seen in the NaI detector yields a 511 and a 583 keV line observed by the HpGe detector as shown below.
A line at 388 keV
- Possible Isotopes
- U-235 (388 - 142,64.5)
- Cf-249 (many coincidence lines)
A clear 511 line
- NaI cut on 2100 keV intensifies 511 keV line,

A line at 609 keV
- Possible isotopes
- Pa-231
A line at 1273 keV
A line at 1593 keV
A line at 2105 keV
