Spectrum with iMetry

Electrodes-spectrum.PNG
When compared with the reference spectrum peaks of Thorium series, the spectrum with iMetry might
be a bit out of calibration in general, but still
  • 583keV seems to be detected
  • The peak on the right of 583keV might be combined peak of 911, 964, and 968Kev.
  • Slight raise on the right can be seen, this may be 1588 and 1630keV, longer measurement may give clearer spectrum.
  • On top of the raise on the very left of the graph, there seems to be some dent. This might be the gap between 238keV and 334keV.
