How does one change the channels used in a Region of Interest (ROI)?
I’m looking for natural radioisotopes and the detector (H100) produced a very nice Bi-214 peak at 609 KeV. Although the “Natural” custom library I created has Bi-214 in it, Visualizer Marks the peak as an Unknown at 608 KeV.
I’d like to adjust the ROI so it is centered better, hoping that Visualizer would then ID the peak correctly. That, or I’d like to manually ID the 609 KeV peak as Bi-214. Btw, I have tried using the “Isotopes near…” method several times, but it doesn’t seem to “take”.
