Gamma Spectrometry Forum

I am just starting out and seem to have questions mostly about fundamental things.

I just got one of Steven's 2" NaI(Tl) detectors and a GS-PRO-V5. I am learning to use the PRA SW.

Is there any SW I can use to label the peaks that are found in the histogram? I started out with a Radiacode 101 and the SW that comes with it for a PC shows what the name of the isotope is when the mouse is over its peak. Do any of the currently available programs have a similar feature?

Is the source code for the PRA SW available to look at? I have a real-time microprocessor programmer background and would like to have a look with adding this feature in mind. I may be in over my head but I would like to investigate this. No promises. GUI interfaces are not my forte..

Thanks,
Mike D.

Mike,

Not aware of any SW that allows the user to label peaks, but some like Theremino and Becqmoni have isotope libraries, and I recall seeing some little flags with names.

Impulse is the only open source, so if you know Python you are welcome to create a fork and hack as much as you like.

I re-read my post's questions and I think I wasn't clear. I want some SW to label the peaks for me, not let me label the peaks.

My Radiacode 101 has some nice Russian PC SW that does that. Apparently it does it on the phone version of the SW too, but I don't have that. I am inserting a screen shot of it looking at a quick spectrum from the RadiaCode 101 on a Spectrum Techniques CS137 disc. I then clicked on the obvious (Even to me! I guess I am starting to learn!) CS137 peak. It shows in the upper left hand title area of the screen the name of the isotope ('Cs-137') that would be responsible for this peak. It seems like it would be a 1 to 1 mapping of the eV to the name. I am thinking that if it were so easy someone else would have added it to some more programs.

Hi Mike,

you can also have a look at my Gamma MCA application if you want something more mobile without downloads: https://github.com/OpenGammaProject/Gamma-MCA (also viewtopic.php?f=7&t=1055)
1:1 mapping of the eV to the isotope name is (very) trivial, it works like that in my program. You need a pretty good calibration because there are so many other isotopes possibly close to the one you're looking for, but most of the time it works fine.

No, that's just wrong, you're not the only one like I just mentioned. Also, the new BecqMoni and the great Theremino MCA are both open source as well and have isotope labeling that works fine.

Thanks for correcting me, yes there are indeed other open source projects now, great for science.. 🙂

Interspec also lets you label the peaks, you even can put an user-label on a peak if you want.
Also you can display reference peaks, for example the thin red lines in my image are "reference peaks" for CS-134

Thanks Jonathan, I was already wondering if Interspec didn't implement a feature like this. But I never really used it, so I can't tell. :)
