Hi,

I was doing a measurement on a Cs-137 source, strong enough so that my detector registers a sum peak.

I cant get my head around A, the peak at ~80 keV.. I get B (backscatter peak), C(compton edge) and D total abs.peak.

I tried with a weaker Cs-137 and I saw the 35keV (Ba) but no ~80keV.

Any ideas?

Thank you very much!

Is your more intense Cs source contained in a lead pig?

Yes it is.

What are you suggesting my friend?

Gamma spectroscopy regarding Cs-137


Wow.... I Feel real stupid now.
Its the X-ray from lead (K-shell) that is 88keV.

Thank you very much!

I knew you could figure it out with a hint!
