How to read this decay sheet (gamma emission after beta decay)

[dRic2]

TL;DR

I would be very grateful if someone could help me reading this decay scheme

I was looking at the decay scheme (https://www-nds.iaea.org/relnsd/vcharthtml/VChartHTML.html) of $^{112}Ag$ which $\beta$-decays to $^{112}Cd$. $Cd$ is most likely left in an excited states, so it decays to its ground state by $\gamma$-emission. As you can see there are tons of possible energy levels, so there are tons of possible gammas. If I were to measure those gammas with a scintillator (with not very high energy resolution) which one would give me an observable peak ? I can't figure this out...

For example, take the first one (in the gamma-table): I have a gamme of energy $120keV$ emitted by the transition from the level with energy $1433keV$ to the on with energy $1312keV$; it says $I_{\gamma}(abs) = 0.076 \space 12$ but what is it ? Would it be detectable ?

Thanks in advance.

It says 617.517 keV and 42% under "major radiations". That's what you should look for.

Sorry, but where did you find "major radiations"? Anyway, the 617.517 keV gamma is the one with the highest $I(abs)$ which is exactly 42. So I just have to look for the highest value of $I(abs)$ ? (I'm referring to this table)

Hover over the nuclide.
