Hi, i've taken a 2000s spectra with a 3"x3" Luuk detector and an improvised 2cm lead shield made with 2mm lead foil wrapped around detector.

Hi Luuk,
it appears only with lead foil wrapped around as shielding, so i think it is a lead xrf for sure, maybe splitted Ka-Kb lines?? Really i don't know what else could be this peak!
It's showed also in Theremino during Cs137 calibration ,i can send you the pic off list not hijacking this 3d.
