White Signal bassetite


 

This is a scan that ran for 1 1/2 days using Am241 to excite.? It has a lot of stuff in it and I will need everybody's help to interpret it (i.e. Dud).? One complicating factor is that even with the Am241 the count rate was quite low.? This causes the Am241 Np peaks (along with Au and Ag) to appear so they have to be sorted out.

Here are my notes in the comment box:

bassetite? White Signal
¹ó±ð2+(±«°¿2)2(±Ê°¿4)2¡¤10±á2°¿

main elements identified:
Fe Pb Rb Y Sn Te Cs Ba Ce

RbKa1 could be ULa1&2
YKa1 could be RbKb1
NpLb2 seems too big and could contain YKb1

Sorry I forgot the .mca. I'll send it in a bit.

Charles,

This is pretty messy and really provides not a lot of information due to interferences and low count.

I would suggest you get a piece of known composition steel (SS 316 would be niece) or Aluminum and plastic run a ¡°background count¡± to see where all these repetitive hits you keep getting are coming from ie Au , Rb, Te, Y etc.? Set some ROI¡¯s on those interferences so they show ?up on subsequent samples. ?

Well, we know that the Au is coming from Am241 source.
