[ RadSafe ] Hot particles on automobile air filters

[Emer, Dudley (CONTR)]

Could be Te-132 at 228 keV with 88% and 111.8 + 116.3 keV at 3.8%. Why no Iodine though?
An energy axis would be most helpful.  What were the count times and the sample to count time?

 I think see them. in the spec that prof terry provided via pdf.
 at least the lines  605 with 97% intensity and the 796 with 85 % itensity. 
 I plot a graph and  they are in line with the claimed americium line.
well the other peaks at about 120 and around 240  I do not recognise.
