Ordered some metal sample packs to test other than foil. Tested the C110 copper sheet pack today, approximate 4x4 x .016, .021, .032, .04 and.0625inches. Recorded the data and didn't see 5 decay lines. Received (2).021, (2).04 and (1).0625 plate. Recorded the 5 plates stacked also. Plates have a .05mm plastic film covering them so not touching. Didn't know if %IACS would be close to 100. I have a 99.9% copper coin that calculates %IACS<100 with .06 multiplier and Carl had less than 100 with his test of 99.9% copper, reply#253 nugget simulation thread. Calculated TC assuming 100% and with multiplier .065, looks like .065 is to high or some other problem.
Have a Brass260 and 6061 aluminum pack to test yet. Some .0007inch(.0178mm) and.00135inch(.0343mm)C110 copper foil coming to test. Not sure what will learn with the brass and aluminum packs, multiplier and %IACS?
