I obtained a sample of this from eBay user cgroat3573 and it took me some time to figure out the sources for the peaks. The peaks are around 33, 66, 96, 143.8, and 185.7. The 143.8, and 185.7 are from 235-U. In Logarithmic we also see the 766 and 1001 lines of 234m-Pa. Do I assume that the 96 peak i...
It's the blue one at the far left side. I've seen it before but didn't know what it was. So, I put the Americium sample in the castle and let it build up the peaks. Then I replaced the Americium with my Carnotite and watched its familiar peaks build. Then I used the known 59.5 and 609 peaks for cali...
I wasn't seeing much on the higher end energies at 700v so I moved it up to 850v where I know where 59.5 is located on the scale. I found this to be quite a surprise! ROI from left to right - 63 & 93 from 234-Th, 186 from 226-Ra, 569 from 207-Bi (or 583 from 208-Th?), and 1001 from 234-Pa. Maybe one...
