170067	Soil + Se (0.05%)
170068	Ash + Se (0.04%, Oven Method)

Using Detector D at the IAC, I had to get a count on the unirradiated soil sample that was collected. Here are the GPS coordinates ****

Here is the spectrum produced:

The details of the calibration along with the constants found from a linear fit of temperature vs. voltage can be found in the page below.
