West Yellowstone station upgrade:

I've deployed a spectrum analyzer at the West Yellowstone site to perform detection and filter-based spectral analysis for radioisotopes from Radon and Thoron decay (natural uranium progenies). This will allow us to more accurately determine any influence on our survey data from the Ludlum and Thermo-Scientific instruments currently used there.

Thank you to station operator "Emerald Eye" for piquing my interest in this additional study.

For instrument information and method see the added station information for West Yellowstone in the first post of this thread.

I will be updating the top post with daily measurements from this instrument.
