It is very neat for the price - the spectral resolution from Cesium Iodide is less than Sodium Iodide by more than half and it's a small crystal .. but it does pack a lot of fun into a small package.

If you're in the earth sciences, I linked a data sheet for the crystal: https://www.gammadata.se/assets/Uploads/CsITl-and-Na-data-sh...

There's a reddit community: https://old.reddit.com/r/Radiacode/

and a desktop interface: https://downloads.radiacode.com/EN/RC-101_Windows.pdf

with a few OS choices.

For semi serious use I'd want to continuously download full spectra with a (?) 2 to five second window (subject to understanding how well it counts, subsamples, saturates) and pool those spectra with GPS data to build up NASVD type "typical background" fingerprints to differentiate against to boost outlying signals.

I'd like to see the gadget user groups pooling their data also.

First thoughts on browsing the manual is that spectra export is a UI interface driven one at a time operation so someone would want to get into the guts of that and determine how to continuosly transfer to a server | home PC | nearby phone to retransmit, etc.

This, of course, might be in the reddit forum or Telegram group.

I might get a few of these as Xmas presents for a few folk I know that work with the bigger geophysical survey toys to get some cross over happening.
