I've had my eye on this one. Not affiliated, just looks fun. https://www.radiacode.com/

Ok. This is very cool.

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.

Well, for the purposes of observing the Cherenkov light it is fairly important the material is transparent at blue wavelengths :)

To be a bit nit-picky, Cherenkov light typically has a wide spectrum. For water it spans the entire optical range, peaking around 350nm and dying off at longer wavelengths. So you could, for example, put dye in water such that it absorbed more blue light, but you'd still be able to observe some red light from the Cherenkov radiation escaping. But the signal would be much fainter. Although, one further caveat, changin…

Agreed the classical electrodynamic approach lets us derive this relationship in terms of electric fields (Ampere-Maxwell and Gauss given a suitable gauge), a change in permittivity /varepsilon lets us change the region of this effect
