Hello

Hi for those who know of the yahoo groups that were run by George Dowell aka Geo or K0FF- I am Daniel and for Last decade plus I have been using CZT and Sodium Iodide detectors.
Unhappy with my confidence in the potential miss identification of isotopes, drift and confidence of results of gamma scintillation MCA's I have built my own software running sound gamma spec and USB Kromek RA4S CZT. 
About 1000 man hours and 20,000 lines of code. 

So hello

Hi, Daniel, and welcome!  Your dedication to accuracy is impressive.  Has your setup shown any surprising events?  Like post-solar storm changes?

Hi Bert, not that I have been looking for, I do however have a huge plastic scintillation block I have experimented with,an interesting project.
Perhaps one to add to bucket list
Current project is PT100 ESP32 temp sensor for Gamma spectroscopy temperature compensation. Runs a full Web interface with WiFi and serial temperature feed.
