  1. Think you for bringing this G-M technology to a lange portion of the masses with low cost hardware. In thin vein do you supply Linux based, open source software to compliment your instrument line?
    Also. until relatively recently scintillation caliber survey & lab meters were based on expensive sodium iodide crystals. When will you be offering such instrumentation based on much lower cost polymer based detectors?

    • Hi Greg,

      We only provide the Windows version right now. In development with an iOS version though. As for the plastic scintillators, we haven’t had a product that would incorporate them.
