Nice to see the list is back.  I've been making a few variation of Geiger Muller
array detector here is one http://www.hardhack.org.au/geiger_muller_detector I'm
yet to post the ten tube version :-)

I'm also building another unit with PMTs I have the tubes and electronics. But
need some scintillation panels anyone know where I can purchase this from at a
realistic DIY ers cost, don't mind overseas shipping costs.
