An accurate do-it-yourself radiation meter

What I don't get is the 2 orders of magnitude difference in capture area.
Sure, ANY PN device can in someway be a radiation detector, but the Geiger
tube has a hundred times more capture volume than most any PN device.
So as far as giving an idea of background radiation, I cannot see these
point source detectors as much more than a curiosity. Or I am missing
something. I think the best detector is a LCD display with background
plazma lighting. Bias the lighting electrodes just below threshold and then
any event anywhere in the 1/2 square foot area should be detectible?
