I just got 20 PIN photodiodes pn# S1223-01 for $1 each from Electronic
Gold Mine, see
http://www.goldmine-elec-products.com/p ... ber=G13585.
These diodes can detect X-ray and Gamma, and if you remove the glass
window, they will detect alpha and beta.
For the Data sheet, See http://sales.hamamatsu.com/index.php?

Google has numerous references to PIN photodiodes as radiation
detectors!
Also see http://www.maxim-ic.com/appnotes.cfm/an_pk/2236
This schematic is from http://sales.hamamatsu.com/assets/applications/

One issue is how much bias voltage to use... Zero, 50 and 100 volts have
all been used in examples using this S1223 photodiode. Has anyone any
informed insight as to the best preamplifier circuits?

Re: $1 solid state radiation detectors
I have heard of banks of these working as a crude detector. But nothing touches the GM tube for alpha-beta or the Scintillator for gamma.
A servicable gamma detector might be cobbled up out of a phalanx of PIN diodes. There are, as you note, a lot of circuits online.
I haven't bothered with them due to not having heard any glowing reports concerning them.
