Kookie came back yesterday and we both ate
some of the fish fillets for lunch.
I looked into a meter last week
but anything decent was over $400
I'll google ionization chambers
Geez I should check here more often, lots of replies since I was last here.
Dunno if the 'quote' thing worked coz 'preview' doesn't seem to work
Anyhow, good that you & kookie enjoyed some imported fish :-)
Yes most radiation detectors are expensive since the Fukushima disaster, Geiger tubes have become ridiculously expensive...even the "post cold war" Russian surplus.
Which is why ionization chambers are a great alternative. They are used in many data collectors around the Fukushima site to report current radiation levels. (avail online)
I've recently "downgraded" to Windows 10 so all my media is all over the place ATM. I'll post some very simple schematics & pics for an ionization radiation detector in the tech section here when I find it all. 2 darlington transistors, (or 2 PNP/NPN pairs) a few resistors, a panel meter and of coarse a cat/dog food or baked beans can for the chamber. :-)
It wont be as accurate as a "Gamma Scout" Geiger counter but also doesn't have the $500 price tag...a few $'s in parts is all it takes.
