OT: Gieger Counters and such

Looks like a crap fake meter.

This meter is also crap. Only reads high levels of radiation that you would be unlikely to encounter. What you need is CDV-700, a very sensitive meter that reacts even to normal background radiation. It also has an alpha detector IIRC. I have one and it is a very fun meter to own.

I think it may only be new tech: pancake tube. Googlit.

Right, the text says it's only good for medium to high levels.

Those go for $174 right now.

Keep it around. It may be handy some day soon if the imported militants or homegrown radicals decide to nuke the USA.

Might have a solid state detector.

At those radiation levels it only predicts life expectancy in days.

Wow i got mine for $10.00 many years ago, still works. A great cold war artifact.

No alpha detector on that model, just a beta and gamma detector.

And a pocket model back in the mid 1950s (the "El Dorado" from Sears) went for something like $30.00 or so. It was a very simple one, with a pushbutton to operate a vibrator which also had a high-voltage winding. This charged a capacitor to a voltage regulated by the Geiger tube itself. Detection did not show on a meter -- just as clicks in an earphone. It was about the size of a pack of cigarettes.

Less than that at hamfests. I forget whether I paid $15.00 or $25.00 for one some time ago.

Perhaps for checking RF leakage through the door of a microwave oven? Certainly does not look like a Geiger counter or any similar device. :-)

Yep -- certainly not for radioactivity. :-)

Ouch!

Enjoy, DoN.
