George if I did my math correctly that 168.3GBq is about 4.54 curies of radioactivity. I'm not surprised that the alarm went off with that much radiation in...
Has anyone tried one of the TINY Russian GM Tubes that have appeared on e-bay? I was thinking that it might make for some fun projects - i.e., pocket meter,...

any idea HOW sensitive, that is CPM per 1 mR/H of Cs-137 compared to some other well known probes? Is the op. voltage 400 or some other? Geo ... From: Helmut...
E-bay item number 160025237455 These are SBM21 - 21x5 mm - working voltage of 350-475. "Range of measurement is from 40 microrotengen to 400 microrotengen per...

Also check number 160017670307 12x110 mm, other specs same. I wonder if this one could be directly retrofitted into the 700 with a couple of spacers? ... From:...
We just returned from a trip through Georgia's tobacco country. Noticed that the background radiation there is 4 to 5 times higher than here in the midwest....
I'm looking at tinkering with a Victoreen CD V-700, Ok I'm actually looking buying one, stripping it, and making a totally new board using the lENI Pro circuit...
It can be done, but you have to redesign the switching as the range switch is part of the circuit and is different for each manufacturer. See my 'Mini LENi"...
Like George said, Chris. Notice that the (CD V-700) meter scale is nonlinear, to compensate for the nonlinear properties of the Pulse Rate to Current meter ...
Hello, I have a little question. When I do the HV regulation, with the A meter in battery can, I get around 33mA (but measuring with A! O_o), then my tube wont...

Check the fuse in the meter. The lower current ranges are often fused for meter protection. The higher range current shunt can't be fused, but can stand...

FWIW- I don't know about Polonium, but I read a few years back that phosphate fertilizers are often used in growing tobacco. Isn't K40 an alpha emitter? I...
