You'd need to convert the salt to nitric acid to cause serious mayhem. (Same skill level as running a chlorate cell, probably) Appreciate the original article!...

I own a Victoreen CD V-700 6B. This is for hobby use where official calibration/certification is not a concern. My unit appears to be reading high from what I...

Maybe try it without the outer probe housing, just the tube? There is a dither point, but the GM pulse should be way, way above that. Have you compared the HV...

Good idea Jay, but I already did that! It's a thyroid scan collimator, problem is it weighs a lot and has to be mounted on a tripod. No easy way around that...

... Geo, for higher energy gamma (>.5MeV?) would it make sense to use an inline coincidence detector with fixed delay and two sints (or other fast sensor) for...
