A word of advice for wannabee stalkers: geiger counters need to be frequently recalibrated, and this can only be done by a skilled person. Unless you bought an expensive one recently, it's probably poorly calibrated already. This explains why all those UFO and ghost hunters keep finding "radiation" everywhere: they just don't understand how a geiger counter works.
Well, if you're near Tchornobyl, even a poorly calibrated one should pick radiation at some point; but then, it may be too late already.
