A geiger check-source is a precisely measuredstimulus, used for assessing the measurement accuracy of one's geiger counter instrument. If your geiger probe is a standard pancakeprobe, then it is expected that your measurementof this rock should be within 10% of the valuestated in this ad. If your measurement differsfrom the stated CPM value by more than 10%,then the geiger should be recalibrated.
