Measuring Radioactivity

We no longer sell Geiger Counters, but here is an interesting article. It's about the various systems of measuring radioactivity and how to convert CPS (Counts Per Second) to Sieverts (a measure of 'risk' to human tissue). It's just so rare to find these explanations that I've decided to keep it on this website for all to see; however, PLEASE do not contact us about Geiger Counters or about radioactivity, we are no longer inovolved in this field.
