Redlands, California
One of the members of my Glowing Conversations radiation group posted the results of some manure he bought from the hardware store for a home garden. Luckily he measured the manure first with his Geiger counter. Normally, this meter is only 25 CPM or so when measuring background radiation. As you can see from the video, the 10 minute average is 240 CPM or 247.5 CPM or about 10x an assumed background level of 25 CPM.
