People often ask how I got mud. This one I got from a , "Hey Joan!" when I crossed the street after a trip to the post office. Chris Griner gave me sediment from a cruise of R/V Tansei Maru that was monitoring radiation in sediment off Japan. He assured me that the mud wasn't “hot”.

Best to learn more by Googling radiation chemist Ken Buesseler. He came to speak with me about commissioning some bowls and he had his Geiger counting gizmo with him -- It attached to his Iphone and we went through my closets of materials testing things--that reassured me.
Good writing to give you a sense of the place....
Ken Kostel wrote for “Oceanus” :
“The undersea fault that ruptured on March 11 extends north-south about 500 miles, roughly parallel to the northeast coast of Japan. It is a mega-thrust fault in the Japan Trench, where the massive Pacific Plate pushes westward, and beneath, the continental Eurasian Plate. Where the two tectonic plates grind against one another, gargantuan stress builds over time in the seafloor crust. Hundreds of large and small earthquakes dot the fault each year as stress exceeds the breaking point of rocks and releases.”
