  • Probing Question: Could your kitchen counters be radioactive?: "Granite, as a rock, is prone to having more radioactive metals in it due to the method by which it forms," explained Poterala, a materials science graduate student. "Typicall y, the uranium and thorium that produce radioactive minerals will crystallize into granite because they don?t crystallize well into other rocks." As a natural source of radiation, granite contains 10 to 20 parts per million of uranium (as opposed to something like limestone, which contains 1 to 5 parts per million of uranium). So yes, there is a good chance your kitchen countertop will be at least minimally radioactive.
