These are Radiation Levels, detected outside the Gate at Marshall Steam Station in Sherrills Ford, North Carolina. Marshall Steam Station is a power company on Lake Norman and is a prime source for coal ash that has been distributed throughout the region, as fill dirt in construction and landscaping sites for many years. There is evidence of trucks hauling Coal Ash outside the Gates on these roads, so we test the radiation levels of the ground outside the gate to see if levels are elevated due to spillage or use in constructing the roads or landscape. There are no pin-pointed Hot Spots leading to exposure yet, however the overall readings are above normal, ranging from 11µR/h to 17.4µR/h.
The Gamma Radiation Level Tracks are created with ‘RadiaCode 103’ detection devices. Each colored dot represents a Radiation detection(dose rate), in microroentgens per hour. We use these detections to pinpoint Hot Spots, where Coal Ash is closer to the surface, within Coal Ash Fill Sites. Click on each dot to see the level detected. Radiation Levels range from Purple(Lowest per Track), then Blue, Green, Yellow, Orange and Red(Highest per Track). On each Map you can deselect the Layers (Individual Tracks) to more easily see the Highest and Lowest detection points of each Track.
