Figure 2. Concentrations of cesium-137 in bottom-sediment cores at four sites in Lake Mead, May 1998, and in the atmosphere, 1952-72. Solid circles represent cesium-137 concentrations. Open circles represent cesium-137 concentrations that are less than the value plotted. Triangles represent atmospheric cesium-137 concentrations divided by the peak concentration.
