Fallout Radionuclide Distribution in Lichen Communities near Thule
Concentrations of the worldwide fallout radionuclides manganese-54, zinc-65, strontium-90, cesium-137, and cerium-praseodymium-144, and naturally occurring potassium-40 were measured in 80 lichen species collected near Thule, Greenland, during July-August 1968. Emphasis was placed on 137Cs for detai...
