The surface called "surface" means the lower boundary of the atmosphere. "Content" indicates a quantity per unit area. "Radioactivity" means the number of radioactive decays of a material per second. "Rn" means the element "radon" and "220Rn" is the isotope "radon-220" with a half-life of 6.37e-04 days. rdf:langString
