Preliminary Study of the Role of Aerosols in the Transfer of Certain Radionuclides from the Marine Environment to the Land Environment

摘要

The radioactivity of a land lichen Ramalina scopulorum was observed in a coastal area of the Cotentin. Measurements of sup 106 Ru, sup 137 Cs, sup 144 Ce, sup 238 Pu, sup 239 Pu, and sup 240 Pu showed a decrease in the radioactivity of the species with increasing distance from the shore. The observed gradients might be the result of a transfer of radionuclides by aerosols from the marine environment to the land environment. (ERA citation 11:006251)
