摘要
Atmospheric concentrations of Chernobyl-derived radio-nuclides collected on filters in College Park, Maryland during May, 1986 have been determined by gamma-ray analysis. Measurements indicate that following an extensive wash-out of radioactivity, Ru-103 was enriched in the upper atmosphere relative to Cs-137 and I-131. Absolute concentrations of particulate and gas-phase radionuclides and the observed enrichment of Ru-103 are in agreement with other studies.
