Abstract: Airborne particulate material was collected at Didcot (UK) in June 1959, a period of elevated atmospheric ¹³⁷Cs concentrations due to atmospheric weapons testing; in May 1986, during the peak of Chernobyl deposition; and in 1987, from a location close to the Sellafield reprocessing plant. The samples were selectively extracted chemically in an attempt to identify the different forms of radiocaesium. Approximately 70% of the Chernobyl material was found to be water-soluble, compared to only 8% of the weapons fallout and 50% of the Sellafield material.
