Relationships between deposition of Chernobyl originating caesium and ruthenium radionuclides and rainfall in Ireland.
Deposition data for caesium and ruthenium radionuclides in Ireland as a result of the Chernobyl accident were obtained by high-resolution gamma-ray spectrometry of soil samples taken at 111 locations throughout the country. Investigation of the relationships between deposition and recorded rainfall in relevant periods enabled an assessment to be made of the activity concentration within the plume during the wash-out phase. Detailed surveys in two regions of the country enabled a comparison to be made of the relative deposition of ruthenium and caesium isotopes. No evidence was found to suggest any difference in wash-out ratios for the two ruthenium isotopes.
