Fallout of Pu-238 Over Madagascar Following the Snap 9A Satellite Failure

After the SNAP 9A satellite accident in 1964, the dispersion of Pu was investigated as a function of latitude North and South. It was obvious that most of the fallout of 238Pu was on the southern hemisphere. However no data from Madagascar, where the accident happened, were reported. This paper describes the analysis of peat bog samples for Pu-isotopes by alpha spectrometry after radiochemical separation. To investigate especially the presence of 239Pu, selected samples were analyzed for 239Pu and 240Pu using mass spectrometric analyses, AMS.
