title: Activity of (239 + 240)Pu and 238Pu in atmospheric deposits.
abstract: Radioactive concentrations of (239 + 240)Pu and 238Pu were determined in rainwater samples collected at Badajoz (in a semi-arid zone in the south-west of Spain) from 1992 to 1996. Total plutonium deposition (including dry and wet deposition) was investigated during dry and wet periods. Anomalously high depositions of (239 + 240)Pu ((6.8 +/- 0.4) mBq/m2) and 238Pu ((2.2 +/- 0.2)mBq/m2) were found in the second-half of 1995. The 238Pu/(239 + 240)Pu activity ratio (0.32 +/- 0.04) obtained for that sample was higher than in global fallout.
