“…The overall recoveries of 242 Pu was about 80%. Pu was electroplated onto stainless steel disks after purification and measured using an alpha-spectrometry system with passivated implanted planar silicon (PIPS) detectors of the 450 mm 2 active area (AMETEK, Oak Ridge, Tenn., USA) [21].…”

“…The main sources of plutonium in the watershed are the radioactive contamination from the global fallout from nuclear weapon testing and the Chernobyl Accident [18,19,20]. Published data indicate that the activity of 239,240 Pu reaches 15 Bq/m 2 in the lagoon sediments, 1.5 µBq/L in the waters and up to 1.3 Bq/kg in the suspended sediments [11,21].…”

The Curonian Lagoon is a unique system that is a temporary reservoir of water, accumulating about 62% of the suspended solids in the river runoff. The average activity of plutonium in the suspended particulate matter in the water of the Neris River was 0.26±0.02 Bq/kg, and the activity of 137Cs ranged from 23±8 to 49±12 Bq/kg. The average 137Cs flux to the Curonian Lagoon in the particulate and dissolved species was estimated to be (78±61) × 109 Bq/year. Preliminary estimates indicate that the annual input of 239,240Pu from the Neman River into the Curonian Lagoon is about 0.9 GBq, of which 0.56 GBq accumulates in the sediment of the lagoon.
