Sequential extraction of plutonium from
plant Mayak reservoirs R-4 and R-17 bottom sediments
Abstract
Speciation of 238,239,240Pu in
bottom sediments of Production Association Mayak two reservoirs were investigated.
Maximum content of plutonium in reservoir R-17 was found in residual fraction.
In reservoir R-4 plutonium was distributed equal in bound to organic matter and
residual fractions. The fact, that plutonium exists in physico-chemically
immobile fractions indicate the its low biological its low biological
availability.
Key words: PA "Mayak", plutonium-238,
plutonium-239, plutonium-240, sequential extraction, bottom sediments.
