A laboratory study is made of Tc, Np, and Pu accumulation by natural and sterilized silts collected from two typical eutrophic and dystrophic lakes of the Moscow oblast. After a short inductive period (1-3 days), the rate of Tc uptake by the eutrophic lake silt is about twice that by the dystrophic lake silt (at a dry solid to liquid phase ratio of 0.033 g ml-1). The rate is only slightly temperature-dependent, being practically constant (at a level of about 3% per day) under certain conditions… 

Technetium Stabilization in Low-Solubility Sulfide Phases: A Review

Technetium contamination remains a major environmental problem at nuclear reprocessing sites, e.g., the Hanford Site, Washington, USA. At these sites, Tc is present in liquid waste destined for

Plutonium isotopes in ecosystem of a running shallow lake

The aim of the present work is to get information on the possibilities of the shallow lake self-cleaning from plutonium isotopes using Lake Žuvintas as an object of study. A choice of the object is

Bioremediation of radioactive waste: radionuclide-microbe interactions in laboratory and field-scale studies.

Interaction of biomass of aerobic bacteria and fungi with Pu(IV) at low pH

TLDR
All the microorganisms tested demonstrate quite a fast process of Pu biosorption under the experimental conditions and have shown that all bacteria and fungi can very slightly alter oxidation states of Pu due to their microbial activity.

Treatment of liquid radioactive waste using microorganisms

The article deals with the problem of managing liquid nitrate-containing radioactive waste. A fundamentally new method for preliminary treatment that allows one to decrease the volume of these waste

Kinetics of the formation of precipitates and the physicochemical properties of technetium-99 and rhenium sulfides according to small-angle X-ray scattering and ultramicrocentrifugation data

The interaction of technetium and rhenium with sulfides in aqueous solutions was studied by small-angle X-ray scattering and ultramicrocentrifugation. It was shown that, although the stoichiometry of

Radiobiology of Select Radionuclides in Hanford Site Tank Waste.

ABSTRACT There are several important radionuclides involved in the "clean-up" or environmental isolation of nuclear waste contained in US Department of Energy Hanford Site underground waste tanks
