Determination of uranium isotopes (234U, 238U) and natural uranium (U-nat) in water samples by alpha spectrometry

Background: Due to the potential public health effects of releases of uranium to the environment, isotopic determination and measurement of this radionuclide in environmental samples is very important. Achieving this goal, monitoring programs for this radionuclide seems necessary to be applied in many countries. Materials and Methods: The uranium was separated from the water samples using anion...

Culture-independent molecular analysis of bacterial diversity in uranium-ore/-mine waste-contaminated and non-contaminated sites from uranium mines

Soil, water and sediment samples collected from in and around Jaduguda, Bagjata and Turamdih mines were analyzed for physicochemical parameters and cultured, and yet to be cultured microbial diversity. Culturable fraction of microbial community measured as Colony Forming Unit (CFU) on R2A medium revealed microbes between 10(4) and 10(9) CFU/g sample. Community DNA was extracted from all the sam...

Bacteria in Uranium-Contaminated Sediments Undergoing Bioremediation

A 16S rRNA-targeted tunable bead array was developed and used in a retrospective analysis of metaland sulfate-reducing bacteria in contaminated subsurface sediments undergoing in situ U(VI) bioremediation. Total RNA was extracted from subsurface sediments and interrogated directly, without a PCR step. Bead array validation studies with total RNA derived from 24 isolates indicated that the behav...

Bioremediation of Uranium Contaminated Soils and Wastes

Contamination of soils, water, and sediments by radionuclides and toxic metals from uranium mill tailings, nuclear fuel manufacturing and nuclear weapons production is a major concern. Studies of the mechanisms of biotransformation of uranium and toxic metals under various microbial process conditions has resulted in the development of two treatment processes: (i) stabilization of uranium and t...

Removal of Uranium from Contaminated Water by Clay Ceramics in Flow-Through Columns

Uranium contamination of groundwater increasingly concerns rural residents depending on home wells for their drinking water in communities where uranium is a source of contamination. Established technologies to clean up contaminated aquifers are ineffective in large contaminated areas or are prohibitively expensive. Permeable reactive barriers (PRBs) are a low-cost alternative to these methods....
