Dayton Daily News investigation found #contamination, sick workers at #PiketonOhio plant
By Lynn Hulsey
May 15, 2019"A polluted former #UraniumEnrichment plant in #Piketon closed years ago but it's impact continues to resonate through the community, including this week when a #MiddleSchool was closed after traces of radioactive #neptunium were found at an air monitoring station at the school.
"Contamination with radiation and multiple toxic substances at the former Portsmouth Gaseous Diffusion Plant led to an ongoing, multibillion dollar environmental cleanup and sickened plant workers who had to fight for compensation as they battled debilitating terminal illnesses related to their years at the plant.
"A massive 2006 investigation by the Dayton Daily News found five plumes of poisoned #groundwater, contamination with radiation, #beryllium, polychlorinated biphenyls (#PCBs) and #asbestos.
"The investigation found lax safety practices, routine mishandling of toxic and #radioactive material and at least 400 accidental releases of #UraniumGas or toxic fluorine. Toxins were dumped into unlined #landfills and ditches and leached into #groundwater and the Little #BeaverCreek, a tributary of the #SciotoRiver.
"The plant was operated by the federal government and contractors from 1954 to 2001 and enriched uranium to high levels for #NuclearWeapons and #NuclearSubmarines and to lower levels for #nuclearpowerplants.

Wiener Forschende entwickeln neue Methoden, um menschengemachte radioaktive Spurenelemente in der Umwelt zu finden und damit Meeres- und Grundwasserströmungen nachzuvollziehen.
Dabei interessieren sich die Forschenden insbesondere für das radioaktive Element #Neptunium, ein gut geeigneter Umwelttracer. #scilog @univienna

Bacteria Neutralizing Nuclear Waste
by Robert Hayward | Apr 29, 2020
"This special kind of bacteria was discovered at a nuclear waste storage site in Siberia. At that point, it appeared to be a good tool for creating a natural barrier to the spread of radionuclides, such as #uranium and #neptunium. With further investigation, researchers from the Frumkin Institute of Physical Chemistry in Moscow and the Russian Academy of Sciences’ Federal Research Center for Biotechnology were able to find a way to successfully use these bacteria.
"The researchers were able to isolate certain microorganisms during their studies. Those microorganisms can be used as a safeguard to protect the environment from liquid radioactive waste. Scientists made this conclusion while they were conducting microbiological studies of groundwater. Specifically, they studied the groundwater from the Seversky deep radiation burial site in Siberia, which is where the liquid radioactive waste that comes from the Siberian Chemical Combine is kept.
"Their research suggests that the bacteria could be used to prevent dangerous radiation from spreading. That’s because these bacteria can convert radioactive ions into sedentary forms, which can stop the radiation from harming the environment. After further research, the scientists learned the exact conditions needed to make the bacteria work in this way, making neutralizing nuclear waste seem much more possible. However, there is much more to discover along with these findings."

"There have long been environmental concerns about the #Piketon site, which the federal government and private contractors operated from 1954 to 2001 to enrich #uranium for #NuclearWeapons and, later, for nuclear power plant fuel.
"In 2019, a nearby middle school was closed after a report was released revealing that previous testing at the school found traces of #neptunium, a #radioactive #carcinogen, according to the Dayton Daily News. In 2006, the Daily News found poisoned #groundwater, radioactive contamination, hundreds of accidental releases of #uranium gas or toxic fluorine, and other toxins that leached from unlined landfills and ditches into groundwater and a nearby creek."
