Discharges from nuclear plants within the nuclear fuel cycle introduce fission products to the environment. The releases from nuclear reprocessing plants tend to be medium to long-lived radioisotopes; this is because the nuclear fuel is allowed to cool for several years before being dissolved in the nitric acid.
Unfortunately, hydrological and geological conditions in Chernobyl area promoted rapid radionuclide migration to subsurface water network. These factors include flat terrain, abundant precipitation and highly permeable sandy sediments [4] Main natural factors of nuclides migration in the region can be divided into four groups, including: weather and climate-related (evaporation and ...
The isotope hydrology program at the International Atomic Energy Agency works to aid developing states to create a detailed portrait of Earth's water resources. [9] In Ethiopia, Libya, Chad, Egypt and Sudan, the International Atomic Energy Agency used radioisotope techniques to help local water policy identify and conserve fossil water.
Bioremediation of radioactive waste or bioremediation of radionuclides is an application of bioremediation based on the use of biological agents bacteria, plants and fungi (natural or genetically modified) to catalyze chemical reactions that allow the decontamination of sites affected by radionuclides.

The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge or a nuclear reactor containment breach, the air, soil, people, plants, and animals in the vicinity will become contaminated by nuclear fuel and fission products.
Residues from the oil and gas industry often contain radium and its daughters. The sulfate scale from an oil well can be very radium rich. The water inside an oil field is often very rich in strontium, barium and radium, while seawater is very rich in sulfate: so if water from an oil well is discharged into the sea or mixed with seawater, the radium is likely to be brought out of solution by ...
Noxious weeds can be deadly for humans, animals and other plants in your garden. Here’s how to identify a plants before you get hurt. You may have poison in your garden.
The second study had a wider scope, and was meant to study the geographic spread of more-radioactive isotopes, like tellurium and iodine. Because these isotopes deposit themselves in the soil with rain, Norikazu Kinoshita and his colleagues observed the effect of two specific rain-showers on 15 and 21 March 2011.
