Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
Radioactive contamination is a potential danger for living organisms and results in external hazards, concerning radiation sources outside the body, and internal dangers, as a result of the incorporation of radionuclides inside the body (often by inhalation of particles or ingestion of contaminated food). [14] In humans, single doses from 0.25 ...
A paper has been written on the radioactivity in oysters found in the Irish Sea, these were found by gamma spectroscopy to contain 141 Ce, 144 Ce, 103 Ru, 106 Ru, 137 Cs, 95 Zr and 95 Nb. [citation needed] In addition, a zinc activation product (65 Zn) was found, this is thought to be due to the corrosion of magnox fuel cladding in cooling ...
Dust and water leaving tailing sites may carry long-lived radioactive elements that enter water sources and the soil, increase background radiation, and eventually be ingested by humans and animals. A 2013 analysis in a medical journal found that, "The effects of all these sources of contamination on human health will be subtle and widespread ...
In a 1999 report by the International Atomic Energy Agency titled "Inventory of radioactive waste disposals at sea," a grainy map shows that at least 56,261 containers of radioactive waste were ...
The first conversations surrounding dumping radioactive waste into the ocean began in 1958 at the United Nations Law of the Sea Conference (UNCLOS). [12] The conference resulted in an agreement that all states should actively try to prevent radioactive waste pollution in the sea and follow any international guidelines regarding the issue. [12]
After sampling water sites around the country, the Surfrider Foundation, an ocean protection advocacy organization, found unsafe levels of fecal contamination at 19% of the 9,095 water samples. Of ...
Seoul office worker Kim Mijeong said she intends to stop eating seafood because she deeply mistrusts the safety of Japan’s release of treated radioactive wastewater into the sea from its ...
