The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Russian and American nuclear wastes in the Arctic may release radiation as global heating melts the ice.


Climate change: Arctic’s unknown viruses’ and nuclear waste,  A rapidly warming Arctic could cause the spread of nuclear waste, undiscovered viruses and antibiotic resistant bacteria, a report has found. BBC, 2 Oct 21,

It said potential radioactive waste from Cold War nuclear submarines and reactors and damage from mining could be released as the ice melts.

The nine million square miles of Artic dates to about a million years old.

Co-author Dr Arwyn Edwards from Aberystwyth University said much of the Arctic is still unknown.

Writing in Nature Climate Change, Dr Edwards co-authored report with academics from universities in the United States and NASA’s Jet Propulsion Laboratory in Southern California.

The Arctic houses a diverse range of chemical compounds whether through natural processes, accidents or deliberate storage.

Nuclear waste, viruses and chemicals

Thawing permafrost, or permanently frozen land, has widely been seen as a contributor to greenhouse gas emissions as massive stores of Arctic soil carbon are released to the atmosphere as carbon dioxide and methane, as well as causing abrupt change to the landscape.

However, the research found the implications are more widespread and less understood – with potential for the release of nuclear waste and radiation, unknown viruses and other chemicals of concern.

Between 1955 and 1990, the Soviet Union conducted 130 nuclear weapons tests in the atmosphere and near surface ocean of the Novaya Zemlya archipelago off the coast of north-west Russia.

The tests used 224 separate explosive devices, releasing about 265 megatons of nuclear energy and more than 100 decommissioned nuclear submarines were scuttled in the nearby Kara and Barents seas.

Despite a Russian government launching a strategic clean-up plan, the review notes the area has tested highly for the radioactive substances caesium and plutonium, between undersea sediment, vegetation and ice sheets.

The United States’ Camp Century nuclear-powered under-ice research facility in Greenland also produced considerable nuclear and diesel waste.

Decommissioned in 1967, waste was left in the accumulating ice, which faces a longer term threat from changes to the Greenland Ice Sheet.

The 1968 Thule bomber crash in the same country also dispersed huge amounts of plutonium on the Greenland ice sheet……………………..

The report said despite its findings, it is still poorly understood and largely unquantified and further in-depth research in the area is vital to gain further insight into the risks………..   https://www.bbc.com/news/uk-wales-58724710
