Chernobyl

Physicists say that the risk of nuclear material being released from the Chernobyl reactor as a result of Russian attack is minimal.

But Bruno Merk at the University of Liverpool, UK, says the risk of nuclear material being released from the decaying reactor as a result of the conflict is low. A researcher who monitors the ongoing emission of neutrons from the reactor to gauge safety spoke to New Scientist on 24 February, and says that staff at Chernobyl were safe. But physicists say the risk of radioactive emissions as a result of accidental damage is minimal.

The warning comes after workers at the plant were reportedly taken hostage by Russian troops, and radiation levels in the exclusion zone soared.

“If something hit the sarcophagus, you will feel it in the UK. The whole of Europe will feel it. Dr Lewis said the scale of increase was “still very very low. The humanitarian and environmental consequences of such a catastrophe will have no borders.” The nuclear elements inside are maintained in specific conditions, so if conditions worsened, there could be dispersion of radionuclides. “We’ll see if it returns to normal in several days. It is not a threat to life”. There are 22,000 spent fuel assemblies – structured groups of fuel rods – storing radioactive waste from the Chernobyl disaster. You would get contamination if it were to breach the core,” Dr Lewis said. “And I can’t imagine the Ukrainian engineers deliberately letting them go into meltdown, that would be disastrous for Ukraine. Oksana Ananyeva, energy policy expert at Ecoaction, said: “The Russians don’t know how to handle a situation – if there’s some problem with personnel, or even unintended damage. Today the site holds radioactive waste from the disaster, while an enormous “sarcophagus” covers the destroyed reactor. There could be some accident because they don’t know what they are doing.

"The chance of a major accident at a Ukrainian plant today is not microscopically small anymore, but the consequences are still very large," Acton said. "Chernobyl's in Ukraine, so I think from that perspective the Russians want to get ahold of everything in the country," Acton said. But Chernobyl might not actually be the biggest nuclear concern in Ukraine right now, said James Acton, the co-director of the Nuclear Policy Program at the Carnegie Endowment for International Peace.

Radiation levels increased, but a disaster at the defunct nuclear power plant there is 'extremely unlikely', experts say.

The radioactivity in the plant has decayed significantly since 1986. Ukraine's President Volodymyr Zelensky said Ukrainian officers fought to defend it, "so that the tragedy of 1986 will not be repeated." "And the thing that released the radioactivity then was a huge fire," said Prof Corkhill. But she stressed a repeat of that disaster was "extremely unlikely". But on Thursday, that jumped to 65 microSv/hrs - about five times more than you would get on one transatlantic flight. He called the Russian assault on Chernobyl a "declaration of war against the whole of Europe." Invading Russian troops took control of the plant - the site of the world's worst nuclear disaster in 1986 - on Thursday, Ukraine said.

“Radiation levels are normal in the NPP area. Russian President Vladimir Putin on Thursday ordered his troops to invade Ukraine and on the same day they seized the stricken Chernobyl nuclear power plant in one of the most radioactive places on Earth. Radiation levels increased at the Chernobyl Exclusion Zone, Ukraine authorities said on Friday, warning that the seizure of the nuclear plant by invading Russian troops could have “terrible consequences”.

The chemical structure of strontium-90 allows it to replace calcium and become assimilated in teeth and bones, exposing the body to radiation over a longer period with its half-life of 29 years. Cesium-137, with a half-life of 30 years, is one of the most common byproducts of fission; is highly radioactive, chemically reactive, and soluble; and is light enough that it spread the farthest of all the contamination. In the weeks following the accident, workers enclosed the reactor building—which still contains highly radioactive fuel material—in a concrete and steel structure called “the sarcophagus.” That eventually began to deteriorate. The Ukraine government said radiation monitors in the area showed a spike in radiation levels after the Chernobyl attack. On April 26 of that year, operators running a test lost control of the Number Four reactor, causing a fire that destroyed the building. Early on Thursday, Feb. 24, the first day of their invasion, Russian troops occupied Chernobyl, the site of a 1986 explosion that spewed radioactive material into the surrounding area.
