Nuclear Incident At Khabarovsk, Russia
On April 5, 2024, a state of emergency was declared in Khabarovsk, a city in Russia's Far East bordering China with a population of 630,000. Elevated Radiation levels were detected near a power pylon approximately 2.5 kilometers from residential buildings. The source of radiation was discovered to be a radioactive caesium capsule. Discovery and response On March 28, a potential radiation source was discovered at a power pylon 2.5 kilometers away from residential buildings in the industrial district of Khabarovsk. A resident alerted emergency services, however they only arrived on April 4. A Russian radiation control group ECHO arrived on April 3. They reported to Novaya Gazeta: "The citizen who discovered the radiation was simply passing by. I went out to look and found such an interesting "find" near the power line. Initially, the resident reported to the Ministry of Emergency Situations; they sent requests for several days. We, volunteers, visited the site on April 3." The vol ...

Radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. This includes: * ''electromagnetic radiation'' consisting of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and Gamma ray, gamma radiation (γ) * ''particle radiation'' consisting of particles of non-zero rest energy, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation * ''acoustics, acoustic radiation'', such as ultrasound, sound, and seismic waves, all dependent on a physical transmission medium * ''gravitational radiation'', in the form of gravitational waves, ripples in spacetime Radiation is often categorized as either ''ionizing radiation, ionizing'' or ''non-ionizing radiation, non-ionizing'' depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volt, electron volts (eV), which is enough to ionize atoms and molecul ...

Caesium
Caesium (IUPAC spelling; also spelled cesium in American English) is a chemical element; it has Symbol (chemistry), symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of , which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoricity, pyrophoric and reacts with water even at . It is the least electronegativity, electronegative stable element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite. Caesium-137, a fission product, is extracted from waste produced by nuclear reactor technology, nuclear reactors. It has the largest atomic radius of all elements whose radii have been measured or calculated, at about 260 picometres. The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the new ...

Nyonoksa Radiation Accident
The Nyonoksa radiation accident, Arkhangelsk explosion or Nyonoksa explosion () occurred on 8 August 2019 near Nyonoksa, a village under the administrative jurisdiction of Severodvinsk, Arkhangelsk Oblast, Russian Federation. Five military and civilian specialists were killed and three (or six, depending on the source) were injured. Background Between November 2017 and 26 February 2018, Russia conducted four tests of the 9M730 Burevestnik nuclear-powered cruise missile, launched from other test sites. According to the United States intelligence community, only the flight test in November 2017 from Pankovo test site was moderately successful with all of the others ending in failure. According to Russia, none of the tests ended in failure. During recovery efforts later in 2018, Russia used three ships, one capable of handling radioactive material from the weapon nuclear core, to bring the missile tested in November 2017 from the seabed of Barents Sea back to the surface.

Chernobyl Disaster
On 26 April 1986, the no. 4 reactor of the Chernobyl Nuclear Power Plant, located near Pripyat, Ukrainian Soviet Socialist Republic, Ukrainian SSR, Soviet Union (now Ukraine), exploded. With dozens of direct casualties, it is one of only two nuclear energy accidents rated at the maximum severity on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear accident. The response involved more than Chernobyl liquidators, 500,000 personnel and cost an estimated 18billion Soviet ruble, rubles (about $84.5billion USD in 2025). It remains the worst nuclear disaster and the List of disasters by cost, most expensive disaster in history, with an estimated cost of US$700 billion. The disaster occurred while running a test to simulate cooling the reactor during an accident in blackout conditions. The operators carried out the test despite an accidental drop in reactor power, and due to a design issue, attempting to shut down the reactor in those conditio ...
