Safecast (organization)
Safecast is an international, volunteer-centered organization devoted to open citizen science for environmental monitoring. Safecast was established by Sean Bonner, Pieter Franken, and Joi Ito shortly after the Fukushima Daiichi nuclear disaster in Japan, following the Tōhoku earthquake on 11 March 2011 and manages a global open data network for ionizing radiation and air quality monitoring. The Safecast team, with help of International Medcom, Tokyo hackerspace, and other volunteers, has designed varioudevicesfor radiation mapping. Haiyan Zhang developed a widely used interactive map of radiation levels around Japan, and was a mapping consultant in the formative phase of Safecast. The Geiger counter-like devices developed include the bGeigie and bGeigie Nano for mobile applications (carborne and walking measurements) as well as fixed stations called Pointcast. Despite being a citizen science project, professional quality and scientific grade data was sought from the onset, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crowdmapping
Crowdmapping is a subtype of crowdsourcing by which aggregation of crowd-generated inputs such as captured communications and social media feeds are combined with geographic data to create a digital map that is as up-to-date as possible on events such as wars, humanitarian crises, crime, elections, or natural disasters. Such maps are typically created collaboratively by people coming together over the Internet. The information can typically be sent to the map initiator or initiators by SMS or by filling out a form online and are then gathered on a map online automatically or by a dedicated group. In 2010, Ushahidi released "Crowdmap" − a free and open-source platform by which anyone can start crowdmapping projects. Uses Crowdmapping can be used to track fires, floods, pollution, crime, political violence, the spread of disease and bring a level of transparency to fast-moving events that are difficult for traditional media to adequately cover, or problem areas and longer- ...

Red Forest
The Red Forest ( uk, Рудий ліс, , ) is the area surrounding the Chernobyl Nuclear Power Plant within the Exclusion Zone, located in Polesia. The name "Red Forest" comes from the ginger-brown colour of the pine trees after they died following the absorption of high levels of ionizing radiation as a consequence of the Chernobyl nuclear disaster on 26 April 1986. In the post-disaster cleanup operations, the Red Forest was bulldozed and buried in "waste graveyards"; the site remains one of the most contaminated areas in the world today. Disaster and cleanup The Red Forest is located in the zone of alienation; this area received the highest doses of radiation from the Chernobyl accident and the resulting clouds of smoke and dust, heavily polluted with radioactive contamination. The trees died from this radiation. The explosion and fire at the Chernobyl No. 4 reactor contaminated the soil, water and atmosphere with radioactive material equivalent to that of 20 times the atomi ...

Capture Of Chernobyl
During the 2022 Russian invasion of Ukraine, the Chernobyl Exclusion Zone was captured on 24 February (the first day of the invasion) by the Russian Armed Forces, who entered Ukrainian territory from neighbouring Belarus and seized the entire area of the Chernobyl Nuclear Power Plant by the end of that day. On 7 March, it was reported that around 300 people (100 workers and 200 security guards for the plant) were trapped and had been unable to leave the power plant since its capture. On 31 March, it was reported that most of the Russian troops occupying the area had withdrawn, as the Russian military abandoned the Kyiv offensive to focus on operations in Eastern Ukraine. Background The Chernobyl disaster in 1986 released large quantities of radioactive material from the Chernobyl Nuclear Power Plant into the surrounding environment. The area in a radius surrounding the exploded reactor was evacuated and sealed off by Soviet authorities. This area was formalised as the Chern ...

2022 Russian Invasion Of Ukraine
On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. An estimated 8 million Ukrainians were displaced within their country by late May and 7.8 million fled the country by 8 November 2022, while Russia, within five weeks of the invasion, experienced its greatest emigration since the 1917 October Revolution. Following the 2014 Ukrainian Revolution, Russia annexed Crimea, and Russian-backed paramilitaries seized part of the Donbas region of south-eastern Ukraine, which consists of Luhansk and Donetsk oblasts, sparking a regional war. In March 2021, Russia began a large military build-up along its border with Ukraine, eventually amassing up to 190,000 troops and their equipment. Despite the build-up, denials of plans to invade or attack Ukraine were issued by various Russian gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Atomic Energy Agency
The International Atomic Energy Agency (IAEA) is an intergovernmental organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for any military purpose, including nuclear weapons. It was established in 1957 as an autonomous organization within the United Nations system; though governed by its own founding treaty, the organization reports to both the General Assembly and the Security Council of the United Nations, and is headquartered at the UN Office at Vienna, Austria. The IAEA was created in response to growing international concern toward nuclear weapons, especially amid rising tensions between the foremost nuclear powers, the United States and the Soviet Union. U.S. President Dwight D. Eisenhower's " Atoms for Peace" speech, which called for the creation of an international organization to monitor the global proliferation of nuclear resources and technology, is credited with catalyzing the formation of the IAEA, whose treaty came into ...
