Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment.
Perak is a state of Malaysia on the west coast of the Malay Peninsula. Perak has land borders with the Malaysian states of Kedah to the north, Penang to the northwest, Kelantan and Pahang to the east, and Selangor to the south. Thailand's Yala and Narathiwat provinces both lie to the northeast. Perak's capital city, Ipoh, was known historically for its tin-mining activities until the price of the metal dropped, severely affecting the state's economy. The royal capital remains Kuala Kangsar, where the palace of the Sultan of Perak is located. As of 2018, the state's population was 2,500,000. Perak has diverse tropical rainforests and an equatorial climate. The state's mountain ranges belong to the Titiwangsa Mountains, which is part of the larger Tenasserim Hills system that connects Myanmar, Thailand and Malaysia.
Ozyorsk or Ozersk is a closed city in Chelyabinsk Oblast, Russia. It has a population of 82,164 as of the 2010 census.
The North–South Expressway Northern Route is an interstate controlled-access highway running parallel to the northwestern coast of Peninsular Malaysia. The 460-kilometre (290-mile) expressway forms the north section of the North–South Expressway, passing through the northwestern states of Kedah, Penang, Perak and Selangor. The expressway begins at the Bukit Kayu Hitam checkpoint in Kedah, where the Malaysia–Thailand border lies, and ends at Bukit Lanjan in Selangor state where the expressway interchanges with the New Klang Valley Expressway. The expressway is operated by PLUS Expressways.
Bukit Merah may refer to a town in Kerian District or the other in Kinta District, Perak, Malaysia.
Bukit, the Indonesian or Malay word for hill, may refer to:
Mayapuri is an industrial locality in the West Delhi district of Delhi, India. It used to be a major hub of heavy metal and small-scale industries, but following government sanctions, most of the heavy metal industries moved out. The place is now a combination of light metal factories, scrap markets, and automobile service stations. In 2010, a major radiation accident took place in the scrap yards of Mayapuri.
Nuclear entombment is a method of nuclear decommissioning in which radioactive contaminants are encased in a structurally long-lived material, such as concrete. This prevents radioactive material and other contaminated substances from being exposed to human activity and the environment. Entombment is usually applied to nuclear reactors, but also some nuclear test sites. Nuclear entombment is the least used of three methods for decommissioning nuclear power plants, the others being dismantling and deferred dismantling. The use of nuclear entombment is more practical for larger nuclear power plants that are in need of both long and short term burials, as well as for power plants which seek to terminate their facility licenses. Entombment is used on a case-by-case basis because of its major commitment with years of surveillance and complexity until the radioactivity is no longer a major concern, permitting decommissioning and ultimate unrestricted release of the property. Considerations such as financial backing and the availability of technical know-how are also major factors.
High-level radioactive waste management addresses the handling of radioactive materials generated from nuclear power production and nuclear weapons manufacture. Radioactive waste contains both short-lived and long-lived radionuclides, as well as non-radioactive nuclides. In 2002, the United States stored approximately 47,000 tonnes of high-level radioactive waste.
Malaysia faces several environmental issues. Malaysia's environment possesses megadiverse biological diversity, with globally significant endemism and biodiversity, but is threatened by several issues. Deforestation is a major issue in the country that has led to many species becoming threatened with extinction. As a major economic sector, palm oil production has had a substantial environmental impact. Air pollution is also a major issue, with the country one of the most affected countries by seasonal Southeast Asian haze. The country is also affected by climate change.
Malaysian Sikhs are known to be the fourth largest Malaysian Indian ethnic group. It is estimated that there are around 100,000 Sikhs in Malaysia.
Environmental issues in Russia include pollution and erosion, and have impacts on people, wildlife and ecosystems.
The Fukushima disaster cleanup is an ongoing attempt to limit radioactive contamination from the three nuclear reactors involved in the Fukushima Daiichi nuclear disaster that followed the earthquake and tsunami on 11 March 2011. The affected reactors were adjacent to one another and accident management was made much more difficult because of the number of simultaneous hazards concentrated in a small area. Failure of emergency power following the tsunami resulted in loss of coolant from each reactor, hydrogen explosions damaging the reactor buildings, and water draining from open-air spent fuel pools. Plant workers were put in the position of trying to cope simultaneously with core meltdowns at three reactors and exposed fuel pools at three units.
From 1946 through 1993, thirteen countries used ocean disposal or ocean dumping as a method to dispose of nuclear/radioactive waste with an approximation of 200,000 tons sourcing mainly from the medical, research and nuclear industry.
The Greater Penang Conurbation, also known as the George Town Conurbation, is the built-up urban or metropolitan area within and around the Malaysian state of Penang. Encompassing all of Penang, and parts of the neighbouring states of Kedah and Perak, the conurbation was home to over 2.84 million people as of 2020, the second largest in the country after the Klang Valley.
Lake Karachay was a small natural lake in eastern Russia. It is best known for its use as a dumping ground by the Soviet Union's Mayak nuclear weapons laboratory and fuel reprocessing plant. A string of accidents and disasters at the Mayak facility has contaminated much of the surrounding the area with highly radioactive waste. In the 1960s, the lake began to dry out and its area had dropped from 0.5 km2 in 1951 to 0.15 km2 by the end of 1993. In 1968, following a drought in the region, the wind carried 185 PBq (5 MCi) of radioactive dust away from the dried bed of the lake, irradiating half a million people. Lake Karachay has been described as the "most polluted spot on Earth" by the Worldwatch Institute.
The 2015–16 Kuantan bauxite disaster is an ecological disaster which occurred from 2015 to 2016 onwards in Kuantan District of Pahang in Malaysia. The unscrupulous bauxite mining was blamed for causing soil pollution particularly along the lane of Kuantan highway where the lorries carrying bauxite which also spread to waters around the district, causing the environment to turn red as a result from unregulated mining activities that posed health hazards to both mine workers and the district surrounding communities lived along the mine routes.
The Department of Atomic Energy Malaysia, or formerly known as Atomic Energy Licensing Board or in Malay known as Lembaga Perlesenan Tenaga Atom (AELB), is a government agency under the Ministry of Science, Technology & Innovation (MOSTI) that is responsible for the regulation of atomic energy activities in Malaysia as stipulated in the Atomic Energy Licensing Act 1984.
The 2019 Kim Kim River toxic pollution is a water pollution incident that occurred on 7 March 2019 caused by illegal chemical waste dumping at the Kim Kim River in Pasir Gudang of Johor in Malaysia. The illegal dumping released toxic fumes, affecting 6,000 people and hospitalising 2,775. Most of the victims were school students—110 schools located near the river were subsequently closed.
