Exempel på hur man kan använda TRANSURANIC i en mening

• It is radioactive and a transuranic member of the actinide series in the periodic table, located under the lanthanide element europium and was thus named after the Americas by analogy.
• This transuranic actinide element was named after eminent scientists Marie and Pierre Curie, both known for their research on radioactivity.
• The transuranium (or transuranic) elements are the chemical elements with atomic number greater than 92, which is the atomic number of uranium.
• The Waste Isolation Pilot Plant, or WIPP, in New Mexico, US, is the world's third deep geological repository (after Germany's Repository for radioactive waste Morsleben and the Schacht Asse II salt mine) licensed to store transuranic radioactive waste for 10,000 years.
• Low-level waste (LLW) or low-level radioactive waste (LLRW) is nuclear waste that does not fit into the categorical definitions for intermediate-level waste (ILW), high-level waste (HLW), spent nuclear fuel (SNF), transuranic waste (TRU), or certain byproduct materials known as 11e(2) wastes, such as uranium mill tailings.
• He also discovered the uranium-237 isotope and pioneered the studies of symmetric fission phenomena occurring upon fast neutron irradiation of uranium (1939–1940), and narrowly missed out on the discovery of the first transuranic element, neptunium.
• The long-lived transuranic elements in nuclear waste can in principle be fissioned, releasing energy in the process and leaving behind the fission products which are shorter-lived.
• Because the lead isotopes are created by decay of different transuranic elements, the ratios of the four lead isotopes to one another can be very useful in tracking the source of melts in igneous rocks, the source of sediments and even the origin of people via isotopic fingerprinting of their teeth, skin and bones.
• Wu's PhD dissertation dealt with theoretical predictions of the chemical properties of the yet undiscovered transuranic elements of the actinide series, which includes such well known elements as plutonium and americium.
• In addition, the dioxides of cerium, thorium, and the transuranic elements from neptunium through californium have the same structures.
• Glenn Theodore Seaborg, one of the researchers who synthesized transuranic elements, proposed the actinide concept in 1944 as an explanation for observed deviations and a hypothesis to guide future experiments.
• Seaborg, Nobel Prize laureate, chemist prominent in the discovery and isolation of ten transuranic elements including plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium and seaborgium, which was named in his honor.
• Historically a variety of isotopes such as radium (Ra-226) were used, but in modern times the transuranic isotopes Am-241 and Pu-239 are almost exclusively used in AmBe and PuBe neutron sources, respectively.
• Starke discovered the transuranic element neptunium (atomic number 93), independently from the American team of Edwin McMillan and Philip Abelson.
• The transuranic element flerovium was named after the Flerov Laboratory of Nuclear Reactions, which in turn was named after Georgy Flyorov.
• He was part of the Berkeley team that claimed discovery of the synthetic transuranic elements of nobelium and lawrencium.
• Becoming a member of staff at the Fisheries Radiobiological Laboratory in 1969, Pentreath carried out research into the behaviour, fate, and accumulation of various radionuclides (fission and neutron activation products, and those of the transuranic series) by marine fish and shellfish as well as the use of radiotracers to study various marine pollutants, being awarded a DSc (London) in 1980.
