Exempel på hur man kan använda CURIUM i en mening

• Berkelium was the fifth transuranium element discovered after neptunium, plutonium, curium and americium.
• This was then sent to the Metallurgical Laboratory at University of Chicago where a tiny sample of curium was eventually separated and identified.
• It was first synthesized in 1950 at Lawrence Berkeley National Laboratory (then the University of California Radiation Laboratory) by bombarding curium with alpha particles (helium-4 ions).
• During this time they discovered two new elements (95, americium and 96, curium), although publication was withheld until after the war.
• In 1965, californium-252, the heaviest isotope produced at SRP, was separated as a byproduct of the curium program.
• The heavier actinides, primarily americium and curium, and the fission products remain in the aqueous phase.
• 6 million years – orders of magnitude longer than that of any known isotope beyond curium, and long enough to study as a possible extinct radionuclide that would be produced by the r-process.
• The minor actinides include neptunium (element 93), americium (element 95), curium (element 96), berkelium (element 97), californium (element 98), einsteinium (element 99), and fermium (element 100).
• The three other possible forms which curium sesquioxide can take are the body-centered cubic form, the monoclinic form, and the hexagonal form.
• Major actinides is a term used in the nuclear power industry that refers to the isotopes of plutonium (239 Pu) uranium (235 U, 238 U) and thorium (232 Th) present in nuclear fuel, as opposed to the minor actinides neptunium, americium, curium, berkelium, and californium, including other isotopes of uranium and plutonium and other actinides.
• Przybylski's Star possibly also contains many different short-lived actinide elements, with actinium, protactinium, neptunium, plutonium, americium, curium, berkelium, californium, and einsteinium being theoretically detected.
• Pyroprocessing of nuclear fuel rods, as an alternative to nuclear reprocessing, only attempts to combine separated plutonium with other, such as neptunium, americium, or curium.
• 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.
• Elements 95 and 96, originally called "pandemonium" and "delirium", were eventually named americium and curium by analogy with the chemically related elements europium and gadolinium.
• The monopnictides of berkelium-249 are known for the elements nitrogen, phosphorus, arsenic These lattice constant values are smaller than those in curium pnictides, but are comparable to those of terbium pnictides.
• Californium polyborate is dangerous because of the radioactivity of californium and its decay daughter curium.
• ISO 13167:2015 Water quality - Plutonium, americium, curium and neptunium - Test method using alpha spectrometry.
• Sulfides, selenides and tellurides of curium have been obtained by treating curium with gaseous sulfur, selenium or tellurium in vacuum at elevated temperature.
