  2. Transuranium element - Wikipedia

    en.wikipedia.org/wiki/Transuranium_element

    The transuranium (or transuranic) elements are the chemical elements with atomic number greater than 92, which is the atomic number of uranium. All of them are radioactively unstable and decay into other elements. Except for neptunium and plutonium, which have been found in trace amounts in nature, none occur naturally on Earth and they are ...

  3. Superheavy element - Wikipedia

    en.wikipedia.org/wiki/Superheavy_element

    By definition, superheavy elements are also transuranium elements, i.e., having atomic numbers greater than that of uranium (92). Depending on the definition of group 3 adopted by authors, lawrencium may also be included to complete the 6d series. [2] [3] [4] [5]

    en.wikipedia.org/wiki/Transuranic_waste

    Transuranic waste (TRU) is stated by U.S. regulations, and independent of state or origin, to be waste which has been contaminated with alpha emitting transuranic radionuclides possessing half-lives greater than 20 years and in concentrations greater than 100 nCi/g (3.7 MBq/kg).

  6. Californium - Wikipedia

    en.wikipedia.org/wiki/Californium

    It was the sixth transuranium element to be discovered; the team announced its discovery on March 17, 1950. [29] [30] To produce californium, a microgram-size target of curium-242 (242 96 Cm) was bombarded with 35 MeV alpha particles (4 2 He) in the 60-inch-diameter (1.52 m) cyclotron at Berkeley, which produced californium-245 (245 98 Cf

    Like methadone, Suboxone blocks both the effects of heroin withdrawal and an addict’s craving and, if used properly, does it without causing intoxication. Unlike methadone, it can be prescribed by a certified family physician and taken at home, meaning a recovering addict can lead a normal life, without a daily early-morning commute to a clinic.
