Web9 Mar 2014 · Ammo: 270 rounds; plentiful. Tips: Poor range and accuracy, but shoots bullets really fast and ammo is literally everywhere. Fire in short bursts to keep it accurate. The alt-fire grenade is useful but don’t shoot it too close. Personal weapon of choice in the coast levels (because of the ammo crate on the buggy) All but two elements up to bismuth (element 83) have an isotope that is practically stable for all purposes ("classically stable"), with the exceptions being technetium and promethium (elements 43 and 61). All elements from polonium (element 84) onward are measurably radioactive. Th is one of the two nuclides beyond bismuth (the other being U) that have half-lives measured in billions of …
WebPurpose: Thorium-226 (half-life 30.6 m) is a radionuclide of interest for use in targeted alpha therapy applications. Due to its short half-life, 226 Th must be provided through a radionuclide generator system from its parent 230 U (20.8 d). Furthermore, as the half-life of 226 Th is very short, it should be provided in a form that is directly amenable to use in … WebTh-230 has a half life of 75,584 yrs (Cheng et 35 al., 2013), and issourced from the radioactive decay of 234U in seawater.
