The intermediates in the thorium-232 decay chain are all relatively short-lived; the longest-lived intermediate decay products are radium-228 and thorium-228, with half lives of 5.75 years and 1.91 years, respectively. All other intermediate decay products have half lives of less than four days. [5] The following table lists the intermediate ...

While Rockstar has previously provided some support with the original Grand Theft Auto and Grand Theft Auto 2, and even used a third-party utility for developing the Grand Theft Auto: London expansion packs, [40] the only official modification tool Rockstar has released is Rockstar Editor, [41] a tool which allows users to record and edit ...
Developed in tandem with the single-player mode, the online multiplayer mode Grand Theft Auto Online was conceived as a separate experience to be played in a continually evolving world. [81] Up to 30 players [n] freely roam across the game world and enter lobbies to complete jobs (story-driven competitive and cooperative modes). [82]
It mainly (98.62%) undergos beta decay, but sometimes (1.38%) it will undergo alpha decay instead. [ 1 ] 227 Ac is a member of the actinium series . It is found only in traces in uranium ores – one tonne of uranium in ore contains about 0.2 milligrams of 227 Ac.
Uranium-232 (232 U) is an isotope of uranium.It has a half-life of around 69 years and is a side product in the thorium cycle.It has been cited as an obstacle to nuclear proliferation using 233 U as the fissile material, because the intense gamma radiation emitted by 208 Tl (a daughter of 232 U, produced relatively quickly) makes the 233 U contaminated with it more difficult to handle.
Most of the time (92%), it undergoes beta plus decay to 230 Th, with a minor (8%) beta-minus decay branch leading to 230 U. It also has a very rare (.003%) alpha decay mode leading to 226 Ac. [10] It is not found in nature because its half-life is short and it is not found in the decay chains of 235 U, 238 U, or 232 Th. It has a mass of 230. ...
Decay modes in parentheses are still not observed through experiment but are, by their energy, predicted to occur. Numbers in brackets indicate probability of that decay mode occurring in %, tr indicate <0.1%. Spontaneous fission is not shown as a theoretical decay mode for stable nuclides where other modes are possible (see these nuclides).
