  2. Decay product - Wikipedia

    en.wikipedia.org/wiki/Decay_product

    In nuclear physics, a decay product (also known as a daughter product, daughter isotope, radio-daughter, or daughter nuclide) is the remaining nuclide left over from radioactive decay. Radioactive decay often proceeds via a sequence of steps ( decay chain ). For example, 238 U decays to 234 Th which decays to 234m Pa which decays, and so on, to ...

  3. Decay chain - Wikipedia

    en.wikipedia.org/wiki/Decay_chain

    The daughter of a daughter isotope is sometimes called a granddaughter isotope. Note that the parent isotope becomes the daughter isotope, unlike in the case of a biological parent and daughter. The time it takes for a parent atom to decay to its daughter nuclei can vary widely, based on the material's half-life.

  4. Radiometric dating - Wikipedia

    en.wikipedia.org/wiki/Radiometric_dating

    Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of ...

  5. Uranium-238 - Wikipedia

    en.wikipedia.org/wiki/Uranium-238

    Uranium-238. Uranium-238 ( 238U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor. However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to ...

  9. Radioactive decay - Wikipedia

    en.wikipedia.org/wiki/Radioactive_decay

    v. t. e. Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
