  2. Bateman equation - Wikipedia

    en.wikipedia.org/wiki/Bateman_equation

    (this can be adapted to handle decay branches). While this can be solved explicitly for i = 2, the formulas quickly become cumbersome for longer chains. [3] The Bateman equation is a classical master equation where the transition rates are only allowed from one species (i) to the next (i+1) but never in the reverse sense (i+1 to i is forbidden).

  3. List of equations in nuclear and particle physics - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in...

    Quantity (common name/s) (Common) symbol/s Defining equation SI units Dimension Number of atoms N = Number of atoms remaining at time t. N 0 = Initial number of atoms at time t = 0

  4. Decay correction - Wikipedia

    en.wikipedia.org/wiki/Decay_correction

    The decay correct might be used this way: a group of 20 animals is injected with a compound of interest on a Monday at 10:00 a.m. The compound is chemically joined to the isotope copper-64, which has a known half-life of 12.7 hours, or 764 minutes.

  5. Specific activity - Wikipedia

    en.wikipedia.org/wiki/Specific_activity

    Another unit of activity is the rutherford, which is defined as 1 × 10 6 radioactive decays per second. The specific activity should not be confused with level of exposure to ionizing radiation and thus the exposure or absorbed dose , which is the quantity important in assessing the effects of ionizing radiation on humans.

  6. Nuclear densitometry - Wikipedia

    en.wikipedia.org/wiki/Nuclear_densitometry

    A density gauge being used to ensure proper compaction for the foundation of a school construction project.. Nuclear densitometry is a technique used in civil construction and the petroleum industry, as well as for mining and archaeology purposes, to measure the density and inner structure of the test material.

  7. List of elements by stability of isotopes - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by...

    Unstable isotopes decay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture. Many rare types of decay, such as spontaneous fission or cluster decay, are known. (See Radioactive decay for details.) [citation needed] Of the first 82 elements in the periodic table, 80 have isotopes considered to ...

  8. Committed dose equivalent - Wikipedia

    en.wikipedia.org/wiki/Committed_dose_equivalent

    "The calculation of the committed effective dose equivalent (CEDE) begins with the determination of the equivalent dose, H T, to a tissue or organ, T. Where D T ,R is the absorbed dose in rads (one gray, an SI unit, equals 100 rads) averaged over the tissue or organ, T, due to radiation type, R, and W R is the radiation weighting factor.

  9. Radiochemistry - Wikipedia

    en.wikipedia.org/wiki/Radiochemistry

    Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable).
