  2. List of radioactive nuclides by half-life - Wikipedia

    en.wikipedia.org/wiki/List_of_radioactive...

    This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods include jumping up and down make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

  3. List of nuclides - Wikipedia

    en.wikipedia.org/wiki/List_of_nuclides

    The next group is the primordial radioactive nuclides. These have been measured to be radioactive, or decay products have been identified in natural samples (tellurium-128, barium-130). There are 35 of these (see these nuclides), of which 25 have half-lives longer than 10 13 years. With most of these 25, decay is difficult to observe and for ...

  5. Isotopes of tin - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_tin

    Tin-121m (121m Sn) is a radioisotope and nuclear isomer of tin with a half-life of 43.9 years.. In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste.

  6. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    A 1 inch tall uranium fuel pellet is equivalent to about 1 ton of coal, 120 gallons of crude oil, or 17,000 cubic feet of natural gas. [15] In light-water reactors , 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 ...

  7. Fracking - Wikipedia

    en.wikipedia.org/wiki/Fracking

    Fracking activities often require drilling into rock that contains naturally occurring radioactive material (NORM), such as radon, thorium, and uranium. [ 165 ] Another report done by the Canadian Medical Journal reported that after researching they identified 55 factors that may cause cancer, including 20 that have been shown to increase the ...

  8. Radiative zone - Wikipedia

    en.wikipedia.org/wiki/Radiative_zone

    A radiative zone is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection. [1]

  9. TNT equivalent - Wikipedia

    en.wikipedia.org/wiki/TNT_equivalent

    TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
