  • nucleus
  • It is sometimes noted that the time of the decay of the nucleus cannot be controlled, and that the finite half-life invalidates the result. (wikipedia.org)
  • This objection can be dispelled by sizing the hemispheres appropriately with regards to the half-life of the nucleus. (wikipedia.org)

  • One 2011 attempt from the German team at the GSI Helmholtz Centre for Heavy Ion Research had a suggestive but not conclusive result suggesting the possible production of 299Ubn, but there were several inconsistencies with the theoretically expected decay energies and half-lives of 299Ubn and its daughters and the implanting compound nucleus and evaporation residue could not be identified with certainty.

  • These studies suppose that cancers happen from residual tissue radiation damage caused by the I-131, and should appear mostly years after exposure, long after the I-131 has decayed. (wikipedia.org)
  • However, the long-term trend is for plant life to die off altogether. (wikipedia.org)
  • microsecond
  • The possibility of detection of elements 121 through 124 depends greatly on the theoretical model being used, as their half-lives are predicted to be very close to the one-microsecond border. (wikipedia.org)
  • single
  • By consideration of the normal process of quantum measurement, it is clear that if one detector registers the decay, then the other will not: a single particle cannot be detected by both detectors. (wikipedia.org)
  • Data
  • 5)Go back to your data table and for each three-second interval divide the number of candies decayed by the number previously remaining and multiply by 100. (prezi.com)
  • chain
  • A fourth decay chain was measured but was subsequently retracted. (wikipedia.org)
  • The extinction of plants will be the demise of almost all animal life, since plants are the base of the food chain on Earth. (wikipedia.org)
  • elements
  • For the property of radioactive elements , see Half-life (element) . (wikipedia.org)
  • Attempts to synthesize elements 119 and 120 push the limits of current technology, due to the decreasing cross sections of the production reactions and their probably short half-lives, expected to be on the order of microseconds. (wikipedia.org)
  • Ununennium and unbinilium (elements 119 and 120) are the lightest elements that have not yet been synthesized, and attempts to synthesize them would push the limits of current technology, due to the decreasing cross sections of the production reactions and their probably short half-lives, expected to be on the order of microseconds.
