The decay constant for spontaneous fission of natural uranium has been determined by accumulating fission fragment tracks in Lexan plastic held adjacent to uranium metal for one year. The value, 6.8 ± 0.6. 1017 yr1, is consistent with values most commonly used in fission track dating....

The decay constant is a measure of how quickly on average a radioactive nuclei will take to decay. Since radioactive decay is a random process, the decay of a single nucleus may happen at any time but for many undecayed nuclei, the average decay rate is given by the decay constant, λ...
thesis of Marie Curie one finds the description of the search, with negative results, for a difference in the activity of uranium ores between midday and midnight. Recently, in particular since 2009 [1], various experiments have reported evidence of a time modulation of the decay constant of ...
where, for a given radionuclide, λ is the decay constant [λ=(ln2)/t 1/2] with t 1/2 the half-life, N A is the Avogadro number (6.022×1023 mol−1), and A is the atomic mass. From (11.52) we note that specific activity a is inversely proportional to both the half-life ...
What is the half life of U-238 for alpha decay? What is the decay constant? How can you calculate half-life of radioactive decay? What is the reaction decay of Thorium (232), via alpha decay? What is radioactivity in nuclear physics?
