Spontaneous fission can occur much more rapidly when the nucleus of an atom undergoes superdeformation.

Spontaneous fission gives much the same result as induced nuclear fission.

These trails, or fission tracks, are the foundation of the radiometric dating method called fission track dating.

Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.

The neutrons released can be used to inspect airline luggage for hidden explosives, to gauge the moisture content of soil in highway and building construction, or to measure the moisture of materials stored in silos, for example.

As long as the spontaneous fission gives a negligible reduction of the number of nuclei that can undergo such fission, this process can be approximated closely as a Poisson process.Spontaneous fission has never been observed in the naturally occurring isotopes of these elements, however. Spontaneous fission is feasible over practical observation times only for atomic masses of 232 amu or more.These are elements at least as heavy as thorium-232 – which has a half-life somewhat longer than the age of the universe.Spontaneous fission was identified in 1940 by Soviet physicists Georgy Flyorov and Konstantin Petrzhak The lightest natural nuclides that are hypothetically subject to spontaneous fission are niobium-93 and molybdenum-94 (elements 41 and 42, respectively).These could theoretically decay to calcium-46 and scandium-47 or titanium-48 respectively.A few examples of such lies are presented at the very bottom of this page.
