Fission track dating ppt
Fission track dating is somewhat of an anomaly in the field of radiometric dating.All other radiometric dating techniques rely on the relative abundances of a known parent isotope of an element and its corresponding concentration of daughter decay products.Fission tracks are not strictly speaking radiogenic nuclides, but they are the damage tracks left by fission products, which represent a special kind of radiogenic nuclide.As such, the abundance of fission tracks in geological materials increases over time in the same way as a radiogenic isotope.
Conductors do not display fission tracks because the free movement of electrons in their lattice structure neutralises the charged damage zone.
If accelerated decay did occur then fission-track dating; like all other all radiometric dating methods; is hopelessly in error.
The presentation will start after a short (15 second) video ad from one of our sponsors.
Fission track dating, on the other hand, does not involve the measurement of daughter products, and the concentration of its parent isotope can be misleading because the parent element goes through other types of decay much more often than it goes through spontaneous fission.
Unlike any other dating methods, however, fission tracks leave physical evidence of a radioactive process.
