Fission track dating ppt
Another source of possible error for fission-track dating is the possibility that tracks could be made by isotopes with higher spontaneous fission rates than Uranium-238.Fission-track dating involves counting the damage tracks left fragments of the spontaneous fission Uranium-238.The spontaneous fission of Uranium-238 has a known rate, as such the number of tracks is theoretically related to the age of the sample.The fragments emitted by this fission process leave trails of damage (fossil tracks or ion tracks) in the crystal structure of the mineral that contains the uranium.
The process of track production is essentially the same by which swift heavy ions produce ion tracks.
Alpha decay typically occurs in nuclei that are so big that they can’t be stable.
