One radioisotope used for the dating of rocks and fossils

During this processing, depleted uranium (DU), enriched in U-238 and depleted in U-235, is produced.

U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146.

Because uranium is radioactive, it is constantly emitting particles and changing into other elements.

Uranium naturally contains all three isotopes (U-238, U-235 and U-234), and it rarely varies more than 0.01% from the average composition shown in the table below without our intervention.

To produce fuel-grade uranium, the uranium has to be processed to produce uranium dioxide and to enrich or concentrate the U-235 in the fuel pellets.

Historically, their claim comes from the work of James Ussher, Bishop in the Church of Ireland, from 1625 to 1656.
