The rock sample's half-life span remains constant. It will always be 4.5×10⁹ years no matter how many times it is cutting process.

What is uranium?

Uranium, with the atomic number 92 and the symbol U in the periodic table, is a weakly radioactive element. One of the heavy metals that may be used as a concentrated energy source is uranium.

The element is found in various rocks in concentrations of 2 to 4 ppm (parts per million).

The rock sample's half-life span remains constant. It will always be 4.5×10⁹ years no matter how many times it is cutting process.

Hence the half-life of the uranium remains unchanged.
