The half-life of the radioactive sample is the time it takes to decay to its half amount of the unstable nuclei of its initial amount. It is radioactively decays to its half value or in simple words, it takes the time to decay an unstable nuclei to decay to its half value.

It can take milliseconds to million years to disintegrate the different unstable nuclei of a radioactive substance to disintegrate its half amount to a stable substance.

Explanation:

Aquifers are porous and permeable formations that stores ground water. The ground water system is made up of mostly fresh water.

  • An aquifer acts as a reserve for ground water in the environment.
  • By passing through different formations, water that recharges them are purified.
  • This makes them fresh and mostly free from salt intrusion

An aquifer is able to store this fresh water and it is is good prospect for sourcing ground water.
