# The initial concentration of a radioactive substance is N_{o} and its half life is 12 hours. What will be its concentration after 36 hours?

Answer :

In radioactive decay, nuclear half life expresses the time required for half of a sample to undergo radioactive decay.

Exponential decay can be expressed mathematically as

Where, N is concentration after t time, N_{o} is initial concentration,

t is time and is half life.
