16 hours.
I assume you mean "half life". That means, how long does it take for half of the atoms in a sample to decay.
One-half of the original amount. That's precisely the definition of "half-life".
The length of time it takes for half of a radioactive sample to decay
18 days
Half life is the time taken for approximately half of the available nuclei in a sample of radioactive material to decay into something else. It's a characteristic of the isotope, for example, the half life of the isotope of iodine, I131 is 8.08 days. Half lives can vary from fractions of a second to thousands of years.
