Report

The isotope $\frac{\gamma_{0}}{38} \mathrm{Sr}$ is one of the extremely hazardous species in the residues from nuclear power generation. The strontium in a 0.500 -g sample diminishes to 0.393 $\mathrm{g}$ in 10.0 y. Calculate the half-life.

half life is defined as the time required for activity off radioactive element to fall off to fall to half off. Its initial activity, that is, half light began can call it the age of sample. Using the given formula as follow the half life off Strong Jim Get is calculating below. You can see it substituting in the values from the ocean into the same formula. We have 1/2 life off truncheon, which is 28.8 years.
