The relation between half-life of a radio nuclide denoted by $T_{\frac{1}{2}}$ and average life of a radio nuclide denoted by $\tau$, is:
Answer & explanation
Correct answer: option 1
relation between the half-life (T) of a radionuclide with its mean life (τ) is expressed as $T_{\frac{1}{2}}$ = τ ln2.
