Question:

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:

Options:

$T_{\frac{1}{2}}=\tau \ln 2$

$\tau=T_{\frac{1}{2}} \ln 2$

$T_{\frac{1}{2}}=\frac{1}{\tau}$

$T_{\frac{1}{2}}=\tau$

Correct Answer:

$T_{\frac{1}{2}}=\tau \ln 2$

Explanation:

relation between the half-life (T) of a radionuclide with its mean life (τ) is expressed as $T_{\frac{1}{2}}$ = τ ln2.
