Question

A newly prepared radioactive nuclide has a decay constant $\lambda$ of ${10}^{-6}{s}^{-1}$. What is the approximate half-life of the nuclide?

• A. $4$
• B. $1$ day
• C. $8$ week
• D. $12$ month

Answer 1

The correct option is C $8$ week

Given : $\lambda ={10}^{-6}{s}^{-1}$
$t_{1/2}=,\frac{ln2}{\lambda }=693147.18s=192hours=8.02days$
Order of a week.
