The decay constant of radioactive substance is `4.33 xx 10^(-4)` per year. Calculate its half life period .

Explanation

Here, `lambda = 4.33xx 10^(-4)` per year
`t_(1//2) = (0.6931)/(lambda)`
`:. t_(1//2) = (0.6931)/(4.33 xx 10^(-4))`
`:. t_(1//2) = 1600.6928` years
or `t_(1//2) = 1,600.6928 xx 365` days
`:. t_(1//2) = 584252` days
