In the case of a radioisotope , the value of `t_(1//2)` and `lambda` are identical in magnitude. The value is

Options

A. 1/0.693
B. `(0.693)^(1//2)`
C. 0.693
D. `(0.693)^(1//2)`

Answer

D

Explanation

`(t)/(t_(1//2))=(0.693)/(lambda)therefore t_(1//2)xxlambda=0.693`
Let `t_(1//2)=lambda=x` (Say)
or `"x" xx "x"=0.693` i.e., `x^(2)=0.693`
or `x=(0.693)^(1//2)`
