Radioactive material is deacign with `t_(1//2) = 30` days on being, separated into two fractions , one of the fracation, immediately after separation decays with `t_(1//2) = 2` days. The other fraction, immediately after separation, would show:

Options

A. Constant specific activitty
B. Increaing specific activity
C. Decay with `t_(1//2) = 30` day
D. Decay with `t_(1//2) = 28` day

Answer

`(b)`

Explanation

Specific activity = Activity per `g` of sample.
Since some amount is taken out, therefore specific activity increases after removal of one fraction.
