Question
After 3 half lives a radionuclide is reduced in activity to what percentage of its initial activity?
Select one:
a. 12.5%
b. 25%
c. 50%
d. 72.5%
Expert Solution
Step 1
Scenario- A radionuclide's activity is reduced after consecutive half lives.
Given :
Number of half lives
Step 2
Let initially radionuclide had activity A,
We know, where,
Decay constant
Number of nuclei present
Initial activity
After 3 half lives amount of nuclei remaining
So activity after 3 half lives would be
Step by step
