Interpretation:
Estimating the percentage of remaining radioisotope.
Concept introduction:
The period it takes for one-half of a radioactive isotope to decay is known as the half-life.
Answer to Problem 11STP
Explanation of Solution
In this problem, the given graph represents the decay curve for radioactive isotope where on the x-axis number of half-lives is given, and on the y-axis, the radioisotope remaining in
We need to determine the percentage of remaining radioisotope after
If we use
After 0.5 half-lives, we will have 50% more than after one half-life which is
This value can be confirmed if we simply find
