The graph shows the activity "R" as a function of time "t" for three radioactive samples. Rank the samples according to their half-lives, shortest to longest.
Correct answer: A. 1, 2, 3
- A. 1, 2, 3
- B. 2, 1, 3
- C. 1, 3, 2
- D. 2, 3, 1
Explanation
More Steeper the curve means less half-life of sample.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
