The rate of radioactive decay is directly proportional to the stability of the:
Correct answer: C. Isotope
- A. Medium
- B. Atmosphere
- C. Isotope
- D. Half life
Explanation
For a given number of atoms, isotopes with shorter half-lives decay more rapidly, undergoing a greater number of radioactive decays per unit time than do isotopes with longer half-lives.

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.
