According to the law of radioactive decay, the rate of disintegration is directly proportional to:
Correct answer: D. Number of atoms present
- A. Pressure
- B. Density of substance
- C. Volume of substance
- D. Number of atoms present
- E. Temperature
Explanation
According to law of radioactive decay, the rate of disintegration is direct proportional to number of atoms present. So option D is the correcct answer.

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.
