The unit of decay constant is:
Correct answer: D. s^-1
- A. m/s
- B. m^-1
- C. m
- D. s^-1
Explanation
D is the right option because The decay constant, denoted by λ (lambda), represents the probability per unit time that a nucleus will decay. Its unit is per second (s^-1) because it measures the rate of decay over time.

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.
