What is the unit of decay constant?
Correct answer: D. sec-1
- A. Second
- B. Minute
- C. Hour
- D. sec-1
Explanation
The decay constant (λ) of a radioactive nuclide is its probability of decay per unit time. Therefore, its unit is sec-1.

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.
