A curie is the unit of:
Correct answer: C. Radioactivity
- A. Energy
- B. Intensity
- C. Radioactivity
- D. Half-life
Explanation
The curie (Ci) is a non-SI unit of radioactivity, representing a large number of nuclear disintegrations per second (specifically, 3.7 × 10¹⁰ decays per second). It is named in honor of Marie and Pierre Curie.

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.
