Curie is the unit of?
Correct answer: A. Radioactivity
- A. Radioactivity
- B. Temperature
- C. Half life
- D. Transition of magnetism
Explanation
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability.This was discovered by Henri becquerel in 1896.It emits radioactive elements viz- alpha, beta, gamma rays.A curie is a non-SI unit of radioactivity.The System International of units (SI system) uses the unit of becquerel (Bq) as its unit of radioactivity. One curie is equal to 37 billion Bq. 37 billion Bq = 1 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.
