Radioactivity does not depend upon:
Correct answer: B. Temperature
- A. Initial number of atoms
- B. Temperature
- C. Nature of material
- D. Time
Explanation
Radioactivity is a process of spontaneous disintegration or breaking of unstable atomic nuclei by the emission of radiation like α−ray or β−ray or λ−ray. The radioactive process is spontaneous which means it occurs by itself. It cannot be initiated, stopped, accelerated or decelerated by external factors like by changing chemical conditions or by changing physical conditions like temperature or pressure.

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.
