In radioactivity, the rate of decay:
Correct answer: D. is not effected by electric and magnetic field
- A. can be increased by magnetic field
- B. can be decreased by the magnetic fields
- C. can be kept constant by the electric field
- D. is not effected by electric and magnetic field
Explanation
Radioactivity is a spontaneous, random and natural phenomenon. So, it is not effected by electric and magnetic field

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.
