The half-life of radioactive elements depends upon:
Correct answer: D. None of the above
- A. Amount of sample present
- B. Pressure
- C. Temperature
- D. None of the above
Explanation
Half-life is an intrinsic nuclear property of a specific isotope. It is not affected by external environmental factors such as the amount of the sample, pressure, or temperature.

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.
