The half-life period of Radium is 1600 years. Its average lifetime will be:
Correct answer: B. 2319 years
- A. 3200 years
- B. 2319 years
- C. 4800 years
- D. 4217 years
Explanation
Average life : 1/ λ = T1/2 / 0.693 = 1600/ 0.693 = 2308 yearsThis is approximately equal to 2319 years.

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.
