Half-life of Radium is 1590 years. In how many years will the Earth loss all its radium due to radioactive decay?
Correct answer: D. Never
- A. 1590 x 10^6 years
- B. 1590 x 10^25 years
- C. 1590 x 10^12 year
- D. Never
Explanation
The following is the solution: No radioactive element can completely decay. It is due to the reason that in any half-life period only half of the nuclei decay and in this way an infinite time is required for all the atoms to decay.

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.
