What is radioactive half-life?
The radioactive half-life.
Answer to Problem 5RQ
The time duration in which a radioactive element loses half of its volume compared to initial volume is known as the half-life of that element.
Explanation of Solution
There are some elements in nature, which releases some energy continuously. These elements can sometimes be used in energy generation. For example, uranium, plutonium, and many more. But while radiating energy, these elements gradually lose their mass.
A time duration in which a radioactive element loses half of its amount compared to its initial mass is known as the radioactive element's half-life.
In other words, a time gap in which decay of half of the radioactive element takes place is known as the half-life of that element.
Conclusion:
Therefore, the time duration in which a radioactive element loses half of its volume compared to initial volume is known as the half-life of that element.
