Answer:
The half-life of a radioactive substance is the time the substance takes to be reduced by half of its initial amount as a consequence of decay.
Step-by-step explanation:
- The half-life of a radioactive substance is the time the substance takes to be reduced by half of its initial amount as a consequence of decay.
- It is a characteristic constant.
- It is known that the decay of a radioactive isotope isotope obeys first order kinetics.
- Also, it is clear that in first order decay the half-life time is independent of the initial concentration.
