Final answer:

Half-life is the time needed for half of a radioactive material to decay. To find the remaining substance after certain half-lives, simply halve the amount. The biological half-life involves the elimination of half the substance from the body over a period.


Explanation:

Half-life is the amount of time needed for half of a radioactive material to decay. For example, if a substance has a half-life of 10 years, after 10 years, half of the material will have decayed.

To determine the amount of radioactive substance remaining after a given number of half-lives, you simply take half of the current amount for each half-life that has passed. This process continues with each successive half-life.

The biological half-life refers to the time required to eliminate half the quantity of a substance from the body.
