After two half-lives has passed, the radioactivity of a substance is zero [1] The volume of blood in a person s body can be measured using radioactivity. A small quantity of a radioactive substance is injected into the body. After an hour, a small sample of blood is taken and its radioactivity is measured. The volume of blood can then be calculated.
