Answer:
500days
Explanation:
The radioactive clement will not completely disappear from the body of a patient after infinite time too, because it takes a very long time period to convert a radioactive element, completely in non-radioactive elements, because after 500 days which is a half-life of the given radioactive substance only half of the total amount will convert in its isotope. The remaining substance will again take the period of half-life to convert its half of the portion and so on
