Answer 1

A.radioactive isotopes are used to detect medical problems.

C.Radioactive isotopes are used to treat some diseases.

D.radiation is used to kill cancer cells.

Answer 2

Step-by-step explanation:

A radioactive isotope is defined as two or more chemical species of an element which has different atomic mass with unstable nuclei. As these isotopes emit excess of radiation in the form of alpha, beta and gamma rays.

For example, X-rays and gamma rays help in the use of medical diagnosis etc.

Therefore, we can conclude that the statements which best describe medical uses for radioactive isotopes are as follows.

• Radioactive isotopes are used to detect medical problems.

• Radioactive isotopes are used to treat some diseases.

• Radiation is used to kill cancer cells.
