Which statements best describe medical uses for radioactive isotopes? check all that apply. radioactive isotopes are used to detect medical problems. high-energy gamma rays are injected into the body. radioactive isotopes are used to treat some diseases. radiation is used to kill cancer cells. radioactive isotopes are directed at tumors from outside the body.

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.

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.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
