Answer:

Gamma rays can pass through a sheet of metal and hit the target.

Explanation:

Gamma rays are the most penetrating of the radiations, above alpha and beta rays. Gamma rays are highly energetic waves and are poor at ionizing other atoms or molecules. It would take over 1.3 feet of lead or almost 7 feet of concrete to absorb high levels of gamma rays.
