Which of the following statements is true? Question 11 options: Naturally occurring nuclear radiation is called background decay. You are exposed to nuclear radiation every day. Most of the nuclear radiation you are exposed to in the environment is man-made. All natural radiation is at a level low enough to be safe.

Explanation:

The human being has always been exposed to environmental radioactivity, but the atmosphere serves as a shield for most of it, and thus be protected.

The answer is: All natural radiation is at a level low enough to be safe.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
