Sample questions
-
1.Which of the following correctly describes the production methods of X-rays and γ-rays?
- A.X-rays are produced by fast electrons striking a low atomic weight metal; γ-rays are produced by chemical reactions.
- B.X-rays are produced when fast moving electrons strike a metal of high atomic weight and high melting point; γ-rays are produced from nuclei of substances either by artificial or natural disintegrations.
- C.X-rays are produced by nuclear fission; γ-rays are produced by electron bombardment of gases.
- D.X-rays and γ-rays are both produced by heating metals to extremely high temperatures.
