1.	Concerning magnification: a. It occurs because X-rays converge on the object b. Assuming a fixed focal spot position, it increases as the object is moved nearer to the film c. Assuming a fixed position of the object in relation to the focal spot, it increases as the focus-to-film distance (FFD) is increased d. If the object is in contact with the film, the magnification factor is 1 e. Minification of the image with film-screen radiography cannot occur
Answer» a. False. It occurs because X-rays are divergent from their source. b. False. This decreases magnification. c. True. The object-to-film distance would increase. d. True. In this case, there would be no magnification. e. True.
