Wurzburg tube CORRECT ANSWER: A Roentgen was working with a low-vacuum tube known as a Crookes tube. REFFERENCE: p.2 3. Which of the following terms could be defined as the instantaneous production of light only during an interaction between a type of energy and some element or compound? a. Phosphorescence b. Afterglow c. Glowing d. Fluorescence CORRECT ANSWER: D Fluorescence is the instantaneous emission of light from a material due to the interaction with some type of energy. REFFERENCE: p.2 4.

Roentgen rays. c. Z-rays. d. none of the above. ANS: B X-rays were at one time called Roentgen rays. REFFERENCE: p.4 9. Erythema, an early sign of biologic damage due to x-ray exposure, is: a. reddening of the skin. b. a malignant tumor. c. a chromosomal change. d. one of the most serious effects of x-ray exposure. ANS: A Erythema is reddening and burning of the skin, an early and less serious effect of exposure to large doses of x-radiation. REFFERENCE: p.5 10. X-rays have which of the following properties? a. Electrical b. Magnetic c. Chemical d. A and B e. A and C CORRECT ANSWER: D X-rays, a type of electromagnetic radiation, have both electrical and magnetic properties. REFFERENCE: p.5 11. The distance between two successive crests of a sine wave is known as: a. an angstrom. b. frequency. c. the Greek letter nu. d. wavelength CORRECT ANSWER: D The distance between two successive crests or troughs of a sine wave is the measure of its wavelength. REFFERENCE: p.6 12. X-rays used in radiography have wavelengths that are measured in: a. angstroms. b. millimeters. c. centimeters. d. hertz. CORRECT ANSWER: A X-rays in the range used in radiography have wavelengths that are so short that they are measured in angstroms. REFFERENCE: p.6 13. The frequency of a wave is the number of waves passing a given point per given unit of time. Frequency is measured in: a. angstroms. b. hertz. c. inches. d. eV.
