SOLUTIONS TO EXERCISES, LESSON 3

1. Type of emulsion density of the tissues to be radiographed target-film distance characteristics of the exposing rays (para 3-2)

2. Film should be stored in a cool, dry place free from chemical contamination because high temperatures, moisture, and certain
chemicals will cause deterioration of the film's emulsion. (para 3-3)

3. The emulsion of the film is a thin coating of a special gelatin with minute particles of a silver compound. (para 3-3a(1))

4. An embossed dot (a raised spot) to identify right and left. This assists mounting radiographs in correct anatomical order. (para 3-3a(2))

5. A small size periapical film (Type O) measuring 7/8 x 1 3/8 inches. (para 3-3b(1)(a))

6. To intensify the effects of the exposing rays and lessen the exposure time. (para 3-3b(2)(a))

7. Magnify the x-ray beam, thus reducing exposure time. (para 3-3b(2)(b))

8. The entire dentition and surrounding bone structure. (para 3-3b(3))

9. Developing solution, water, and fixing solution. (para 3-8a)

10. Four to six minutes. (para 3-7)

11. cleanliness thermometer  timer film holders processing solutions sink illumination specific construction (para 3-6a-h)

12. To register the temperature of the solutions. (para 3-6c)

13. develop rinse fix wash dry (para 3-8b)

15. Movement of the patient, film, or tube during exposure. (para 3-12)

16. partial image. (para 3-13)

17. Exposure of film to light during storage. Leaving film unprotected in the x-ray room during operation of the x-ray machine. Use of film that has been exposed to heat or chemical fumes. Use of improperly mixed or contaminated developer. Defective safelight. (para 3-15)
