What happens when lead foil comes into direct contact with X-ray film?
A. Intensifies the scatter radiation more than the primary radiation B. Decreases the contrast of the radiographic image C. Intensifies the primary radiation more than the scatter radiation D. Should not be used when gamma rays are emitted by the source of radiation
Primary radiation, as its name suggests is the main radiation that occurs when using an x ray machine. Scatter radiation is the secondary radiation that is produced as a result of the primary radiation. A third type of radiation exists called leakage radiation.
This is all the radiation that leaks out when the x ray machine is being used and scatters everywhere other than the focus point of the primary beam. When tin foil comes in direct contact with an x ray film it intensifies the primary radiation more than the scatter radiation.
