A. Overcoat
B. Emulsion
C. Adhesive Layer.
D. Base
Emulsion
A type of film which is not sensitive to light and is not commonly used because of increased patient dose.

D. None of the above
screen film
Which of the following statement is true about Handling and Storage of Film:
A. Film is sensitive to heat and O humidity as it causes loss of
contrast.

D. None of the above
Both A and B
A rectangle or square plastic or metallic container used to hold x-ray films (exposed or unexposed) and intensifying screens in close and uniform contact with one another.
Radiographic Cassette
The use of this specific screen results in a lower patient dose, less thermal stress on the x-ray tube, and reduces shielding for x-ray rooms.
