When duplicating radiographs, which side of the duplicating film is placed against the original radiograph?

When duplicating radiographs, the emulsion side of the duplicating film must be placed against the original radiograph. This is because the emulsion side contains the light-sensitive material that captures the image when exposed to light.

In the duplication process, the original radiograph emits light when exposed, and this light needs to interact with the emulsion side of the duplicating film to create a viable duplicate. By ensuring that the emulsion side is facing the original radiograph, the film is properly positioned to receive the image.

Using the nonemulsion side or other areas of the film would not allow for image transfer, as those sides do not contain the necessary light-sensitive materials to capture the radiographic detail. This understanding is crucial for anyone involved in producing accurate duplicates of radiographs for patient records or referral purposes.
