What should be avoided when handling films to prevent artefacts?

When handling films, using wet hands is crucial to avoid artefacts because moisture can lead to water spots, streaks, or other marks on the film. Wet hands can transfer moisture onto the film surface, creating unwanted patterns that interfere with the clarity and quality of the radiographic image. This is particularly important because any artefacts can obscure the diagnostic information that the radiographs need to convey. Maintaining dry hands ensures that the film remains clean and free from contaminants that could compromise the imaging process.

While working in a bright area can impact the exposure of certain films and wearing gloves or using clean tools are generally good practice to maintain cleanliness, they do not directly relate to the specific issue of transferring moisture to the film that wet hands do. Being mindful about keeping hands dry is one of the key practices to ensure the integrity of the films during handling.
