Option 2 : Excessive safelight exposure
Detailed Solution
Download Solution PDFCorrect Answer: Excessive safelight exposure
Rationale:
- Excessive safelight exposure can cause increased fog on the X-ray film. Safelights are designed to provide illumination in darkrooms without exposing the film to wavelengths of light that would cause it to fog. However, if the safelight is too bright, too close to the work area, or if the filter is incorrect or damaged, it can contribute to film fogging.
- Fog on X-ray film reduces image contrast and can obscure important diagnostic information. Therefore, it is crucial to ensure that safelights are properly installed and maintained to minimize any risk of fogging.
Explanation of Other Options:
Overdevelopment
- Rationale: Overdevelopment refers to leaving the film in the developer solution for too long or using a developer solution that is too strong. While overdevelopment can increase the density of the film, it is not a primary cause of film fogging. It generally leads to increased contrast rather than a uniform fog.
Low temperature in the developer
- Rationale: Low temperature in the developer solution slows down the development process. This can result in underdeveloped films with lower density and contrast, but it does not typically cause increased fog on the film.
Proper film storage
- Rationale: Proper film storage involves keeping the film in a cool, dry place away from radiation, chemicals, and excessive light. Proper storage practices help to prevent fogging and other forms of damage to the film, ensuring that it remains in good condition until it is used.
Conclusion:
- Among the given options, excessive safelight exposure is the correct answer as it is a common cause of increased fog on X-ray film. It is important to monitor and control safelight conditions in darkrooms to maintain the quality and clarity of the X-ray images.
