• C. Not sure
• D. Both

Answer: (B)

Fogging of dental film occurs when the emulsion is exposed to light that passes through the safelight. Dental film is designed to be processed in a darkroom with a safelight that uses a red filter because red light has a long wavelength and does not significantly expose the film. A blue room would emit blue light, which can reach the film and cause unwanted exposure, leading to fog and loss of contrast and detail in the radiograph. That’s why the statement is not correct—the proper practice is to develop conventional x-rays in a darkroom with a red safelight, not a blue room.
