Which one of the following describes an unacceptable method of storage of X-ray film packets in the dental workplace?

Storing X-ray film packets in a cupboard next to the X-ray machine is considered an unacceptable method of storage primarily due to the risk of exposure to radiation. X-ray film is sensitive to radiation and should be kept in a controlled environment to prevent any degradation of the film quality. Storing it too close to the source of radiation can lead to fogging, compromising the diagnostic effectiveness of the images produced.

In contrast, placing film packets in a stock room with filling materials, in a processing room drawer, or in a surgery drawer with instruments generally does not expose them to radiation and can be suitable methods of storage if those areas are maintained in a suitable condition. Each of these alternatives ensures that the films are kept away from direct exposure to harmful elements that could affect their integrity.
