Which of the following is considered an unacceptable use of radiation?

The use of fluoroscopy for fitting shoes is considered an unacceptable application of radiation. Fluoroscopy involves the use of X-rays to produce real-time images of what is happening inside the body. This method exposes the patient to radiation, which can pose significant health risks, especially when used unnecessarily.

In the context of fitting shoes, utilizing fluoroscopy for such a non-essential purpose can lead to radiation exposure without any medical justification, increasing the potential for harm rather than providing a necessary diagnostic benefit.

In contrast, osteopathy and chiropody are established medical practices where the use of radiation may be justified under appropriate clinical circumstances, such as diagnosing and treating conditions. Therefore, while both of these practices can involve diagnostic imaging, they are conducted with a focus on patient health and safety, making them acceptable within the context of medical care. Hence, the concern with fluoroscopy for shoe fitting is its inappropriate application of radiation in a situation where the risks outweigh the benefits.
