The exposure switch on a portable x-ray machine must have a cord that is at least how many feet long?

The requirement for the exposure switch on a portable x-ray machine to have a cord that is at least six feet long is based on safety regulations designed to protect the operator from radiation exposure. A longer cord allows the operator to stand a safe distance away from the x-ray tube while still being able to initiate the exposure. This distance minimizes their risk of receiving unnecessary radiation during the procedure.

In addition, having a six-foot cord ensures that the operator can maintain appropriate visibility and control over the patient and the x-ray process, contributing to better overall safety and effectiveness in operating the equipment. The regulation emphasizes the importance of both safety and operational functionality in diagnostic imaging practices.
