What is the standard length of the power cord for the exposure switch on a portable x-ray machine?

The standard length of the power cord for the exposure switch on a portable x-ray machine is indeed 72 inches. This length is designed to provide adequate distance between the operator and the radiation source during the exposure, enhancing safety for the operator. The 72-inch length helps ensure that the person operating the machine can maintain a safe distance, thereby reducing their exposure to x-ray radiation while still being able to control the operation of the machine effectively.

This distance is established based on safety protocols in radiological practices and aligns with guidelines from organizations concerned with radiation safety. Using a cord of this length facilitates a balance between accessibility to the machine and adequate safety measures to protect the operator from potential radiation exposure.
