Gonadal Shielding

A lead apron should be draped over the patient to shield the patient's body.

Failure of the Timer Device to Terminate an X-ray Exposure

All medical x-ray devices are manufactured such that removing pressure from the x-ray activation switch will cause termination of the x-ray production. In the event that the automatic timer on an x-ray machine does not halt the exposure after the preset time interval, immediately remove pressure from the x-ray activation switch. This will halt the x-ray production. In addition, immediately turn off the power to the x-ray machine, and post a sign stating that the machine is malfunctioning, and may not be used.

Notify your supervisor, clinical engineering and Radiation Safety. Discontinue use of the machine until has been evaluated by a qualified expert or service engineer.
