Chapter 19 - LICENSES AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS
Section 180-19-012 - CONTROL OF SOURCE MOVEMENT
Current through March 20, 2024
012.01 KEY. The mechanism that moves the sources of a panoramic irradiator must require a key to actuate. Actuation of the mechanism must cause an audible signal to indicate the sources are leaving the shielded position. Only one key may be in use at any time, and only operators or facility management may possess it. The key must be attached to a portable radiation survey meter by a chain or cable. The lock for source control must be designed so the key may not be removed if the sources are in an unshielded position. The door to the radiation room must require the same key.
012.02 POSITION DETECTOR. The console of a panoramic irradiator must have a source position indicator that indicates when the sources are in the fully shielded position, in transit, and exposed.
012.03 CONTROL CONSOLE. The control console of a panoramic irradiator must have a control that promptly returns the sources to the shielded position.
012.04 CONTROL MARKING. Each control for a panoramic irradiator must be clearly marked as to its function.
