NAC459.604. X-ray and electron therapy installations: Selections of radiation type, energy, and stationary or moving beam.

     1. In equipment capable of both X-ray therapy and electron therapy:

     (a) Irradiation must not be possible until a selection of radiation types, either X rays or electrons, has been made at the treatment control panel; and

     (b) The radiation type selected must be displayed at the treatment control panel before and during irradiation.

     2. In equipment capable of generating radiation beams of different energies:

     (a) Irradiation must not be possible until a selection of energy has been made at the treatment control panel; and

     (b) The energy and type of irradiation selected, either X rays or electrons, must be displayed at the treatment control panel before and during irradiation.

     3. In equipment capable of both stationary-beam therapy and moving-beam therapy:

     (a) Irradiation must not be possible until a selection of stationary-beam therapy or moving-beam therapy has been made at the treatment control panel;

     (b) Moving-beam therapy must be controlled so that the required dose monitor units per degree of rotation is obtained; and

     (c) The mode of operation must be displayed at the treatment control panel.
