SECTION 252:410-11-62. Selection of energy  


Latest version.
  •   Systems of 1 MeV or more which are capable of generating radiation beams of different energies must meet the following requirements:
    (1)   Irradiation shall not be possible until a selection of energy has been made at the control panel;
    (2)   An interlock system must prevent irradiation if any selected operations carried out in the treatment room do not agree with the selected operations carried out at the control panel;
    (3)   The nominal energy value selected is displayed at the control panel before and during irradiation; and
    (4)   For post-1989 systems, the interlock system will terminate irradiation if the energy of the electrons striking the x-ray target or electron window deviates by more than 20 percent from the selected nominal energy.
