high voltage means the set of nominal voltage levels that are used in power systems for bulk transmission of electricity in the range of 44kV<Un 220 kV. [ SANS 1019];
High voltage bus means the electrical circuit, including the coupling system for charging the REESS that operates on high voltage.
X-ray high-voltage generator means a device which transforms electrical energy from the potential supplied by the x-ray control to the tube operating potential. The device may also include means for transforming alternating current to direct current, filament transformers for the x-ray tube(s), high-voltage switches, electrical protective devices, and other appropriate elements.
Energy Use Intensity (EUI) means the kBTUs (1,000 British Thermal Units) used per square foot of gross floor area.
Very high radiation area means an area, accessible to individuals, in which radiation levels from radiation sources external to the body could result in an individual receiving an absorbed dose in excess of 5 Gy (500 rad) in one hour at one meter from a source of radiation or one meter from any surface that the radiation penetrates.
