VERIFICATION (PROCEDURES). Independent determination that a procedure is

technically correct and consistent with the procedures standard (Writer's Guide).

[EH62dd1]

VERY HIGH RADIATION AREA. Any area accessible to individuals in which

656.

radiation levels could result in an individual receiving an absorbed dose in excess of 500

rads (5 grays) in one hour at 1 meter from a radiation source or from any surface that the

radiation penetrates. [10 CFR 835.2]

657.

VITAL PROGRAM. A DOE program so defined by the Program Secretarial Officers.

[DOE O 5480.7A] [EH62dd1]

658.

VOLATILE CHEMICALS. Chemicals that can be readily vaporized at a relatively low

temperature. [DOE O 5480.EIA] [EH62dd1]

659.

VOLTAGE (nominal): A nominal value assigned to a circuit or system for the purpose

of conveniently designating its voltage class (as 120/240 V, 480Y/277 V, 600 V). The

actual voltage at which a circuit operates can vary from the nominal within a range that

permits satisfactory operation of equipment. [IEEE 1584-2002] [NFPA 70E]

660.

VOLTAGE. The effective (rms) potential difference between any two conductors or

between a conductor and ground. Voltages are expressed in nominal values unless

otherwise indicated. The nominal voltage of a system or circuit is the value assigned to a

system or circuit of a given voltage class for the purpose of convenient designation. The

operating voltage of the system may vary above or below this value. [DOE-HDBK-1092-

2004]

661.

WEIGHTING FACTOR (WT). The fraction of the overall health risk, resulting from

uniform, whole body irradiation, attributable to specific tissue (T). The dose equivalent to

tissue, (HT ) is multiplied by the appropriate weighting factor to obtain the effective dose

equivalent contribution from that tissue. [10 CFR 835.2]

662.

WHOLE BODY For the purposes of external exposure, head, trunk (including male

gonads), arms above and including the elbow, or legs above and including the knee. [10

CFR 835.2]

663. WORK. Process of performing a defined task or activity, for example, research and

development, operations, maintenance and repair, administration, software development

and use, inspection, safeguards and security, data collection, and analysis. [EH62add1]
