Vital Program

DOE-HDBK-1188-2006

one hour at 1 meter from a radiation source or from any surface that the radiation penetrates.

[10 CFR 835.2]

660.

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

O 5480.7A] [EH62dd1]

661.

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

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

662.

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]

663.

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]

664.

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]

665.

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]

666. 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] [DOE G

450.4-1B]

667. WORKER. A person who performs work for or on behalf of DOE, including a DOE employee,

an independent contractor, a DOE contractor or subcontractor employee, or any other person

who performs work at a DOE facility. [10 CFR 850.3]

668. WORK CONTROL DOCUMENT. A proceduralized document used by facility personnel to

perform activities such as maintenance, inspections, testing, or other work. [DOE G 433.1-1]
