Deep Dose Equivalent, Effective Dose Equivalent, Lens of the Eye Dose Equivalent, and

Total Effective Dose Equivalent) [10 CFR 835.2]

166.

DRUG CERTIFICATION. A written assurance signed by an individual with known past

illegal drug involvement, as a condition for obtaining or retaining a DOE access

authorization, stating that the individual will refrain from using or being involved with

illegal drugs while employed in a position requiring DOE access authorization (security

clearance). [10 CFR 707.4]

EDUCATION. The successful completion of the requirements established by an

167.

accredited educational institution. [DOE O 5480.20A] [EH62dd1]

168.

EFFECTIVE DOSE EQUIVALENT (EDE). The dose equivalent from both external and

internal irradiation defined by Στ, Wτ, Hτ where Hτ is the dose equivalent in tissue T and

Wτ is the weighing factor representing the ratio of the risk arising from irradiation of

tissue T to the total risk when the whole body is irradiated uniformly. The effective dose

equivalent is expressed in units of rem. (See Committed Dose Equivalent, Committed

Effective Dose Equivalent, Cumulative Total Effective Dose Equivalent, Deep Dose

Equivalent, Dose Equivalent, Lens of the Eye Dose Equivalent, and Total Effective Dose

Equivalent) [DOE O 6430.1A]

169.

EFFECTIVE DOSE EQUIVALENT (HE). The summation of the products of the dose

equivalent received by specified tissues of the body (Hτ) and the appropriate weighting

factor (wτ)-that is, HE = ΣwτHτ. It includes the dose from radiation sources internal and/or

external to the body. For purposes of compliance with 10 CFR 835, deep dose equivalent

to the whole body may be used as effective dose equivalent for external exposures. The

effective dose equivalent is expressed in units of rem (or sievert). (See Committed Dose

Equivalent, Committed Effective Dose Equivalent, Cumulative Total Effective Dose

Equivalent, Deep Dose Equivalent, Dose Equivalent, Lens of the Eye Dose Equivalent,

and Total Effective Dose Equivalent) [10 CFR 835.2]

EIGHT (8)-HOUR TIME-WEIGHTED AVERAGE (TWA) EXPOSURE LIMIT. The

170.

time-weighted average concentration in the employee's breathing zone which shall not be

exceeded in any 8-hour work shift of a 40-hour workweek. [DOE O 5480.10A (Draft)]

ELECTRIC SHOCK. Physical stimulation that occurs when electrical current passes

171.

through the body. [IEEE 1584-2002]

172.

ELECTRICAL HAZARD. A dangerous condition such that contact or equipment failure

can result in electric shock, arc flash burn, thermal burn, or blast. [NFPA 70E]
