Committed Effective Dose Equivalent: As defined in Title 10, Section 20.1003, of the Code of Federal Regulations (10 CFR 20.1003), the CEDE (HE,50) is the sum of the products of the committed dose equivalents for each of the body organs or tissues that are irradiated multiplied by the weighting factors (WT) applicable to each of those organs or tissues (HE,50 = ΣWTHT.50).
Deep Dose Equivalent: The external whole-body exposure dose equivalent at a tissue depth of 1 cm (1000 mg/cm2). For further information, see Measuring Radiation.
Lens Dose Equivalent: The external exposure dose equivalent to the lens of the eye at a tissue depth of 0.3 centimeters (300 mg/cm2).
Shallow Dose Equivalent: The external exposure dose equivalent to the skin or an extremity at a tissue depth of 0.007 centimeters (7 mg/cm2) averaged over an area of 1 square centimeter ME diferentiates this dose as the SDE at the extremity with the maximum dose (max extremity)
Shallow Dose Equivalent: The external exposure dose equivalent to the skin or an extremity at a tissue depth of 0.007 centimeters (7 mg/cm2) averaged over an area of 1 square centimeter WB diferentiates this dose as the SDE across the whole body
