DaughterA nucleus formed by the radioactive decay of a different (parent) nuclide.
Decay (radioactive)The change of one radioactive nuclide into a different nuclide by the spontaneous emission of alpha, beta, or gamma rays, or by electron capture.
DecontaminationThe removal of radioactive contaminants by cleaning and washing with chemicals.
DensityThe average number of people, families, or housing units on one unit of land. Density is also expressed as dwelling units per acre.
dermal uptakeThe transfer of a contaminant from air, water, or soil into or through the outer skin layer; considered an exposure route in an exposure assessment.

DisplacementDisplacement is the replacement of a U.S. worker by an H-1B worker in an essentially equivalent job and occurs within the period beginning 90 days before…
dissociationA chemical process by means of which a change in physical condition causes a molecule to split into simple groups of atoms, single atoms, or ions.
doseThe amount of medicine taken, or radiation given, at one time.
dose assessmentThe process by which uptake and dose of a toxic substance are identified and quantified.
dose equivalentAn absorbed dose that is adjusted or weighted to account for the potential of different radiations with the same damage.
