2008 Site Environmental Report for Pantex Plant

2008 Site Environmental Report for Pantex Plant
non-ionizing radiation, such as microwaves or
visible, infrared or ultraviolet light.
Radioactive - The state of emitting radiation in
the form of waves (rays) or particles.
Radioactivity – The spontaneous emission of
radiation, generally alpha or beta particles, often
accompanied by gamma rays, from the nucleus of
an unstable isotope.
Randall soil series - Clay soils present in the
playa bottoms at Pantex Plant.
Raptor - Birds of prey including various species
of hawks, falcons, eagles, vultures, and owls.
Replicate analysis - A repeated operation
occurring within an analytical procedure, e.g., two
or more analyses for the same constituent in an
extract of a single sample. Replicate
environmental samples measure the overall
precision of the sampling or analytical methods,
while replicate analyses are identical analyses
carried out on the same sample multiple times.
They measure analytical laboratory precision only.
Resource Conservation and Recovery Act
(RCRA) - Federal statute which governs current
and planned hazardous waste management
activities.
Risk Reduction Rules - 30 TAC 335 Subchapter
S, outline three risk reduction levels to be
considered relative to the corrective measures
(DOE, 2002).
Risk Reduction Standard 1 /
Closure/remediation to background levels by
removing or decontaminating all waste,
waste residues, leachate, and contaminated
media to levels unaffected by waste
management activities.
Risk Reduction Standard 2 /
Closure/remediation to health-based
standards and criteria by removing,
containing, or decontaminating all waste,
waste residues, leachate, and contaminated
media to meet standards and criteria such that
any substantial present and future threats to
xx
human health and the environment are very
low.
Risk Reduction Standard 3 /
Closure/remediation with controls, which
entails removal, containment, or
decontamination of waste, waste residues,
leachate, and contaminated media to such
levels and in such a manner that any
substantial present or future threats to human
health and the environment are reduced to an
acceptable level, based on use.
Sanitization - The irreversible modification or
destruction of a component or part of a component
of a nuclear weapon, device, trainer or test
assembly, as necessary, to prevent revealing
classified or otherwise controlled information, as
required by the Atomic Energy Act of 1954, as
amended.
Saturated zone - The zone in which the voids in
the rock or soil are filled with water at a pressure
greater than atmospheric. The water table is the
top of the saturated zone in an unconfined aquifer.
Sedimentation - The process of deposition of
sediment, especially by mechanical means from a
state of suspension in air or water.
Seismic - Pertaining to any earth vibration,
especially an earthquake.
Sievert (Sv) S The Système International d'Unités
(SI units) unit of equivalent dose. One sievert is
equivalent to 100 rem.
Site - A geographic entity comprising leased or
owned land, buildings, and other structures
required to perform program activities.
Site (archeological) - Any area or location
occupied as a residence or used by humans for a
sufficient length of time to leave physical remains
or traces of occupancy. The sites are extremely
variable in size and may range from a single
hunting camp to an extensive land surface with
evidence of numerous settlements and activities.
The site(s) may consist of secondarily deposited
archeological remains.
