| (vi) oil and gas NORM waste.
(C) When used in this section, the references to 10
CFR sections mean those CFR sections as they existed on September
1, 1999, as required by Texas Health and Safety Code, §401.005.
(90) Lung class--See "Class."
(91) Member of the public--Any individual except when
that individual is receiving an occupational dose.
(92) Minor--An individual less than 18 years of age.
(93) Mixed waste--A combination of hazardous waste,
as defined in §335.1 of this title (relating to Definitions)
and low-level radioactive waste. The term includes compact waste and
federal facility waste containing hazardous waste.
(94) Mobile device--A piece of equipment containing
licensed radioactive material that is either mounted on wheels or
casters, or otherwise equipped for moving without a need for disassembly
or dismounting; or designed to be hand carried. Mobile devices do
not include stationary equipment installed in a fixed location.
(95) Monitoring--The measurement of radiation levels,
radioactive material concentrations, surface area activities, or quantities
of radioactive material and the use of the results of these measurements
to evaluate potential exposures and doses. For purposes of the rules
in this chapter, "radiation monitoring" and "radiation
protection monitoring" are equivalent terms.
(96) Movement control center--An operations center
that is remote from transport activity and that maintains position
information on the movement of radioactive material, receives reports
of attempted attacks or thefts, provides a means for reporting these
and other problems to appropriate agencies and can request and coordinate
appropriate aid.
(97) Nationally tracked source--A sealed source containing
a quantity equal to or greater than category 1 or category levels
of any radioactive material listed in §336.351 of this title
(relating to Reports of Transactions Involving Nationally Tracked
Sources). In this context a sealed source is defined as radioactive
material that is sealed in a capsule or closely bonded, in a solid
form and which is not exempt from regulatory control. It does not
mean material encapsulated solely for disposal, or nuclear material
contained in any fuel assembly, subassembly, fuel rod, or fuel pellet.
Category 1 nationally tracked sources are those containing radioactive
material at a quantity equal to or greater than the category 1 threshold.
Category 2 nationally tracked sources are those containing radioactive
material at a quantity equal to or greater than the category 2 threshold
but less than the category 1 threshold.
(98) Naturally occurring or accelerator-produced radioactive
material (NARM)--Any NARM except source material or special nuclear
material.
(99) Naturally occurring radioactive material (NORM)
waste--Solid, liquid, or gaseous material or combination of materials,
excluding source material, special nuclear material, and byproduct
material, that:
(A) in its natural physical state spontaneously emits
radiation;
(B) is discarded or unwanted; and
(C) is not exempt under rules of the Texas Department
of State Health Services adopted under Texas Health and Safety Code, §401.106.
(100) Near-surface disposal facility--A land disposal
facility in which low-level radioactive waste is disposed of in or
within the upper 30 meters of the earth's surface.
(101) Negative pressure respirator (tight fitting)--A
respirator in which the air pressure inside the facepiece is negative
during inhalation with respect to the ambient air pressure outside
the respirator.
(102) No-later-than arrival time--The date and time
that the shipping licensee and receiving licensee have established
as the time an investigation will be initiated if the shipment has
not arrived at the receiving facility. The no-later-than arrival time
may not be more than six hours after the estimated arrival time for
shipments of category 2 quantities of radioactive material.
(103) Nonstochastic effect--A health effect, the severity
of which varies with the dose and for which a threshold is believed
to exist. Radiation-induced cataract formation is an example of a
nonstochastic effect. For purposes of the rules in this chapter, "deterministic
effect" is an equivalent term.
(104) Occupational dose--The dose received by an individual
in the course of employment in which the individual's assigned duties
involve exposure to radiation and/or to radioactive material from
licensed and unlicensed sources of radiation, whether in the possession
of the licensee or other person. Occupational dose does not include
dose received from background radiation, as a patient from medical
practices, from voluntary participation in medical research programs,
or as a member of the public.
(105) Oil and gas naturally occurring radioactive material
(NORM) waste--NORM waste that constitutes, is contained in, or has
contaminated oil and gas waste as that term is defined in the Texas
Natural Resources Code, §91.1011.
(106) On-site--The same or geographically contiguous
property that may be divided by public or private rights-of-way, provided
the entrance and exit between the properties is at a cross-roads intersection,
and access is by crossing, as opposed to going along, the right-of-way.
Noncontiguous properties owned by the same person but connected by
a right-of-way that the property owner controls and to which the public
does not have access, is also considered on-site property.
(107) Particle accelerator--Any machine capable of
accelerating electrons, protons, deuterons, or other charged particles
in a vacuum and discharging the resultant particulate or other associated
radiation at energies usually in excess of 1 million electron volts
(MeV).
(108) Party state--Any state that has become a party
to the compact in accordance with Article VII of the Texas Low-Level
Radioactive Waste Disposal Compact, established under Texas Health
and Safety Code, §403.006.
(109) Perpetual care account--The Environmental Radiation
and Perpetual Care Account as defined in this section.
(110) Personnel monitoring equipment--See "Individual
monitoring devices."
(111) Planned special exposure--An infrequent exposure
to radiation, separate from and in addition to the annual occupational
dose limits.
(112) Positive pressure respirator--A respirator in
which the pressure inside the respiratory inlet covering exceeds the
ambient air pressure outside the respirator.
(113) Powered air-purifying respirator (PAPR)--An air-purifying
respirator that uses a blower to force the ambient air through air-purifying
elements to the inlet covering.
(114) Pressure demand respirator--A positive pressure
atmosphere-supplying respirator that admits breathing air to the facepiece
when the positive pressure is reduced inside the facepiece by inhalation.
(115) Principal activities--Activities authorized by
the license which are essential to achieving the purpose(s) for which
the license is issued or amended. Storage during which no licensed
material is accessed for use or disposal and activities incidental
to decontamination or decommissioning are not principal activities.
(116) Public dose--The dose received by a member of
the public from exposure to radiation and/or radioactive material
released by a licensee, or to any other source of radiation under
the control of the licensee. It does not include occupational dose
or doses received from background radiation, as a patient from medical
practices, or from voluntary participation in medical research programs.
(117) Qualitative fit test (QLFT)--A pass/fail test
to assess the adequacy of respirator fit that relies on the individual's
response to the test agent.
(118) Quality factor (Q)--The modifying factor listed
in Table I or II of §336.3(c) or (d) of this title (relating
to Units of Radiation Exposure and Dose) that is used to derive dose
equivalent from absorbed dose.
(119) Quantitative fit test (QNFT)--An assessment of
the adequacy of respirator fit by numerically measuring the amount
of leakage into the respirator.
(120) Quarter (Calendar quarter)--A period of time
equal to one-fourth of the year observed by the licensee (approximately
13 consecutive weeks), providing that the beginning of the first quarter
in a year coincides with the starting date of the year and that no
day is omitted or duplicated in consecutive quarters.
(121) Rad--See §336.3 of this title (relating
to Units of Radiation Exposure and Dose).
