as used in the rules of this chapter means the holder of a "specific
license."
(85) Licensing state--Any state with rules equivalent
to the Suggested State Regulations for Control of Radiation relating
to, and having an effective program for, the regulatory control of
naturally occurring or accelerator-produced radioactive material (NARM)
and which has been designated as such by the Conference of Radiation
Control Program Directors, Inc.
(86) Local law enforcement agency (LLEA)--A public
or private organization that has been approved by a federal, state,
or local government to carry firearms; make arrests; and is authorized

where the licensed category 1 or category 2 quantity of radioactive
material is used, stored, or transported.
(87) Loose-fitting facepiece--A respiratory inlet covering
that is designed to form a partial seal with the face.
(88) Lost or missing licensed radioactive material--Licensed
material whose location is unknown. This definition includes material
that has been shipped but has not reached its planned destination
and whose location cannot be readily traced in the transportation
system.
(89) Low-level radioactive waste--
(A) Except as provided by subparagraph (B) of this
paragraph, low-level radioactive waste means radioactive material
that:
(i) is discarded or unwanted and is not exempt by a
Texas Department of State Health Services rule adopted under the Texas
Health and Safety Code, §401.106;
(ii) is waste, as that term is defined by 10 Code of
Federal Regulations (CFR) §61.2; and
(iii) is subject to:
(I) concentration limits established under this chapter;
and
(II) disposal criteria established under this chapter.
(B) Low-level radioactive waste does not include:
(i) high-level radioactive waste defined by 10 CFR §60.2;
(ii) spent nuclear fuel as defined by 10 CFR §72.3;
(iii) transuranic waste as defined in this section;
(iv) byproduct material as defined by paragraph (20)(B)
- (E) of this section;
(v) naturally occurring radioactive material (NORM)
waste; or
(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.
