| (154) Survey--An evaluation of the radiological conditions
and potential hazards incident to the production, use, transfer, release,
disposal, and/or presence of radioactive materials or other sources
of radiation. When appropriate, this evaluation includes, but is not
limited to, physical examination of the location of radioactive material
and measurements or calculations of levels of radiation or concentrations
or quantities of radioactive material present.
(155) Telemetric position monitoring system--A data
transfer system that captures information from instrumentation and/or
measuring devices about the location and status of a transport vehicle
or package between the departure and destination locations.
(156) Termination--As applied to a license, a release
by the commission of the obligations and authorizations of the licensee
under the terms of the license. It does not relieve a person of duties
and responsibilities imposed by law.
(157) Tight-fitting facepiece--A respiratory inlet
covering that forms a complete seal with the face.
(158) Total effective dose equivalent (TEDE)--The sum
of the effective dose equivalent (for external exposures) and the
committed effective dose equivalent (for internal exposures).
(159) Total organ dose equivalent (TODE)--The sum of
the deep-dose equivalent and the committed dose equivalent to the
organ receiving the highest dose as described in §336.346(a)(6)
of this title (relating to Records of Individual Monitoring Results).
(160) Transuranic waste--For the purposes of this chapter,
wastes containing alpha emitting transuranic radionuclides with a
half-life greater than five years at concentrations greater than 100
nanocuries/gram.
(161) Trustworthiness and reliability--Characteristics
of an individual considered dependable in judgment, character, and
performance, such that unescorted access to category 1 or category
2 quantities of radioactive material by that individual does not constitute
an unreasonable risk to the public health and safety or security.
A determination of trustworthiness and reliability for this purpose
is based upon the results from a background investigation.
(162) Type A quantity (for packaging)--A quantity of
radioactive material, the aggregate radioactivity of which does not
exceed A 1 for special form radioactive material or A2 for normal
form radioactive material, where A1 and A2 are given in or shall be
determined by procedures in Appendix A to 10 Code of Federal Regulations
Part 71 as amended through September 28, 1995 (60 FR 50264) (Packaging
and Transportation of Radioactive Material).
(163) Type B quantity (for packaging)--A quantity of
radioactive material greater than a Type A quantity.
(164) Unescorted access--Solitary access to an aggregated
category 1 or category 2 quantity of radioactive material or the devices
that contain the material.
(165) Unrefined and unprocessed ore--Ore in its natural
form before any processing, such as grinding, roasting, beneficiating,
or refining.
(166) Unrestricted area--Any area that is not a restricted
area.
(167) User seal check (fit check)--An action conducted
by the respirator user to determine if the respirator is properly
seated to the face. Examples include negative pressure check, positive
pressure check, irritant smoke check, or isoamyl acetate check.
(168) Very high radiation area--An area, accessible
to individuals, in which radiation levels from radiation sources external
to the body could result in an individual receiving an absorbed dose
in excess of 500 rads (five grays) in one hour at one meter from a
source of radiation or one meter from any surface that the radiation
penetrates.
(169) Violation--An infringement of any provision of
the Texas Radiation Control Act (TRCA) or of any rule, order, or license
condition of the commission issued under the TRCA or this chapter.
(170) Waste--Low-level radioactive wastes containing
source, special nuclear, or byproduct material that are acceptable
for disposal in a land disposal facility. For the purposes of this
definition, low-level radioactive waste means radioactive waste not
classified as high-level radioactive waste, transuranic waste, spent
nuclear fuel, or byproduct material as defined in paragraph (20)(B)
- (E) of this section.
(171) Week--Seven consecutive days starting on Sunday.
(172) Weighting factor (wT )
for an organ or tissue (T)--The proportion of the risk of stochastic
effects resulting from irradiation of that organ or tissue to the
total risk of stochastic effects when the whole body is irradiated
uniformly. For calculating the effective dose equivalent, the values
of wT are:
Attached Graphic
(173) Whole body--For purposes of external exposure,
head, trunk including male gonads, arms above the elbow, or legs above
the knee.
(174) Worker--An individual engaged in activities under
a license issued by the commission and controlled by a licensee, but
does not include the licensee.
(175) Working level (WL)--Any combination of short-lived
radon daughters in one liter of air that will result in the ultimate
emission of 1.3 x 105 MeV of potential
alpha particle energy. The short-lived radon daughters are: for radon-222:
polonium-218, lead-214, bismuth-214, and polonium-214; and for radon-220:
polonium-216, lead-212, bismuth-212, and polonium-212.
(176) Working level month (WLM)--An exposure to one
working level for 170 hours (2,000 working hours per year divided
by 12 months per year is approximately equal to 170 hours per month).
(177) Year--The period of time beginning in January
used to determine compliance with the provisions of the rules in this
chapter. The licensee shall change the starting date of the year used
to determine compliance by the licensee provided that the change is
made at the beginning of the year and that no day is omitted or duplicated
in consecutive years.
