of the licensee/registrant or other person. Occupational dose does
not include dose received from background radiation, from any medical

administered radioactive material and released in accordance with
this chapter, from voluntary participation in medical research programs,
or as a member of the public.

radiation at energies usually in excess of 1 million electron volts
(MeV).
(82) Person--Any individual, corporation, partnership,
firm, association, trust, estate, public or private institution, group,
agency, local government, any other state or political subdivision
or agency thereof, or any other legal entity, and any legal successor,
representative, agent, or agency of the foregoing, other than NRC,
and other than federal government agencies licensed or exempted by
NRC.
(83) Personnel monitoring equipment (See definition
for individual monitoring devices.)
(84) Pharmacist--An individual licensed by the Texas
State Board of Pharmacy to compound and dispense drugs, prescriptions,
and poisons.
(85) Physician--An individual licensed by the Texas
Medical Board.
(86) Portable device--A piece of equipment containing
licensed radioactive material that is designed by the manufacturer
to be hand carried during use.
(87) Positron emission tomography (PET) radionuclide
production facility--A facility operating a cyclotron or accelerator
for the purpose of producing PET radionuclides.
(88) Principal activities--Activities authorized by
the license that are essential to achieving the purpose(s) for which
the license was 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.
(89) Public dose--The dose received by a member of
the public from exposure to sources of radiation released by a licensee,
or to any other source of radiation under the control of a licensee/registrant.
It does not include occupational dose or doses received from background
radiation, from any medical administration the individual has received,
from exposure to individuals administered radioactive material and
released in accordance with this chapter, or from voluntary participation
in medical research programs.
(90) Quality factor (Q)--The modifying factor listed
in subsection (n)(1) and (2) of this section that is used to derive
dose equivalent from absorbed dose.
(91) 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.
(92) Rad--The special unit of absorbed dose. One rad
is equal to an absorbed dose of 100 ergs per gram (erg/g) or 0.01
J/kg (0.01 Gy).
(93) Radiation--One or more of the following:
(A) gamma and x rays; alpha and beta particles and
other atomic or nuclear particles or rays;
(B) emission of radiation from any electronic device
to such energy density levels as to reasonably cause bodily harm;
or
(C) sonic, ultrasonic, or infrasonic waves from any
electronic device or resulting from the operation of an electronic
circuit in an electronic device in the energy range to reasonably
cause detectable bodily harm.
(94) Radiation area--Any area, accessible to individuals,
in which radiation levels could result in an individual receiving
a dose equivalent in excess of 0.005 rem (0.05 mSv) in one hour at
30 cm from the source of radiation or from any surface that the radiation
penetrates.
(95) Radiation machine--Any device capable of producing
ionizing radiation except those devices with radioactive material
as the only source of radiation.
(96) Radiation safety officer (RSO)--An individual
who has a knowledge of and the authority and responsibility to apply
appropriate radiation protection rules, standards, and practices,
who must be specifically authorized on a radioactive material license,
and who is the primary contact with the agency. Specific training
and responsibilities for an RSO are listed in §289.252 of this
title, §289.253 of this title (relating to Radiation Safety Requirements
for Well Logging Service Operations and Tracer Studies), §289.255
of this title (relating to Radiation Safety Requirements and Licensing
and Registration Procedures for Industrial Radiography), and §289.256
of this title (relating to Medical and Veterinary Use of Radioactive

(97) Radioactive material--Any material (solid, liquid,
or gas) that emits radiation spontaneously.
(98) Radioactive waste--For purposes of this chapter,
this term is equivalent to LLRW.

expressed as dose equivalent. The dose equivalent in rem is equal
to the absorbed dose in rad multiplied by the quality factor (1 rem

is defined as:
(A) theoretical analysis, exploration, or experimentation;
or
(B) the extension of investigative findings and theories
