The following text was automatically extracted from the image on this page using optical character recognition software:
(B) manufacturer's name, model number and serial
number of the remote afterloader unit;
(C) notations accounting for all sealed sources before
the licensee departs from a facility;
(D) notations indicating the operability of each entrance
door electrical interlock, radiation monitors, sealed source exposure
indicator lights, viewing and intercom system, applicators and sealed
source transfer tubes, and sealed source positioning accuracy; and
(E) the signature of the individual who performed the
check.
(qqq) Radiation surveys.
(1) In addition to the survey requirements of 289.202(p)
of this title, a person licensed to use sealed sources in this section shall
make surveys to ensure that the maximum radiation levels and average
radiation levels, from the surface of the main sealed source safe with
the sealed source(s) in the shielded position, do not exceed the levels
stated in the Sealed Source and Device Registry.
(2) The licensee shall make the survey required by para-
graph (1) of this subsection at installation of a new sealed source
and following repairs to the sealed source(s) shielding, the sealed
source(s) driving unit, or other electronic or mechanical component
that could expose the sealed source, reduce the shielding around the
sealed source(s), or compromise the radiation safety of the unit or the
sealed source(s).
(3) The licensee shall maintain a record for inspection by
the agency, in accordance with subsection (www) of this section, of
the radiation surveys required by paragraph (1) of this subsection. The
record shall include:
(A) date of the measurements;
(B) manufacturer's name, model number and serial
number of the treatment unit, sealed source, and instrument used to
measure radiation levels;
(C) each dose rate measured around the sealed source
while the unit is in the "off" position and the average of all measure-
ments; and
(D) the signature of the individual who performed the
test.
(rrr) Five-year inspection for teletherapy and gamma stereo-
tactic radiosurgery units.
(1) The licensee shall have each teletherapy unit and
gamma stereotactic radiosurgery unit fully inspected and serviced
during sealed source replacement or at intervals not to exceed five
years, whichever comes first, to assure proper functioning of the sealed
source exposure mechanism.
(2) This inspection and servicing may only be performed
by persons specifically licensed to do so by the agency, the NRC, an
agreement state, or licensing state.
(3) The licensee shall maintain a record of the inspection
and servicing in accordance with subsection (www) of this section for
inspection by the agency. The record shall include the following:
(A) date of inspection;
(B) manufacturer's name and model and serial number
of both the treatment unit and the sealed source;
(C) a list of components inspected and serviced, and the
type of service; and(D) the radioactive material license number and the sig-
nature of the individual performing the inspection.
(sss) Therapy-related computer systems. The licensee shall
perform acceptance testing on the treatment planning system of ther-
apy-related computer systems in accordance with published protocols
accepted by nationally recognized bodies. At a minimum, the accep-
tance testing shall include, as applicable, verification of the following:
(1) the sealed source-specific input parameters required by
the dose calculation algorithm;
(2) the accuracy of dose, dwell time, and treatment time
calculations at representative points;
(3) the accuracy of isodose plots and graphic displays;
(4) the accuracy of the software used to determine sealed
source positions from radiographic images; and
(5) the accuracy of electronic transfer of the treatment de-
livery parameters to the treatment delivery unit from the treatment plan-
ning system.
(ttt) Training for use of remote afterloader units, teletherapy
units, and gamma stereotactic radiosurgery units. Except as provided
in subsection (1) of this section, the licensee shall require an authorized
user of a sealed source for a use authorized in subsection (ddd) of this
section to be a physician who:
(1) is certified by a medical specialty board whose certifi-
cation process has been recognized by the agency, the NRC, an agree-
ment state, or licensing state and who meets the requirements of para-
graphs (2)(D) and (3) of this subsection. (The names of board certifi-
cations that have been recognized by the agency, the NRC, an agree-
ment state, or licensing state will be posted on the agency's web page,
www.dshs.state.tx.us/radiation). To have its certification recognized, a
specialty board shall require all candidates for certification to:
(A) successfully complete a minimum of three years of
residency training in a radiation therapy program approved by the Res-
idency Review Committee of the Accreditation Council for Graduate
Medical Education, the Royal College of Physicians and Surgeons of
Canada, or the Committee on Post-Graduate Training of the American
Osteopathic Association; and
(B) pass an examination, administered by diplomates of
the specialty board, that assesses knowledge and competence in radi-
ation safety, radionuclide handling, treatment planning, quality assur-
ance, and clinical use of stereotactic radiosurgery, remote afterloaders
and external beam therapy; or
(2) has completed a structured educational program in ba-
sic radionuclide handling techniques applicable to the use of a sealed
source in a therapeutic medical unit including:
(A) 200 hours of classroom and laboratory training in
the following areas:
(i) radiation physics and instrumentation;
(ii) radiation protection;
(iii) mathematics pertaining to the use and measure-
ment of radioactivity; and
(iv) radiation biology; and
(B) 500 hours of work experience, under the supervi-
sion of an authorized user who meets the requirements of this subsec-
tion at a medical institution involving the following:32 TexReg 3164 June 8, 2007 Texas Register
