Current through Vol. 41, No. 20, July 1, 2024
(a)
Scope.
This Subchapter
				  establishes requirements for the use of radiation machines (x-ray systems and
				  particle accelerators) for therapeutic purposes in the healing arts and in the
				  practice of veterinary medicine.
(b)
Applicability.
The
				  requirements of this Subchapter apply to any person who possesses a therapeutic
				  system described in subsection (a) of this section and causes radiation to be
				  produced through the operation or testing of the machine in the
				  state.
(c)
Authorization
				  required.
No persons subject to this Subchapter may perform any
				  radiation management activity with such a therapeutic system unless:
(1) they hold a DEQ-issued radiation machine
				  operating permit and have registered their system with DEQ;
(2) their therapeutic systems and management
				  of radiation safety meet the applicable requirements of this Chapter;
				  and
(3) they are supervised by a
				  practitioner as defined in this section.

Current through Vol. 41, No. 20, July 1, 2024
(a)
Designation of authorized
				  practitioners.
Permit applicants, whose therapeutic systems will be used
				  to treat humans, must designate in their application the practitioners who will
				  supervise treatments and certify that those designees have had substantial
				  training and experience in the therapy techniques for which they will be
				  authorized.
(b)
Treatment
				  plan.
A treatment plan in written or electronic form must be approved by
				  an authorized practitioner before the initial administration of therapeutic
				  radiation.
(1) The treatment plan must contain
				  the patient's name, dose per fraction, number of doses, total dose, and
				  sufficient information to accurately describe proper localization of the
				  therapeutic dose.
(2) If, because
				  of the emergent nature of the patient's condition, a delay in order to provide
				  a treatment plan or revision to a treatment plan would jeopardize the patient's
				  health, an oral directive is acceptable. The information in the oral directive
				  must be documented in writing as soon as possible. A treatment plan must be
				  prepared within 48 hours of the oral directive.
(3) Permittees shall retain records of each
				  treatment plan for 3 years.

Current through Vol. 41, No. 20, July 1, 2024
(a)
Machines.
DEQ may prohibit
				  use of machines which pose significant threat or endanger health and
				  safety.
(b)
Exposure.
Individuals shall not be exposed to the useful beam except for healing arts
				  purposes and unless such exposure has been authorized by a practitioner. This
				  provision specifically prohibits deliberate exposure of an individual for
				  training, demonstration, or other non-healing arts purposes.
(c)
Security.
A therapeutic
				  system shall not be left unattended unless the system is secured against
				  unauthorized use.

Current through Vol. 41, No. 20, July 1, 2024
(a)
Communication and viewing requirements.
Therapeutic systems with
				  energies of less than 1 MeV that are capable of operating above 50 kVp must
				  provide the operator at the control panel:
(1)
				  a means of two-way communication with the patient at all times. This
				  communication must be aural unless excessive noise levels or treatment
				  requirements make an alternate method of communication necessary; and
(2) a means to be able to continuously
				  observe the patient from the treatment control panel during irradiation via a
				  primary viewing system such as a window, mirror, closed-circuit television or
				  the equivalent. When the primary system is electronic, an alternate viewing
				  system, which may also be electronic, must be available in case the primary
				  system fails. Should both viewing systems fail or become inoperative, treatment
				  must be stopped until at least one of the systems is restored.

Leakage
				  radiation measurements.
For operating conditions producing maximum

				  leakage radiation, including x-rays, electrons and neutrons, shall not exceed
				  0.1 percent of the maximum absorbed dose in rads of the unattenuated useful

				  measured at any point in a circular plane of 2 meters radius centered on and
				  perpendicular to the central axis of the beam at the isocenter or normal
				  treatment distance and outside the maximum useful beam size; and the maximum
				  absorbed dose shall be measured at the point of intersection of the central
				  axis of the beam and the plane surface.
(1)
				  Measurements excluding those for neutrons shall be averaged over an area up to
				  but not exceeding 100 square centimeters at the positions specified.
(2) Measurements of the portion of the
				  leakage radiation dose contributed by neutrons shall be averaged over an area
				  up to but not exceeding 200 square centimeters.

(2) For post-1989 systems which utilize wedge
				  filters, interchangeable field flattening filters, or interchangeable beam
				  scattering foils:
(A) irradiation shall not
				  be possible until a selection of a filter has been made at the treatment
				  control panel or a positive selection to use "no filter";

				  irradiation if the filter selected is not in the correct position;
(C) a display shall be provided at the
				  treatment control panel identifying the filter(s) in use; and

(a)
Radiation
				  detectors and dose monitors.
All systems of 1 MeV or more must have
				  radiation detectors in the radiation head. Post-1989 systems must have at least
				  two radiation detectors which are incorporated into two separate dose
				  monitoring systems. Pre-1989 systems must have at least one radiation detector
				  which is incorporated into the primary dose monitoring system. The detector and
				  the dose monitor system into which that detector is incorporated must meet the
				  following requirements:
(1) The detector must
				  be removable only with tools and be interlocked to prevent incorrect
				  positioning;
(2) Each detector must
				  form part of a dose monitoring system. The detector must show dose monitor
				  units which can be used to calculate the absorbed dose at a reference point in
				  the treatment volume; and
(3) Each
				  dose monitoring system must be capable of independently monitoring,
				  interrupting and terminating irradiation. For post-1989 systems with two or
				  more dose monitoring systems, the malfunctioning of one system must not affect
				  the correct functioning of the second system. If any element common to both
				  systems that could affect the correct function of both systems fails, the dose
				  monitoring system must terminate irradiation.

When a post-1989 system of 1 MeV or more is inherently

					 percent, the asymmetry of the radiation beam in two orthogonal directions shall

					 axis dose rate, devices shall be provided which will indicate this condition on
					 the control panel. If the difference exceeds 10 percent, the system must
