Illinois Administrative Code › Title 32 - ENERGY › Part 360 - USE OF X-RAYS IN THE HEALING ARTS INCLUDING MEDICAL, DENTAL, PODIATRY, AND VETERINARY MEDICINE › Section 360.120 - Therapy Systems Operating at 1 MeV or Greater

Current through Register Vol. 48, No. 28, July 12, 2024
In addition to the provisions of Sections
				360.10 through
				360.30,
				the requirements of this Section apply to particle accelerator systems
				operating at energies of 1 MeV or greater. Accelerator systems capable of
				producing radioactive materials in excess of the exempt quantities specified in
				32 Ill. Adm. Code 330. Appendix B shall also be licensed pursuant to the
				provisions of 32 Ill. Adm. Code 330.
a) Facility Design
1) The registrant shall consult a therapeutic
			 radiological physicist in the design of a particle accelerator
			 installation.
2) Shielding
			 Requirements
A) Each accelerator installation
			 shall be provided with such primary and secondary barriers as are necessary to
			 assure compliance with 32 Ill. Adm. Code 340.
B) Facility design information for all
			 accelerators installed after October 15, 1993 shall be submitted to the Agency
			 for review prior to installation. Information submitted to the Agency shall
			 include, but need not be limited to, the following:
i) Name and address of the planned
			 installation;
ii) Name, address and
			 telephone number of the therapeutic radiological physicist who was consulted in
			 the design of the installation;
iii) A scale drawing that includes the
			 location of the accelerator, control panel and doors to the room;
iv) The structural composition and thickness
			 of all walls, doors, partitions, floor and ceiling of the
			 installation;
v) The occupancy of
			 areas adjacent to the installation;
vi) Calculations that demonstrate the
			 adequacy of the amount of shielding specified for each primary and secondary
			 protective barrier; and
vii)
			 Projected weekly dose rates in areas adjacent to the installation.
3) Interlock. An
			 interlock shall be installed on each door of the therapy room. The interlock
			 shall be wired into the electrical circuit in such a manner that when the door
			 is opened for any reason, the generation of radiation beams will automatically
			 be terminated and irradiation can be resumed only by manually resetting the
			 controls on the control panel after the door is closed.
4) Warning lights that indicate when the beam
			 is on shall be provided in a readily observable position near the outside of
			 all access doors to the therapy room.
5) Viewing System. Windows, mirrors,
			 closed-circuit television or an equivalent system shall be provided to permit
			 continuous visual observation of the patient during irradiation and shall be
			 located so that the operator can observe the patient from the control panel.
AGENCY NOTE: When the primary viewing system is electronic, a
				back-up system should be available for use in the event of failure of the
				primary system in order to ensure compliance with the requirements of
				subsection (g)(1)(H).
6)
			 The facility design shall permit two-way aural communications between the
			 patient and the operator at the control panel.
7) Signs required by 32 Ill. Adm. Code
			 340.920
			 shall be posted in the facility.
8)
			 The control panel shall be outside the therapy room.
9) The facility design shall include
			 emergency off buttons, at locations that allow shutting off the machine from
			 inside the therapy room and at the control panel.
10) The doors to the therapy room shall be
			 designed to allow opening from the inside at all times and shall be capable of
			 being opened manually.
