  31C [DPH] RADIATION

  SECTION 3101C—SCOPE

  For the purpose of this chapter, the following terms shall have the meaning indicated:

  PRIMARY PROTECTIVE BARRIER is a barrier to attenuate the useful beam.

  SECONDARY PROTECTIVE BARRIER is a barrier to attenuate stray radiation.

  STRAY RADIATION is radiation not serving any useful purpose, which includes leakage and scattered radiation.

  USEFUL BEAM is the radiation which passes through the window, aperture, cone or other collimating device of the tube housing.

  SECTION 3102C—RADIATION SHIELDING BARRIERS

  All radiation shielding barriers in rooms and enclosures housing machines shall meet the requirements of Section 12-31C-101, Chapter 12-31C, Part 12, California Referenced Standards Code. The Department of Health Services is the only agency that may grant a variance or exception to these standards.

  SECTION 3103C—MEDICAL RADIOGRAPHIC AND PHOTOFLUOROGRAPHIC INSTALLATIONS

  3103C.1 Operator station. The operator’s station at the control shall be behind a protective barrier either in a separate room, in a protected booth or behind a shield which will intercept the useful beam and any radiation which has been scattered only once.

  3103C.2 Patient observation and communication. Provision shall be made for the operator to observe and communicate with the patient without leaving the shielded position at the control panel. When an observation window is used, it must provide radiation atten- uation equal to that required in the surrounding barrier.

  SECTION 3104C—MEDICAL THERAPEUTIC X-RAY INSTALLATIONS

  3104C.1 General. All wall, floor and ceiling areas that can be struck by the useful beam, plus a border of 1 foot (305 mm), shall be provided with primary protective barriers.

  3104C.2 Equipment operating above 50 kVp. Equipment operating above 50 kVp shall conform with the following: 1. The control station shielding shall either be an integral part of the building or anchored to the building. 2. The control station shall be provided with a window having radiation attenuation equal to that required by the adjacent barrier, or a mirror system, or a closed-circuit television viewing screen. The patient area must be visible to the operator with- out having to leave the protected area during exposure.

  3104C.3 Equipment operating above 150 kVp. Equipment operating above 150 kVp shall conform to the following: 1. The treatment room shall be provided with interlocks so that when any door of the treatment room is opened, either the machine will shut off automatically or the radiation level within the room will be reduced to an average of not more than 2 milliroentgens per hour and a maximum of 10 milliroentgens per hour at a distance of one meter in any direction from the target. After such shutoff or reduction in output, it shall be possible to restore the machine to full operation only from the control panel. 2. The control station shall be within a protective booth or in an adjacent room.

  3104C.4 A minimum of one door shall be provided with an auxiliary means for being opened in case of power failure or mechanical breakdown, where large power-driven doors offer the only access to the room.

  3104C.5 A flashing red warning signal light energized only when the useful beam is on shall be located adjacent to the entrance(s) to a therapy room with equipment capable of operating above 500 kVp.

  3. The drawing shall show a pictorial view of the installation terminals or leads to which field connections are made as they would appear when viewed during an installation and the minimum internal dimensions of a back box, if not provided with the detector, shall be specified. The terminal numbers on the detector shall agree with the numbers on the drawing. A drawing not attached to the detector unit shall be marked with the name or identifying symbol of the manufacturer’s or vendor’s drawing number, and an issue number and/or date.
  4. The following marking information is required to appear on the detector or the installation wiring diagram for the applicable circuits to which field connections are made. Where an electrical rating is indicated, it may be omitted if reference is made for connection to a specific control unit or equivalent. A. Supply circuit. Voltage, current or watts, and frequency. B. Initiating device circuit connections. For detectors intended to be connected only to the initiating device circuit of a fire alarm system control unit, at least two detectors shall be shown connected to a typical initiating device circuit. For a detector intended only for releasing device service, a typical connection shall be shown. For a detector suitable for both application, typical connections representing both types of connections shall be illustrated. C. Supplementary circuits. Voltage, current or watts, and frequency rating.
  5. Technical bulletin. A technical bulletin shall be provided by the manufacturer for each installation to be used as a reference by the installer. The bulletin shall include the manufacturer’s recommendations regarding typical detector locations. The information shall include guidelines on detector location, spacings, maintenance, servicing tests, etc., under various environmental conditions and physical configurations. Some conditions for which guidelines are required are:

  A. Temperature B. Humidity C. Corrosive atmospheres D. Air movement (ventilating and air-conditioning systems) E. High ceilings F. Sloped ceilings G. Girder ceiling construction H. Small and large bays I. Open joist construction J. High stock piling K. Conditions produced by manufacturing processes 6. Detailed information shall be provided regarding the use of the facilities provided on the detector to monitor the sensitivity. Typical information that shall be provided includes: A. Nominal reading under clear condition B. Nominal reading when close to alarm C. Nominal reading at alarm condition D. Guidelines on instrument use for an engineering survey, installation and maintenance 7. Information regarding locations where not to install detectors shall also be provided to minimize the possibility of false alarms.
