Section 180-8-004 - AREA REQUIREMENTS

Areas where radiation generating devices are located must meet the requirements of this section.

004.01RADIATION LEVELS. The local components of radiation generating devices must be located and arranged, and include sufficient shielding or access control, so that radiation levels in any area surrounding the local component group cannot result in a dose to an individual present in that area in excess of the dose limits given in 180 NAC 4-013. For systems utilizing x-ray tubes, these levels must be met at any specified tube rating.

004.02SURVEYS. Facilities with radiation generating devices must have surveys completed as required by 180 NAC 4-021. The surveys must be sufficient to show compliance with 180 NAC 8-004.01 and must be performed:

(i) Upon installation of the equipment and at least once every 12 months thereafter;

(ii) Following any change in the initial arrangement, number, or type of local components in the system;

(iii) Following any maintenance requiring the disassembly or removal of a local component in the system;

(iv) During the performance of maintenance and alignment procedures if the procedures require the presence of a primary x-ray beam when any local component in the system is disassembled or removed;

(v) After bypass of a safety device or interlock;

(vi) Any time a visual inspection of the local components in the system reveals an abnormal condition; and

(vii) Whenever personnel monitoring devices show a significant increase over the previous monitoring period or the readings are approaching the limits specified in 180 NAC 4-005.

004.02(A)DEMONSTRATION OF COMPLIANCE. Radiation survey measurements will not be required if a registrant can demonstrate compliance to the satisfaction of the Department with subsection 004.01 in some other manner.

004.03POSTING. Each area or room containing radiation generating devices must be clearly posted with a sign or signs bearing the radiation symbol and the words "CAUTION X-RAY EQUIPMENT", or words having a similar intent, according to 180 NAC 4-033.
