Current through March 20, 2024

012.01 ENTRANCE. Each entrance that is used for personnel access to the high radiation area in a permanent radiographic installation must have either:

(A) An entrance control of the type described in 180 NAC 4-023.01(A) that causes the radiation level upon entry into the area to be reduced; or

(B) Both conspicuous visible and audible warning signals to warn of the presence of radiation. The visible sign must be actuated by radiation whenever the source is exposed or the machine is energized. The audible signal must be actuated when an attempt is made to enter the installation while the source is exposed or the machine is energized.

012.02 ALARM SYSTEM TEST. The alarm system must be tested for proper operation with a radiation source each day before the installation is used for radiographic operations. The test must include a check of both the visible and audible signals. Entrance control devices that reduce the radiation level upon entry as designated in 180 NAC 5-012.01(A) must be tested monthly. If an entrance control device or an alarm is operating improperly, it must be immediately labeled as defective and repaired within 7 calendar days. The facility may continue to be used during this seven day period, provided the licensee or registrant implements the continuous surveillance requirements of 180 NAC 5-021 and uses an alarming ratemeter. Test records for entrance controls and audible and visual alarms must be maintained as required by 180 NAC 5-030.
