RADIATION SAFETY REQUIREMENTS FOR INDUSTRIAL RADIOGRAPHIC OPERATIONS

Equipment Control: Permanent Radiographic Installations
(1) 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 OAR 333-120-0220 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 signal must be actuated by radiation whenever the source is exposed. 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.
(2) 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 section (1)(a) of this rule 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 seven calendar days. The facility may continue to be used during this seven-day period, provided the licensee implements the continuous surveillance requirements of 333-105-0580 and uses an alarming rate-meter. Test records for entrance controls and audible and visual alarms must be maintained in accordance with 333-105-0670.
