333-122-0320 Permanent X-ray Radiography Installations (1) Each entrance that is used for personnel access to the radiation area in a permanent radiography 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. (A) The visible signal must be actuated by radiation whenever the machine is energized. (B) The audible signal must be actuated when an attempt is made to enter the installation while the machine is energized. (2) The alarm system must be tested for proper operation with an X-ray machine each day before the installation is used for RGD X-ray operations. (a) The test must include a check of both the visible and audible signals. (b) Entrance control devices that reduce the radiation level upon entry as designated in OAR 333-120-0220(1)(a) must be tested monthly. (c) 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 X-ray machine may continue to be used during this seven-day period, provided the registrant implements the continuous surveillance requirements of OAR 333-122-0326 and uses an alarming rate-meter. (d) Test records for entrance controls and audible and visual alarms must be maintained in accordance with OAR 333-122-0326. (3) RGD X-ray machines must be physically secured to prevent tampering by unauthorized personnel. (4) In addition to the training requirements in OAR 333-120-0160, permanent X-ray radiography operators must adhere to the following requirements: (a) The registrant may not permit any individual to act as an X-ray radiography machine operator until the individual has received on the job training consisting of hands-on experience under the supervision of a qualified X-ray radiography machine operator. The on the job training must include a minimum of one month (160 hours) of active participation in the performance of industrial X-ray utilizing X-ray machines. (b) Except as provided in this rule, the radiation safety officer or designee must conduct an inspection program of the job performance of each X-ray radiography machine operator to ensure that the Authority's rules, registration requirements, and operating and emergency procedures are followed. The inspection program must: (A) Include observation of the performance of each X-ray radiography operator during an actual industrial radiographic X-ray machine operation, at intervals not to exceed six months. (B) Provide that, if an X-ray radiography machine operator has not participated in an industrial X-ray radiography operation for more than six months since the last inspection, the individual must demonstrate knowledge of the training requirements of this rule by a practical examination before these operators can next participate in a radiation machine operation. (c) The Authority may consider an alternate individual to conduct the inspection program and observation of the RGD operator as required in (4)(b)(A) and (B) of this rule, in those situations where the radiation machine operator is also the radiation safety officer. (d) In those operations where a single individual serves as both X-ray operator and radiation safety officer, and performs all industrial X-ray machine operations, an inspection program is not required.
