Section R12-1-539. Permanent Radiographic Installations

A.      If a licensee maintains a permanent radiographic installation that does not fall within the definition of “enclosed radiogra- phy” in R12-1-102, the licensee shall ensure that each entrance, used for personnel access to the high radiation area, has either:

1.        An entrance control device of the type described in R12- 1-420(A)(1) that reduces the radiation level upon entry into the area, or

2.        Both conspicuous visible and audible alarm signals to warn of the presence of radiation. The  licensee shall ensure that the visible signal is actuated by radiation if a source is exposed and the audible signal is actuated if someone attempts to enter the installation while a source is exposed.

B.       A licensee with an alarm signal shall test the alarm signal for proper operation with a radiation source each day before the installation is used for radiographic operations. The test shall include a check of both the visible and audible signals. A licensee with an entrance control device shall test the device monthly. If an entrance control device or alarm signal is oper- ating improperly, the licensee shall immediately label the device or signal as “defective” and repair the device or signal within seven calendar days. The licensee may continue to use the facility during this seven-day period, if the licensee imple- ments continuous surveillance requirements of R12-1-509 and uses an alarming rate meter.

C.      A licensee shall maintain each record an alarm system or entrance control device test for three years after the record is made.
