Ariz. Admin. Code § R9-7-539 - Permanent Radiographic Installations
A. If a licensee maintains a permanent
radiographic installation that does not fall within the definition of "enclosed
radiography" in
R9-7-102, 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
R9-7-420(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 operating
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 implements continuous surveillance requirements of R9-7-509 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.
