Fla. Admin. Code Ann. R. 64E-5.431 - Permanent Radiographic Installations
(1) Each entrance used for personnel access
to a high radiation area in a permanent radiographic installation shall have
either:
(a) An entrance control that reduces
the radiation level to below the level at which an individual might receive a
deep dose equivalent of 0.1 rem (1 millisievert) in 1 hour at 30 centimeters
from the source of radiation from any surface the radiation penetrates,
or
(b) Conspicuous visible and
audible signals to warn of the presence of radiation. The visible signal shall
be actuated by radiation. The audible signal shall be actuated when an attempt
is made to enter the installation while the source is exposed or the radiation
machine is activated.
(2) The alarm system shall be tested for
proper operation with a radiation source each day before radiographic
operations. The test shall include a check of both the visible and audible
signals. Entrance control devices that reduce the radiation level upon entry
shall be tested monthly. If an entrance control device or an alarm is operating
improperly, it shall be labeled immediately as defective and repaired within 7
days. The installation can continue to be used by an unaccompanied radiographer
during this 7-day period if the continuous surveillance requirements of
subsection
64E-5.425(6),
F.A.C., are implemented and an alarming ratemeter is used.
