(b) Before each patient
treatment with a low dose-rate remote afterloader unit; and
(c) After each source
installation.
(2)
Spot-checks shall include the determination of:

afterloader unit room entrance;
(b)
Source exposure indicator lights on the remote afterloader unit, on the control
console, and in the facility;
(c)
Viewing and intercom systems in each high dose-rate, medium dose-rate, and
pulsed dose-rate remote afterloader facility;
(d) Emergency response equipment;
(e) Radiation monitors used to indicate the
source position;
(f) Timer
accuracy;
(g) Clock (date and time)
in the unit's computer; and
(h)
Decayed source(s) activity in the unit's computer.
(3) If the results of the checks required in
subsection
64E-5.6421(2),
F.A.C., of this section indicate the malfunction of any system, a licensee

(6) A licensee shall
retain a copy of the procedures required by subsection

(5), F.A.C., until the licensee no longer
possesses the remote afterloader unit. The record shall include:
(a) The date of the spot-check;
(b) The manufacturer's name, model number,
and serial number for both the remote afterloader unit and source;
(c) An assessment of timer
accuracy;
(d) Notations indicating
the operability of each entrance door electrical interlock, radiation monitors,
source exposure indicator lights, viewing and intercom systems, and clock and
decayed source activity in the unit's computer; and
(e) The name of the individual who performed
the periodic spot-check and the signature of the authorized medical physicist
who reviewed the record of the spot-check.
