film-screen combination to be used, if any;
(3) type of the grid to be used, if any; and
(4) source-to-image receptor
distance to be used.

Safety procedures. Written operating and safety procedures shall
be made available to each individual who operates diagnostic x-ray systems.
These procedures shall include restrictions required for the safe operation of
each diagnostic x-ray system.
(c)
Radiation dose limitation and personnel monitoring. Except as
otherwise exempted, all individuals who are associated with the operation of a
diagnostic x-ray system are subject to the radiation dose requirements of
310:281-9-2,
310:281-9-3,
310:281- 9-5 regarding dose limits to individuals,
310:281-9-40

required, the whole body badge shall be worn in accordance with
310:281-9-12(d).
The dose measured by this device shall be recorded as the whole body dose on
the personnel radiation exposure records, as required by
310:281-9-29.
(2) Protective equipment including aprons,
gloves, and shields shall be checked annually for defects, such as holes,
cracks, and tears to assure reliability and integrity. A record of this test

is found, equipment shall be replaced or removed from service until repaired.
(e)
Information
and records. The permittee shall maintain the following information for
each diagnostic x-ray system for inspection by the Department:
(1) records of receipt, transfer, and
disposal;
(2) a copy of all
correspondence to and from the Department regarding each diagnostic x-ray
system; and
(3) records of surveys,
calibrations, spot checks, maintenance, and modifications performed on the
diagnostic x- ray system. The signature of the individual performing the
service and the date it was performed shall be on the record.
(f)
Operator
training. Individuals who operate diagnostic x-ray systems shall be
instructed in and be able to demonstrate competence with the permittee's
operating and safety procedures.
(g)
Healing arts screening. Any
person proposing to conduct a healing arts screening program for humans shall
not initiate such a program without prior approval of the Department. When
requesting such approval, that person shall submit the information outlined in
310:281-11-21.
If any information submitted to the Department becomes invalid or outdated, the
Department shall be notified within 15 days.
(h)
Processor control.
(1) In conjunction with all human diagnostic
x-ray systems, all processors shall be maintained on a predetermined schedule
for quality assurance.
(A) A log shall be
kept that states the following:
(i) type of
test;
(ii) acceptability limits for
that particular test;
(iii) results
of the test;
(iv) the date the test
was performed;
(v) initials of
technician or testing individual;
(vi) if needed, corrective action taken.
(B) Tests shall include,
but not be limited to, fog test, chemical replacement, and darkroom light
leak.
(C) All processing shall be
by the time/temperature method. The predetermined method shall be documented
and state the manufacturer, development time, and type of all chemicals used in
the film processing method (including hand processing methods).
(D) Deviations from the recommended use (as
detailed by the manufacturer) or changes in the method or manufacturer shall be
documented (date, initials of technician) in the processor log.
(E) Lighting in the film processing/loading
area shall be with the filter, bulb wattage, and distances recommended by the
film manufacturer for that film emulsion. When 2 or more types of film are
used, the more sensitive type will be accommodated.
(2) For dental and veterinary diagnostic
x-ray systems, the film manufacturer's recommendations, including maintenance
of the equipment and maintenance of the developing solutions of a constant
temperature, shall be used for processing film.
(i)
Diagnostic x-ray system
requirements. Each permittee is responsible for satisfying the following
diagnostic x-ray equipment requirements:
(1)
Warning label. The control panel containing the main power switch
shall bear the radiation symbol and a statement, legible and plainly visible to
view, containing the following or similar wording: " WARNING" or " Caution":
"This machine produces radiation when energized."
(2)
Mechanical support of tube
head. The tube housing assembly shall be adjusted such that it will
remain stable during an exposure. If tube housing movement is a designed
function of the diagnostic x-ray system the tube housing assembly shall be
adjusted such that it will remain stable except during such a designed
function.
(A) The tube housing assembly
supports shall not be hand-held.
(B) Veterinary portable units designed to be
hand-held are exempted if they provide a diagnostic-type tube housing.
(j)
Film
and image retention. Human radiographic images shall be retained for a
minimum of five years with the exception of mammographic images. In accordance
with
