stored , used or transported.
(a) Instruments shall have a range such that 2
MR/HR through 1R/HR can be measured.
(b ) Each instrument shall be calibrated at
intervals not to exceed three ( 3) months.
The date of calibration and the date of re-
calibration shall appear on a label attached
to the instrument. If instruments require
repairs, they shall be calibrated following
such repairs. It shall be the responsibility
of the RSO to assure instrument calibration
occurs when the instrument is due. Records
of survey meter calibrations shall be kept
for a minimum of two (2) years.
( c) The operating condition of each instrument
shall be checked prior to use. Instruments
with weak batteries or doubtful operability
for any reason shall be brought to the atten-
tion of the RSO or ARSO. The RSO or ARSO
5.
shall remove any improperly functioning
instrument from service, mark it appropriatly

.,
�� i
(3 ) The radiographer shall establish a preliminary con-
trol by conspicously posting an area that will pre-
vent anyone at the perimeter of these areas from
receiving a dose in excess of 2 mr/hr. Preliminary
control is established by using approximate perimeters
described in 3. 3. 7 Attachment "C", "Radiation Inten-
sities and Distance Charts". Both "Radiation Area"
and "High Radiation Area" perimeters may be estab-
lished by Attachment "C" . Posting of these areas
shall be accomplished by using "Caution- Radiation
Area" and "Caution- High Radiation Area" signs.
During exposure, the perimeter of the "Radiation
Area" shall be adjusted by surveying the perimeter
and adjusting to a 2 mr/hr level .
( 4) After each exposure, upon returning the source into
the exposure device, the radiographer shall survey the
device and the source tube ( s ) to assure the source is
in a safe stored position within the device.
(5 ) Upon completion of daily radiographic operations and
prior to storage, the radiographer shall accomplish a
survey of the exposure device. If excessive levels of
radiation exist, place a "Hold Tag" on the device,
place it in storage and notify the ARSO or the RSO.

(d) Locate the device at the desired distance from
the object to be radiographed.
(e) Locate the control unit at the maximum distance
possible from the device. Whenever possible,
locate controls behind available protective
shielding.
( f ) Establish area security in accordance with para-
graph 3. 2. 5 (3) of these operating procedures.
( g ) Secure the source tube tip in the desired position
and distance from the object to be radiographed.
Attach one or two ( 1 or2) lengths of source tube
to reach the device. Each tube is seven feet in
length. DO NOT attach more than three (3) tubes,
or 21 feet, including tip, to the device. These
tubes shall be laid out as straight as possible
to avoid bends , particularly bends of sharp
radius .
(h) With a survey meter in the direct proximity of the
shipping plug of the device, remove the shipping
plus making certain the source is contained safely
within the device, and connect the source tube( s)
to the device.
( i ) Unlock the device.
( j ) Expose the source pigtail and attach the drive
cable to the source connector. Physically move
the connection around to assure that the drive
cable will not detach from the source pigtail . If
there is considerable "slop" or you have diff-
iculty in connection or disconnecting, notify the
ARSO or the RSO of the problem and let them
correct the situation. DO NOT attempt to correct
the problem on your own.
( k ) Return to the control unit with the survey meter.
DO NOT leave the meter in the high radiation area.
Cranking the control handle in a clockwise or
counter-clockwise direction, move the source out
of the device, observing the survey meter, through
the tube ( s ) to the source positioning tip. Undue
pressure could damage the connection. It is im-
portant, therefore, not to force the crank.
Moving the source through the tube ( s ) should be
accomplished as rapidly as possible.
42.
( 1 ) If undue resistance is encountered while moving
the source into the exposure position. return the
source to the device and correct the cause of the
resistance, if possible. DO NOT attempt to force
the source beyond the point of resistance.
(m) if undue resistance is encountered while return-
ing the source to the device upon completion of an
exposure, reverse the direction of the cranking
until the unit operates smoothly. If , after a few
reversals , cranking is still difficult, maintain
the area security and notify the ARSO or the RSO.
Observe the emergency procedures as stated in
section 4. 0 of this manual . The ARSO or RSO will
determine the steps to be taken and further
notification if required.
(n) Upon completion of an exposure, while observing
the survey meter, rapidly return the source to the
sheilded position by turning the control handle
in a clockwise or counter-clockwise direction
until the meter indicates it has been sheilded.
Approach the device with the survey meter turned
to the X10 scale, observing to assure that radia-
tion levels are not unusual . Survey the device
for 360 degrees around. It should be noted here
that if meter readings are excessively lower than
the readings taken when the device was removed
from storage, the source may be ,yet out in the
tube( s ) . Survey the guide tube ( s ) . Physically
place the device in a "source secured" position
by rotating the locking ring on a T. O. 660 and
680 or by observing the "pop-up" flag on the INC
IR-100. Place the survey meter adjacent to the
tube connection on the front of the device to
assure the source is properly housed.
(o ) Prior to moving the device from one location to
another , it shall be physically locked to prevent
accidental exposure of the source from the device.
( p) Upon completion of an assignment and the above
safety check, lock the device, remove the source
tube( s ) and insert the shipping plug. Unlock the
device, rotate the locking ring to connect and
remove the control cables. Dismantle the set-up
and return the device to the storage area.
Survey the storage area to assure safe radiation
levels are in effect.

INSPECTION AND MAINTENANCE PROCEDURES
FOR EXPOSURE DEVICES
INSPECTION
To insure safety in use and to avoid malfunctions that could impair
the productivity of this equipment, it is strongly recommended that
daily and periodic inspections be made. Missing or defective compon-
ents must be replaced or repaired if the equipment is to function as
designed.
Equipment and Material
Source Changer
Wrenches, screwdriver and allen keys
Basin approximately 12" diameter
2 Quarts solvent (perchlorethylene)
Syringe
Lubricant 2 oz. Texaco "Unitemp" grease
Dummy Source Assembly
Procedure
Remove the source from the unit and store it in the source changer.
Follow the instructions for the use of the source changer.
Control
Detach from shield, eject and coil source drive cable by cranking
control in EXPOSE direction. Examine cable for kinks, fraying, broken
wires or rust. Minor bends in the cable may be straightened by hand.
Do not use pliers. A cable with frayed or broken wires must be replaced.
Light rust may be removed by hand wire brushing. Do not use a powered
brush or abrasives. Heavy rust that has penetrated into the cable will
cause unsatisfactory operation or complete failure. Replace cable.
Clean the cable by immersing the coil in solvent. A heavy accumulation
of dirt laden lubricant may require more than one washing.
Examine the connector. Examine cable attachment to connector for
straightness and evidence of looseness. A loose attachment or bend
at this point must be repaired. Do not attempt to fabricate a re-
55•
.-� placement connector or to fasten it to the cable. The connector is
a special heat treated steel made to exacting tolerances and under
strict metallurgical control . The attachment is swaged with special
tools and proof tested. Order a replacement from Technical Operations.
Lubricate the cable with Texaco "Unitemp" grease. This is the most
satisfactory lubricant for this purpose. Common greases can cause
gumming and unsatisfactory operation. Take care in handling the
cable to avoid picking up dirt or grit.
Control Crank
Remove control cable housings by undoing fitting nuts. Remove crank
unit from reel , remove crank and disassemble. Wash parts in solvent.
Check inside of housing for evidence of galling and wear. A deeply
scored (more than .020 deep) line where the cable contacts the inner
wall of the housing indicates the need for replacement.
Check clearance between the hubs of the wheel and the bushing. More
than .005 clearance indicates replacement.
Examine teeth of wheel for damage. A bent tooth may be filed off.
Two or more bent teeth adjacent will require replacement of the wheel .
Lubricate bushings with Unitemp grease and reassemble.
Control Cable Housings
Examine carefully for internal damage by flexing the housings by
hand. Internal damage to the reinforcing braid or flexible metallic
tube will be evidenced by a crunch feeling when the cable housing is
flexed. Cut, flattened or burnt cable housings should be replaced.
Superficial cuts or burns may be sealed and reinforced with tape.
Clean housings by syringing a few ounces of solvent into bore and
blow out with low pressure air. (Not more than 20 psi ) . Do not
allow solvent to remain. Do not soak in solvent. Check end fittings
for secure attachment.
Source Guide Tubes
Check for cuts, burns or crushed tubes. Check fittings for secure
attachment. Examine and test screw threads for function. Clean
bore of tube with water or solvent and drain out promptly. Do not
soak in solvent. Check for free passage of source by holding tube
vertically and dropping dummy source assembly through tube. The dum-
my source assembly should fall through freely.
56.
i
Shield Assembly
Check exterior for loose or missing hardware. Replace or tighten as
required. Examine source exit fitting. Nut should rotate freely with-
out excessive shake. Look into exit port and check concentricity of
source tube with nut. Misalignment, if found, indicates a damaged
housing or shifting of the shield within the housing. This is best
repaired by the device manufacturer. We do not recommend disassembly
of the shield assembly. Pour an ounce or so of solvent through the
source tube from the cable connector end. Drain.
Examine the shield assembly for complete labels and warning symbol .
Replace obliterated or illegible marking. Adhesive backed replace-
ments are available from the device manufacturer.
Final Inspection
Reassemble system, connect control cables and source guide tubes to
shield and install dummy source. Operate machine several times to
be sure of proper function. Check operation of the source position
indicator system. Refer to the electrical schematic for guidance
in locating faults. A volt-ohmmeter may be used for measuring volt-
ages and checking circuit continuity.
Return live source to shield and make a gamma ray survey. Radiation
levels must not exceed the following:
At one meter (39-3/8 inches)
Not more than 0.066 mr. per curie
At 6 inches from the surface
Not more than 0.33 mr. per curie
