1 1.0 SCOPE
]
1.1 in conformance with 10 CFR part 34, Professional Welding Associates has developed this program of operating and emergency procedures. These procedures will provide radiography personnel with a guide for safe, consistent performance and documentation of radiographic operations.
Each radiographer and radiographer's assistant will be issued a copy of l
these procedures which shall be at their disposal at all times during l
radiographic operations.
2.0 DEFINITIONS 2.1 The following terms commonly used in this procedure are defined as follows:
1 RSO - Radiation Safety Officer.
I NRC - United States Nuclear Regulatory Commission.
O Rediooren er - eny individoei wne performs or who. in etiendence ei tne n
site where sealed sources are being used, personally supervises radiographic operations and who is responsible for assuring compliance with this program and the applicable NRC requirements.
f Radiographer's Assistant - any' individual who, under the personal supervision of a radiographer, uses radiographic exposure devices, sealed sources, related handling equipment, or radiation survey instruments in the performance of radiography.
Radiographic Exposure Device - Any instrument containing a sealed source fastened to or contained therein.
l Radiography - The examination of the structure of materials by nondestructive methods utilizing sealed sources.
]
Restricted Area - Any area access to which is controlled for purposes of protection of individuals from exposure to radiation and radioactive materials.
Sealed Sources - any by-product material that is encased in a capsule designed to prevent leakage or escape of the by-product material.

O Storage Area - Any location, facility, or vehicle which is used to store, transport, or secure a radiographic exposure device, storage container, or sealed source when it is not in use and which is locked or has a physical l
barrier to prevent accidental exposure, tampering with, or removal by l
unauthorized personnel.
i Storage Container - A device in which exposure devices are stored or I
transported.
i Source Changer - A device designed and used for replacement of sealed sources in radiographic exposure devices.
l 3.0 PRINCIPLES OF RADIATION SAFETY 3.1 Industrial radiography operations require the use of radiation sources having high energy and high emissivity. Unless these radiation safety precautions are understood and utilized, there is the possibility of overexposure. The information contained in these paragraphs contains the three basic principles for controlling personnel exposure which are (1)
Time, (2) Distance (3) and Shielding.
3.1.1 Time - Personal dosage depends directly upon the time a person remains in a radiation field. An individual that would receive only 3 l'
mR in 2 minutes at a given point, would receive 15 mR if he remained there for 10 minutes. Limiting the working time in a radiation field requires the conscientious use of survey instruments.
I 3.1.2 Distance - Lower personal exposure will be received at greater distances from the source of radiation. Simply, the greater the distance the lower the exposure.
l 3.1.3 Shielding - In the event that working time is too long or operating l
conditions prevent an adequate exposure distance, shielding, such as a collimator, may be placed between the source and personnel.
Shielding will not stop all the radiation but it can reduce the intensity to a level that will permit performance of radiography without excessive exposure to personnel.

5.1.1 Thermoluminescent Dosimeter (TLD) - Each individual will be issued i
a TLD bearing that persons name, a unique identification number, and the date of exchange. TLD's are to be worn on the upper body with the identification label facing outward. Care should be exercised not to damage the crystal recording medium inside, for example, TLD's should be removed from clothing before washing or the badge-will be destroyed. Also, do not leave badges near microwave ovens, l
color tv's, or on the dashboard of a vehicle since these actions may cause erroneous readings when the badge is processed.
I TLD's will be exchanged on a monthly basis.
l l
5.1.2 Pocket Dosimeters - Each individual will be issued a direct reading l
pocket dosimeter with a range of 0-200 mR. Each dosimeter must be calibrated annually and a calibration sticker will be applied showing i
l the date of calibration and the due date. Pocket dosimeters should be checked frequently during the course of radiographic operations.
Final daily readings shall be entered on the Dosimeter Log to the l
nearest 5 mR (exhibit #1). If during the course of operations the dosimeter readings approach the 200 mR limit, the dosimeter reading
.CJ continue. At the completion of radiography, the dosimeter shall be read again and the total of the two readings shall be entered on the j
Dosimeter Log. Do not drop the dosimeter, this can cause irreparable damage to the element inside. Dosimeters must be recharged at the i
start of each shift.
5.1.3 Pocket dosimeters shall be worn in conjunction with TLD's, if you do not have a dosimeter and TLD, you may not perform radiography.
5.1.4 Personnel performing radiography must wear an alarm rate meter.
This equipment will give an audible alarm when the radiation field is in excess of 500 mr/hr. Alarm rate meters shall be checked daily to ensure that the alarm functions properly. Alarm rate meters shall be calibrated annually.

1 of 2 QUARTERLY MAINTENANCE AND INSPECTION 1.0 PROCEDURE 1.1 Radiography equipment will receive a general maintenance and inspection every 90 days. If any part of the source assembly (pigtail) should need repair, do not attempt to do so in the field, if a source assembly should need repair notify the RSO. The quarterly maintenance procedure is as follows:
1.)
Remove the safety cap and inspect the source connector. The connector should not be damaged or show signs of excessive wear.
Check the connector for straightness at the flexible cable. If the connector is satisfactory, the mating connector should be connected to the source and about 30 to 40 pounds of pressure should be applied. If connector is damaged or inoperable, notify the RSO.
]
2.)
Inspect the lock mechanism for ease of operation. Dirt and other foreign matter may foul the mechanism and make it inoperative. The lock may be cleaned and lubricated by using a spraying lubricant such as WD - 40 into the lock. If necessary, the lock can be removed l
and washed in solvent. Caution: the camera must be empty before removing the lock.
l 3.)
Remove the safety plug and inspect the source outlet nipple. The i
outlet nipple should be round and smooth so that it will match with the 1. D. of the source tube. If the nipple is out of round it may be l
straightened by using a punch or round bar on the inside of the outlet. If it cannot be straightened or is broken the nipple must be replaced.
4.)
Inspect labeling on exposure device. All warning signs and source identification tags should be distinct and legible. If tags are not l
legible, they must be replaced.
2i 5.)
Inspect source tubes for damage such as crimps, foreign matter, ease of connecting, and disconnecting from exposure device.
,m, 6.)
Inspect source connector on drive cable. The connector should not i~
be damaged or excessively worn. If the connector shows any l
excessive wear or damage, the drive cable must be replaced.

Inspect the remainder of the drive cable for kinks, wear, or corroded sections that may become stiff and would prevent the cable from running in the gear box. The drive cable should be cleaned and soaked in solvent or diesel fuel.
8.)
The control assembly should be dismantled and the parts should be l
cleaned and re-lubricated. If the drive gears or bushings show excessive wear, they should be replaced.
9.)
Inspect the drive cable housing or conduit. In any case where the inner metal liner has been damaged, the conduit must be replaced.
If the outer covering has been damaged, water proof tape or a i
waterproof sealer can be applied to prevent moisture from entering and causing the drive cable to corrode.

- O 1.0 PROCEDURES FORSOURCE RECOVERY I
1.1 This procedure has been developed to provide the sequence of events that must take place if a source cannot be retracted or has been disconnected. It must be kept in mind that no set of procedures can take into account all the conditions j
that can come into play during a radiation emergency (i.e. type of source, curie strength, type of malfunction, terrain, environment, type of camera, type of i
j hook-up, recovery equipment available, etc., ).
)
1.2 in a situation where the radiographer cannot retract the source the radiographer shall contact the Radiation Safety Olficer or Manager of NDE Operations. He will i
will evaluate the information and make the proper decision as to the next step:
- 1 allow the radiographer to attempt the recovery (based on the radiographers experience, training and the anticipated difficulty of the recovery) or i
i
- 2, instruct the radiographer to keep the area under constant surveillance until the Radiation Saftey Officer or NDE Operations Manager with the proper equipment arrives at the job site. No matter which of the above is decided, the i
RSO shall be advised immediatly.
}
The RSO or Manager of NDE Operations shall:
(a) Determine the physical condition of the radiographer.
}
(b) Ascertain the condition of the survey meter.
(c) Confirm that the area has been restricted and posted, and is under constant surveillance.
J (d) Ascertain the condition of the exposure device.
1.3 If the physical condition of the radiographer is such that he is unable to perform his dulles, notify emergency medical help and instruct ihe assistant radiographer to maintain constant surveillance until assistance arrives. If there is no assistant radiographer available or able to restrict the area, the j
civil authorities must be notified and instructed to isolate the area until assistance arrives.
)
1.4 If the survey meter is not operational, no one shall enter the radiation area until l
assistance arrives. Employee or employees shall check their dosimeters at reasonable lengths of time to determine that they receive less than 5 Mr per hour. Constant surveillance shall be maintained.
i 1.5 Established restricted area's shall be maintained (or adjusted if necessary) so that no one outside the restricted area can receive more than 5 mr in any one hour. If the source is exposed at sorne time other than during radiographic operations (such as if the camera is drooped from some high place dislodging the source) a radiation area must be establiched until the source is recovered.
1.5 The condition of the exposure device and attachments will indicale the need for O
replacement equipment required for recovery.

J 1.6 Assuming there is no present danger of overexposure to employees or others it -
I must be determined what steps can be taken to recover the source or reduce the radiation to a safe level.
)
1.7 If the dosimeter of the radiographer has Dnigone over 200 mr (off scale) and a i
l discussion Indicates the type of recovery is well within his ability, it may be permissible to allow him to perform those functions that present little danger of overexposure and to make a recovery that is within his ability. This should be i
done on a case by case basis.
l 1.8 If the determination is made that the recovery should ba performed by the Manager of NDE Operations or the RSO, then it is necessary that constant
~
surveillance be maintained until assistance arrives.
l 2.0 Source Recoverv 2.1 The area shall be restricted and posted until the source is recovered and constant surveillance will be maintained.
2.2 Atleast one operational survey meter shall be used during all operations.
I 2.3 PRIORTO ANY SOURCE RECOVER' OPERATION A SPECIFIC PLAN BASED ON THE SITUATION WILL BE FORMULATED THAT WILL ALLOW THE RECOVERY TO BE MADE WITH THE MINIMUM EXPOSURE TO ANY INDIVIDUAL.
l 2.4 If at any time it is felt the recovery operations are beyond the capabilities of the individuals involved or there is doubt the recovery can be rrade safely, THE OPERATIONS WillBE DISCONTINUED AND THE RADIATION SAFETY OFFICER l
CONUCTED.

w Operate the hand cranks to drive the source to the end of the source tube. Refract the drive cable leaving the source in the end of the tube.' Working very quickly enter the area and place the lead sheets over the source to reduce the radiation level. * (check dosimeter after each trip, RECORD READING, and RECHARGE).
Enter the area and place a shipping container in the general area of the safe end of the source tube (camera end).
- With the source tube and source covered with lead disconnect the source tube from the camera.
- Using the safe end of the source tube (verify with survey meter) draw the source tube from under the lead and quickly lift the closed end of the source tube with the remote handling tongs and shake the source onto the ground. (This should be performed in such a manner some type of shielding is between the individual and the source.
- Enter the area and using the remote handling longs, grasp the hook-up end of the source placing it in the shipping container,
- CHECK ALL EQUIPMENT PRIOR TO RELOADING THE CAMERA.
i
- b. Source in the cuide tube (no disconnect) (tube damaaed).
This procedure can be followed in those cases where the source cannot be retracted thru the source tube due to damage to the tube. It is assumed the drive cable will pass thru the tube restriction (if not, add shielding to the source and c
notify the Radiation Safety Officer). Crank the source out to the end of the source tube and retract until the source is stopped by_ the restriction. Crank the source lO forward (toward the closed end) about two inches to be sure the source is nol l
lV jammed in the restriction.
- Enter the area and place lead sheets over the source l
until the radiation level will allow work to be performed at the end of the source t
tube without an overexposure. After each trip into the area with lead READ, RECORD. and RECHARGE DOSIMETER prior to continuing. Enter the area and remove the end from the source tube (unscrew or cut).
- Crank the source forward untilit is out of the source tube * (leave the source connected to the drive cable). Enter the area and cover the source with lead shielding being careful not to damage the source.
- Enter the area, remove the lead from the source tube.
- Being careful not to draw the source from the lead shielding, disconnect the source tube from camera.
- Strip the drive cable thru the camera i
(leaving the crank connected).
- Pull the source tube from the drive cable being careful not to pull the source from the shielding.
- Cut the source tube on the camera side of the damaged area, and reconnect the shortened source tube to the camera.
- Pass the drive cable back thru the source tube and camera untilit engages with the cranks.
- Operate the cranks to draw the source from the shielding and into the camera. * (it may be necessary to align the source with the remote longs as it passes thru the open end). CLEAN, REPAlR AND INSPECT ALL EQUIPMENT PRIOR TO RETURNING UNIT TO SERVICE. It is possible (with some cameras) for the source to disconnect during the above operations;if this happens, the remote handling tongs must be used to place the source in a shipping container, j

- c. Source outside the cuide tube (disconnected).
Enter the area and place a shipping container in the source area.
- Enter the area and using remote handling tongs, place the source into the shipping container capsule end first. *
- d. Source outside the cuide tube (connected).
{
This normally occurs if the end cap comes off the guide tube and the source does not stop at the end but continues outside the tube until the control cable discharges all the drive cable. Enter the area and determine the radiation level at the cranks and/or the rear of the exposure device.
- If is it less than 200 mr an hour, the following can be done with less exposure than if shielding is hand I
carried to cover the source. If it is over 200 mr/hr follow the procedures for placing shielding over the source. After each placement of shielding, leave area and READ, RECORD and RECHARGE DOSIMETER prior to continuing. Enter the
)
radiation area and disconnect the drive cable housing at the cranks. *. Enter the.
l I
area and and if the drive cable is present in the housing, pull the source back into the camera. * (If the drive cable is not in the housing, it will be necessary to make a disconnection at the camera and feed the cable back to the hand cranks).
The remote tongs may be required to assist the source as it re enters the source tube.
O'~
e.
Source outside cuide tube (lost or out of siaht).
The first step is to locate the source. This can be accomplished by using a piece of lead one quarter inch thick for iridium, or one half Inch thick for colbatt.
The survey meter is set on a scale where 11 reads less than full scale. A survey is made with the lead placed in front of the survey meter. The direction of the survey (direction indicates a line passing thru the meter and the lead sheel) is changed until a meter drop is indicated. At this point, the source, lead sheet and survey meter are in a line. Using the inverse square law a calculation can be made to determine the approxirnate distance to the source.

After the general direction and distance is calculated, move to another location about the same direction from the source and test for direction again, where theso projected lines would cross will be the general area of the source.
- If the source can be located without difficulty, it can be recovered by using remote handling r
'I tongs. If the source cannot be seen (because of water, mud. grass or other obstructions) keep the area under constant surveillance and call the Radiation Safety Officer and he will make the recovery. These guide lines and procedures will handie most recovery operations. It must be kept in mind no recovery should be attempted by any radiographer unless he has received instructions to do so from the RSO or Manager of NDE Operations. No member of the safety program should attempt a recovery unless he feels his experience, training and is comfortable with the procedure.
if a source must be returned to a camera, and a shipping container is not available, the following procedures can be used.
4 The source is picked up about one inch behind the tip with the remote handling tongs. The hook-up end is fed into the front of the camera and source i
tip is left protruding about one inch. A piece of wood about three or four feet long can be used to lad.(not too hard) the source back into the camera a short distance. Use the remote handling tongs and the front camera plug to push the i
source into the camera, f
