Enclosed please. find seven (7) copies of our Quality _
Assurance Program -(Section. B of our manual).
This basic program has 'been'-in. effect' since June,.1974.
The latest revision, -(C),
has 'been -initiated to-incorporate some of. the requirements of
~
10CFR Part :71 not previously included in our manual._ _ _
Our Radiography Manual is in two sections:
Section A contains cur " Operating and Emergency Procedures-Instructions _
to Radiography Personnel."- This section is provided to each member of our radiographic department and is one of the basic tools for their initial training.
Section B is " Management Responsibilities and Information Relating to the Radiographic._
Quality _ Assurance _ Program _"--_ This is the section forwarded - for L your distribution.
All chapters of Section B are, and -have been c

MANAGEMENT RESPONSIBILITIES AND INFORMATION RELATING TO THE RADIOGRAPHIC QUALITY ASSURANCE PROGRAM Policv:
It is the policy of WALWORTH COMPANY-Columbus Plant to perform Inductrial Radiography conforming in all respects to the applicable requirements of the -United States Nuclear Regulatory Commission, Title 10, Chapter 1, Code of Federal Regulations-Energy, Rules and Regulations.
Conformance to these regulations must be achieved through the ef forts of all individuals up to and including plant management.
A formal program for the control and assurance of radiographic operations has been established at my direction and is in effect.
It is a basic management policy that the decision making function on the acceptance of quality in regard to ecuipment and safety shall be independent of the authority of those responsible for production.
The established program for the control and assurance of RADIATION SAFETY has been recorded in this section of the manual which has my full endorsement and support.

Determine the source activ. tty from the decay chart and calculate the radiation level at one foot from the source.
For Radium:
R/Hr. output at one foot = 9 x source strc: 7th in curies.
For Cobalt 60:
R/Hr. output at one foot =14.5 x source strength in curies.
For Iridium 192:
F/Hr. output at one foot = 5.9 x cource strength in curies.
2.
After determining the radiation output at one foot from the source, use the inverse square law for reduction of radiation intensity to calculate the distance required to reduce the intensity to each of the specified levels.
(Readings A thru F or G, H,
J and K as applicable).

XII RECEIPT, CHANGING, DISPOSAL OF SOURCES a.
The shield contains a lead filled steel shell to shield the gamma ray emitting source.
A stainless steel source tube is located in the lead and serves as a conducting path to the shielding center.
The outlets of the "U"
tube are on the top surface of the shield and there is a stop midway in its length permitting use of two source cables at one time.
b.
The closure mechanism consists of two screw caps with hold down rods attached.
These caps screw onto bushings directly over the tube outlet and hold the source cable
~
connector plug firmly in place, precluding movement of the source from its safe position within the lead shield.
6.1.1 A Technical Operations Model 416 Source Changer shall be used for storage of either an Iridium or Cobalt source.
6.1.2 OPERATION
a.
Unlock, cut tamper-proof seal,' remove screws and open cover.
Remove cap marked (A) and affix open end of snout tube to threaded bushing.
DO NOT remove cap with tag, until old source is deposited in shield.
b.
Retire to safe distance and crank out old source into source changer.
Detennine by monitor dhat old source isltuated completely within source changer.
c.
Lift spring loaded guide tube, directly below bushing exposing connector of source cable and control cable.
With tool provided, raite spring on connector to allow removal of source cable end from connector.
This is acccmpished by pulling apart while holding spring up.
EQ NOT withdraw source cable.
Remove snout cable from threaded bushing.
Replace cap securely on bushing.
d.
Remove cap marked (B).
Screw snout cable on threaded bushing.
Raise spring loaded guide tube below bushing and connect ends of cables by inserting source cable end into control cable connector.
Make very certain connection is comolete.
Retire to safe distance.
Crank new source into safe position as indicated on control box.
Monitor the source changer, the guide tube, and the source container as routine precaution.

(A) 6.2 The Technical Operations Model 650 Source Changer con-sists of two assemblies:
a.
The shield contains depleted Uranium (U238) covered by a steel shell.
A stainless steel source tube is located in the depleted Uranium and serves as a conducting path to the shielding center.
The out lets of the "U"
tube are on the top surface of the shield and there is a stop midway in its length permitting use of two source cables at one time.
b.
The closure mechanism consists of a hold down cap which fits over the two source chambers and screws directly into the steel housing.
The hold down cap keeps the source cable connectors firmly in place, precluding movement of the source from its safe position within the depleted Uranium shield.
6.2.1 OPERATION
a.

Disconnect guide tube from changer and prepare container for shipment.
IMPORTANT:
Replace snout switch to open end of source guide tube.
6.3 SAFETY
6.3.1 The source changer has been designed to come well within the minimum requirements of radiation safety.
The only time that excessive radiation does exist,
is during the transfer of a source from the source changer to the source changer.
Adequate distance from the exposed source to areas where personnel have access must be maintained.
It should be under-stood that transfer of a source is in reality the same as maki_ng an exposure.and the game safety measures should be followed.
(C) 7.0 DISPOSAL OF SOURCES:
7.1 Prior to shipment of a source (s) back to Technical Operations, the following stepu must be taken:
a.
Make certain the " Hold-down" cap on the closure mechanism is secure, affix the tamper-proof seal and inspect to make sure the source identification tag is properly attached.
b.
Survey the shipping container to determine the radiation levels at the surface and at a distance of three feet from the container.
The readings must fall within the limitations as stated in paragraph 5.3 of this chapter.
c.
Record the readings in mr/hr at three feet on each
" Radiation Label" in the "Index Number" block.
Record the same reading plus the surface reading on the Decay chart.
