In general, a one year source replacement service contract is to be acquir'd, ir possible.
2.
Yearly service contracts are to be bes* d on the replteament of a 30 curie Iridium sourco four (b) times a year.
The maximum number of curies available at any time for radiograshy will be 36.
3.
If ordering is made on the basis of one source at a time, the maximum quantity to be ordered is to be 30 curies. This allows a 20% error in the production of the source ordered.
4.
The maximum ntttber of curies ctvailable at any one time within plant limits is to be no more than L5 392 R (,

PART II INSPECTIO!! AND MAINTE? LANCE PROGRAM FOR RADIOGRAPHY ECUIPMENT A.
Purpose To establish a procedure for conduccing a designated, periodic inspection of the radiographic equipment, to evaluate extent of wear and necessity for replacement of parts.
B.
Scope This procedure is appl.icable to the maintenance of one (1) Iridium 192 Radiography machine, Model "35" manufac ured by Ge aa Industries, Inc.
C.
Recponsibility of Inspection Personnel qualified to perforn required inspection are as outlined in Part 1, Section C.
D.
The Performance of Inspection Operational inspection checks shall be made daily, 4 hen equipment is in use, to ascertain the proper free working of the following:
(1) Source Lock The source lock key shall be inserted into the key slot.
Key must enter freely and turn one-half turn to allow piston to rise rnd release cource cable. The use of graphite may Le used to lubricate the lock accembly.
Non-conformance of the operating lock will be examined by the company Locksmith and necessary repairs undertaken.
Note:
Care chall be taken that the source chall not be moved fram its shielded position. A survey meter will be used to monitor this operation.
(2) Crank Assembly (a) When the cource cable is fully retracted into the crank assembly, the indicator dial shall be positioned at "O"
feet mark.
Loosen dial cerev and reposition to "O" feet if not in proper position.
(b) Remove the cover cap from the connect-disconnect end and examine threada. Threads chall not be damaced, mashed out of shape or stripped. Damaged threa l end will be replaced with a new part, if necessary.
