i 71-9024 Enc 1 to ltr dtd: OCT 11 1000 Qf1 RATING PROCEDURES '1. ' Revise-the operating procedures to address the steps to be taken in preparing the isotope exposure device for shipment. As a minimum, these steps should include verification that the Ir-192. isotopic source is in the shielded position, the exposure device is locked and the shipping l plug is installed. If the exposure device is to be shipped without the Ir-192 isotopic 1 source,'the operating procedures should also include the specific tests or measu.ements that will be made prior to each shipment of an empty d exposure device to assure that the exposure device is empty. The tests or measurements should be capable of detecting the presence of a source l assembly, even if the cable (pigtail) has been removed or shortened. 2. Revise the operating procedures to assure that prior to each shipment the package external. dose rates and surface contamination levels are within J the limits prescribed by 10 CFR 671.47 and 10 CFR 671.87. l 3. Revise the operating procedures to include the a> plication of a tamper l indication feature as required by 10 CFR 671.43()). i 4. In' steps-3 and 7 of the operating procedures, it is not clear whether the l " source" to be placed in the canister refers to the exposure device or to the Ir 192 isotopic source. Revise the operating procedures to clarify l this ambiguity. 1 l MAINTENANCE PROGRAM Revise the maintenance program to include periodic inspection of the isotope exposure device. e I i P l l 4}}
