y R 7.2 Procedure for Uniondina the Packaue i-HOTES: a. A= radioactive material. package must be accepted from the carrier at the time it is delivered. e b'. If a' radioactive material package is to be held at the carrier's terminal for pickup, arrangements must be'made to receive notification from the carrier of the arrival of the package at the time of arrival. The package must be picked up expeditiously upon receipt of notification (within three hours if prac-ticable). l. Upon receipt of a package of radioactive material, survey the exterior surfaces of the package and assure that the maximum radiation level does not exceed 200 mrem /hr. . Survey three feet from the exterior surfaces of the packages and assure that the maximum radiation level does not exceed 10 mrem /hr. If either of these limits are exceeded, notify the Radiation Safety of fi-cer immediately.. Record the maximum radiation levels measured at the package surface and at three feet from the package surface on the Receiving Report. 2. If the package contains radioactive material which is not in special form make a contamination wipe test of the exterior surface of the package. Wipe h represen-tative surface of the package, covering an area of approximately 100 square centimeters, using a cloth patch and moderate pressure. Measure the activity of the patch using the contamination monitor and assure that the activity does not exceed 0.01 microcurie. If this limit is exceeded, notify the Radiation Safety Officer immediately. Record the results of this con-tamination wipe test on the Receiving Report. Note: If any of these limits are exceeded, the Radiation Safety Officer shall immediately notify the USNRC and the final delivering carrier. 3. Inspe-t the package for any evidence of physical dam-age. Record the results of this inspection on the Receiving Report. Also record on the Receiving Report the source model number, source serial number, radionu-clide, activity, transport package model number and package serial number. Forward-a copy of the completed Receiving Report to the Radiation Safety Officer. 7-6 Revision 1 1 October 1990 a i
\\ ' '; ;; 4. Assure _that the. package is locked, or place the package I into an outer locked container. Place the. package into the Radioactive Material Storage Room and lock the door to the room. ] 5. Keep a copy of the Operations Manual for the package on file to assure you have the proper opening instruc-1 tions. 6. To properly open and use the package, as a radiographic source changer refer to the detailed instruction manual for this device. k b l l t i l. \\; 1 7-7 Revision 1 October 1990
b [ 1a, 7.3 Procedure for PreDaration of an Emotv Packnae for Transport u 1. For shipment of an empty Model 820 source changer, first assure the changer does not contain an unauthorized source or cropped source by performing a physical certification using the following procedure. NOTE: Use only the gauge provided with source changer. Do e not use any other tool or a gauge for another device. If.you do not have the proper gauge to perform the test, contact Amersham corporation before conducting the test. a. Insert the' proper gauge in the empty tube (s) of the source changer. Read the gauge at the top of the outlet fitting. b. The gauge should bottom out in the empty source tube and indicate a safe condition (green signal). Verify that each empty tube indicates a safe condition and proceed to step 2. c. If the gauge indicates an unsafe condition (red sig-nal) there may be an obstruction in the tube. Remove the gauge slowly while observing the survey meter. If the. radiation levels increase as the gauge is being L removed keep the gauge within the device, secure the L device and contact Amersham for further instructions. If the radiation levels remain normal as the gauge is l being removed, completely. remove gauge and contact Amersham corporation for shipping instructions, d. When you have assured the container is empty, attach empty tag to source changer, insert shipping plugs. Install the shipping cover, secure with the 8 bolts and I seal wire with a securing seal through the drilled head i of 2 of the bolts. l i. 2. If the shipping package is to be placed inside a crate l or other outer packaging, the outer packaging must be strong enough to withstand the normal conditions-of l transport and must not reduce the safety of the pack-age. The shipping package must be placed within the outer package with sufficient blocking to prevent shifting during transportation. NOTE: When using a crate or other outer packaging to ship the 820, steps 3-4 refer to the crate or outer packaging. l 7-8 Revision 1 October 1990 l
l.:... 3.. Assure-that the levels of removable radioactive contamination on the outside surface of the outer package do l not exceed 0.001 microcurie per 100 square centimeters. 4. Survey the package at the surface and at one meter from the surfact to determine the proper shipping labels to be applied to package. a. If the surface radiation level does not exceed 0.5 mren/hr and there is no measurable radiation level at one meter from the surface, no label is required. Mark the outside of the package with the proper shipping. name and identification number (Radioactive Material, Articles Manufactured from depleted Uranium, UN 2909) and the statement ~ " EXEMPT FROM SPECIFICATION PACKAGING SHIPPING PAPER AND CERTIFICATION, MARKING AND LABELING AND EXEMPT FROM THE REQUIREMENTS OF 49CFR part 175 PER CFR173.421-1 AND 49 CFR173.424." NOTE: This does not exempt the shipment from the reporting requirements listed in 49 CFR parts 171-177 pertain-ing to the reporting of the contamination or other radiation incidents. Additionally, a notice must be enclosed in or on the package, included with the packing list or otherwise forwarded with the package. The notice must include the name of the consignor or consignee and the state-ment: "This package conforms to the conditions and limita-tions specified in 49CFR173.424 for Exempted Radioac-tive Material, Manufactured from Depleted Uranium, UN 2909." b. If the surface radiation level exceeds 0.5 mrem /hr, or-if there is a measurable radiation level at one meter from the surface, use the criteria of table 1 in sec-tion 7.1 to determine the proper shipping labels to be applied to the package with the proper shipping name and identification number (Radioactive Material, LSA, n.o.s., UN 2912). If the container is packaged inside a crate or other outer packaging, mark the package with the statement "INSIDE PACKAGE COMPLIES WITH PRESCRIBED SPECIFICATIONS". Properly complete the shipping papers, as listed in section 7.1. The isotope is U-238 and approximately 18 millicuries. 7-9 Revision 1 October 1990
