This notice must include the name of the consignor or consignee and the state-ment:
"This package conforms to the conditionr, and limita-tions specified in 49 CFR173.424 for excepted radioac-
.tive material, articles manufactured from depleted uranium UN 2909.
15.
Place the package on o the vehicle using slings or hooks through the eyebolts of the source changer.
16.
Properly brace and secure the package against movement in the vehicle.
17.

NOTE:1.
For air shipments, the following Shipper's Certifi-cation may be used:
"I hereby certify that the centents of the consignment are fully and accurately described above by proper shipping name and are classified packaged, marked and labeled and are in proper condition for carriage by air according to applicable national governmental regula-t tions."
2.
Foi air shipments, the package must be LTbeled with a
" CARGO AIRCRAPT ONLy" label and the s..4pping papers must state:

7.2 procedure for Unloading the Package NOTE:
a.
A radioactive material package must be accepted from the carrier at the time it is delivered.
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 expedi-tiously upon receipt of notification (within three hours if practicable).
1.
Upon receipt of a package of radioactive material, survey the exterior surf aces 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 mrom/hr.
If either of these limits are exceeded, notify the Radiation Safety Of ficer 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 surf ace of the package.
Wipe a representative 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 contamination wipe test on the Receiving Report, i
Note: If any of these limits are exceeded, the Radiation Safety Officer shall immediately notify the USNRC' and
/
the final delivering carrier.
l 3.
Inspect the package for any evidence of physical damage, j
Record the results of this inspection on the Receiving Report.. Also record on the Receiving Report the p arce i
model number, source serial number, radionuclide, activity, i'
transport package model number and package serial number.
Forward a copy of the completed Receiving Report to the Radiation Safety Officer.
4.
Assure that the package is locked, or place the package into
{
an outer locked container.
Place the package into the l
Radioactive Material Storage Room and lock the door tc the room.
l 5.
Keep a copy of the Operations Manual for the package on file to_ assure you have the proper opening instructions.

Assurc that the package does not contein a radioactive source.
2.
If the shipping package is to be placed inside a crate or other outer packaging, the outer packaging 'must be strong enough to withstand the normal conditions of. transport and must not reduce the safety of the package.
The shipping package must be placed within the outer package with suffi-cient blocking to prevent shifting during transportation.
3.
Assure that the levels of removable radioactive contamination on the outside surface of the outer package do not exceed 0.001 microcurie per 100 square centimeters.
4.
Survey the package at the surface and at one meter from the surface to determine the proper shipping labels to be applied to package.
a.
If the surface radiation level does not exceed 0.5 mrem /hr and there is no measurable radiation level at one meter from the surface, nc label is required.
Mark the outside of the package with the proper shipping name and identification number (Radioactive Material, Articles Manuf actured from depleted Uranium, UN 2009) and the statement " EXEMPT FROM SPECIFICATION PACKAGING l
SHIPPING PAPER AND CERTIFICATION, MARKING AND LABELING l
AND EXEMPT FROM THE REQUIREMENTS OF 49CFR part 175 PER CFR173.421-1 AND 49 CFR173.424".
Additionally, a notice must be enclosed in er 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-E mont:
"This package conforms to the conditions and limita-tions specified in 49CFR173.424 for Exempted Radioac-tive Material, Articles Manufactured from Depleted Uranium, UN 2909".
I b.
If the surfaco 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 ser-tion 7.1 to determine the proper shipping labels to be l

SECTICN 8 ACCEPTANCE TESTS AND MAINTENANCE PROGRAM 8.1 Acceptance Tests 8.1.1 Visual Inspection The package is visually inspected to assure 1.
It was constructed properly in accordance with drawing number 82090.
2.
The labels are inspected to assure they contain the required information as referenced in section 7.
3.
All fasteners (screws) as required by drawing number 82090 are installed.
l The source assembly used in this device is visually inspect-ed to assure proper closure of the weld, to maintain primary containment.
It is also inspected for proper length to assure it locks in the required storage position.
B.1.2 Structural and Pressure Tests The swage coupling between the source capsule and cable is sub-jected to a static tensile test with a load of 100 pounds.
Failure of this test will prevent the source assembly from being used.
8.1.3 Leak Tests The radicactive source capsule (the primary containment)' is wipe tested for leakage of ladioactive contamination.
The source a
capsule is subjected to a vacuum bubble leak test.
The capsule is then subjected to a second wipe test for leakage of radioac-tive contamination.
The contamination must be less than 0.005 microcuries.
Failure of any of these tests Nill prevent use of this source assembly.
The package is wipe tested on the exterior surface prior to its first shipment in accordance witg 10CFR71.87.
(If this wipe test exceeds 0.001 microcuries/100 cm it wi:1 not be shipped.)
8.1.4 Component Tests The lock cssembly of the package is tested to assure that security of the source will be maintained.
Failure of this test will prevent use of the package until the lock assembly is cor-1ected and retested.
8.1.5 Tests for Shielding Integrity The radiation levels at the surface of the package and at one I
8-1 Revision 1 April 1990 f
meter from the surf ace are measured using a small detector survey instrument (e.g.,
A14/PDR-27).
'These radiation levels, when extrapolated to the rated capacity of the package and a surf ace correction factor applied as outlined in Amersham's Quality Inspection Procedure, must not exceed 200 milliroentgens per hour at the surf ace nor ten milliroentgens per hour one meter from the surface of the package.
Failure of this test will prevent use of the package.
