CHAPTER V - SOURCE PROCUREMENT AND
ACCOUNTABILITY
5.1 Ordering Radioactive
Material
The Advantage System is used for purchasing radioactive
material at ASU. Purchasing Department personnel obtain approval
for these purchases either on-line, or through written approval on
hard copies of the requisition. To process orders for radioactive
material:
- Complete information using Advantage - use object code 7320
10 for radioactive material;
- Specify, in the appropriate space, that delivery is to be
made to the ORS;
- Describe the item(s) in terms of the nuclide, the
chemical/physical form of the nuclide, and the activity in uCi
or mCi.
5.1.1 Procurement Other than by Purchase Order
Radioactive material in any quantity must not be obtained for
use at ASU without approval of the ORS. Before arrangements are
made with organizations or individuals to obtain radioactive
material, the organization or person from which the material is
obtained must have certification from the ORS that ASU is licensed
to receive it. The ORS is responsible to see that DOT and NRC
regulations are adhered to with respect to transport and receipt
of the source.
5.1.2 Receipt of Radioactive Material
All radioactive material shipped to ASU facilities is sent to
the ORS. Upon receipt of radioactive material, ORS staff survey
material for radiation levels and surface contamination.
The responsible user is notified of its arrival. Radioactive
material is delivered to users by ORS staff.
5.2 Transfer of Radioactive
Material to Other Users at ASU
Transfer of radioactive material between sub-licensees at ASU
must be approved by the RSO prior to transfer of the material.
5.3 Radioactive Material
Accountability
5.3.1 Source Control Number
Each vial or source containing radioactive material is given a
Source Control Number (SCN) at the time it arrives at ASU. The SCN
assists users in tracking down information on orders and keeping
track of material in each laboratory.
A "Source Utilization Log" is issued to users for each vial of
consumable radioactive material when it is delivered by ORS
personnel. The log is updated by the user when radioactive
material is disposed of as waste. The log remains in the
possession of the user until all of the radioactive material in
the vial has been disposed of, at which time the log is returned
to the ORS. These records must be maintained in the laboratory to
assist in keeping track of radioactive material in work areas, and
be available for review by ORS personnel and/or state inspectors
and auditors. All entries should be as accurate as possible, but
may be conservative estimates when exact quantities are not known.
Logs may be corrected for radioactive decay at the discretion of
the sub-licensee.
5.3.2 Quarterly Radioactive Source Inventory
At the end of each calendar quarter, a computer printout with a
list of radionuclide sources in the possession of the user is sent
to each sub-licensee. Sources are identified by source number,
radionuclide, and chemical/physical form.
A physical check must be conducted by the sub-licensee for all
radioactive material. Sources in possession of the user which are
not listed on the printout, or sources listed which are not in the
possession of the user, must be brought to the attention of the
RSO. The activity of sources on hand should be checked and
corrected if there are changes due to disposal or decay.
