CPS No. 1907.20 1.0 PURPOSE

~

To establish the necessary controls for the possession of radioactive sources.

2.0.

DISCUSSION / DEFINITIONS' 2.l~

Discussion Controls are required for radioactive sources due to their radioactive nature and the. requirements of regulatory agencies.

These controls include accountability, inventory, leak testing, and activity t;.

calculations.

2.2 Definitions 2.2.1-Byproduct Material - Any radioactive 3j material (excluding Special Nuclear

.i-Material (SNM)) yielded in or made l.

radioactive by exposure to the radiation t L incident to the process of producing or j

-[

utilizing SNM.

use, transfer, or ownership.

general license for receipt, possession,.

2.2.3 Exempt Quantity of' Byproduct Material -

-l That amount of Byproduct Material which is less than the values stated in 10CFR30.70 or 10CFR30.71.

x"

2. 2.- 4

.Non-exempt material That quantity of.

material that requires a. specific, license for receipt, possession, use, transfer, or

' ownership.

This may also include material received under a General License, t

2.2.5 Sealed Source - radioactive material (liquid or solid) that is permanently g

bonded, fixed or contained, in a manner designed to prevent release and dispersal of the radioactive material under the most severe conditions,'which are likely to be encountered in normal use and handling.

8.1 Accountability 8.1.l~

Upon receipt or production of a radioactive source, initiate accountability as;follows:

NOTE In-house production of a radioactive source meeting the requirements of Section 8.3 for leak testing shall be entered into surveillance tracking in accordance with CPS No. 1011.02, SURVEILLANCE TESTING.

..]

1-8.1.1.1 Non-exempt Byproduct Material - Initiate CPS No. 1907.20F001, RADIOACTIVE SOURCE RECORD and retain the RADIOACTIVE SOURCE RECORD in the Non-exempt Source Binder.

Enter the material into the Source Tracking Book.

8.1.1.2 Exempt Byproduct Material - Enter the l~

material into the Source Tracking Book.

I 8.1.2 Place the material in an approval storage f(

location and update the source inventory record at the storage location.

8.1.2.1 Sources temporarily removed from their

?

storage location (less than one day) need only an entry made on the source inventory record to denote its location.

8.1.2.2 Sources permanently removed require.an entry in~the Source Tracking Book and source inventory record to denote the new location. -Update to source inventory record at the new location.-

p 8.1.3 Receipt of a liquid radioactive source shall also require the initiation of CPS No. 1930.01F002, CONTROLLED SUBSTANCE ACCOUNTABILITY RECORD.
