PART 337 PHYSICAL PROTECTION OF CATEGORY 1 AND CATEGORY 2 QUANTITIES OF RADIOACTIVE MATERIAL
SECTION 337.2040 SECURITY ZONES
Section 337.2040 Security Zones
a) Licensees shall ensure that all aggregated category 1 and category 2 quantities of radioactive material are used or stored within licensee-established security zones. Security zones may be permanent or temporary.
b) Temporary security zones shall be established as necessary to meet the licensee's transitory or intermittent business activities, such as periods of maintenance, source delivery and source replacement.
c) Security zones shall, at a minimum, allow unescorted access only to approved individuals through:
1) Isolation of category 1 and category 2 quantities of radioactive material by the use of continuous physical barriers that allow access to the security zone only through established access control points. A physical barrier is a natural or man-made structure or formation sufficient for the isolation of the category 1 or category 2 quantities of radioactive material within a security zone;
2) Direct control of the security zone by approved individuals at all times; or
3) A combination of continuous physical barriers and direct control.
d) For category 1 quantities of radioactive material during periods of maintenance, source receipt, preparation for shipment, installation or source removal or exchange, the licensee shall, at a minimum, provide sufficient individuals approved for unescorted access to maintain continuous surveillance of sources in temporary security zones and in any security zone where physical barriers or intrusion detection systems have been disabled to allow those activities.
e) Individuals not approved for unescorted access to category 1 or category 2 quantities of radioactive material shall be escorted by an approved individual when in a security zone.
