Sec. 39.31  Labels, security, and transportation precautions.


    (a) Labels. (1) The licensee may not use a source, source holder, or 
logging tool that contains licensed material unless the smallest 
component that is transported as a separate piece of equipment with the 
licensed material inside bears a durable, legible, and clearly visible 
marking or label. The marking or label must contain the radiation symbol 
specified in Sec. 20.1901(a), without the conventional color 
requirements, and the wording ``DANGER (or CAUTION) RADIOACTIVE 
MATERIAL.''
    (2) The licensee may not use a container to store licensed material 
unless the container has securely attached to it a durable, legible, and 
clearly visible label. The label must contain the radiation symbol 
specified in Sec. 20.1901(a) of this chapter and the wording ``CAUTION 
(or DANGER), RADIOACTIVE MATERIAL, NOTIFY CIVIL AUTHORITIES (or NAME OF 
COMPANY).''
    (3) The licensee may not transport licensed material unless the 
material is packaged, labeled, marked, and accompanied with appropriate 
shipping papers in accordance with regulations set out in 10 CFR part 
71.
    (b) Security precautions during storage and transportation. (1) The 
licensee shall store each source containing licensed material in a 
storage container or transportation package. The container or package 
must be locked and physically secured to prevent tampering or removal of 
licensed material from storage by unauthorized personnel. The licensee 
shall store licensed material in a manner which will minimize danger 
from explosion or fire.
    (2) The licensee shall lock and physically secure the transport 
package containing licensed material in the transporting vehicle to 
prevent accidental loss, tampering, or unauthorized removal of the 
licensed material from the vehicle.
