Sec. 34.23  Locking of radiographic exposure devices, storage containers 
and source changers.

    (a) Each radiographic exposure device must have a lock or outer 
locked container designed to prevent unauthorized or accidental removal 
of the sealed source from its shielded position. The exposure device 
and/or its container must be kept locked (and if a keyed-lock, with the 
key removed at all times) when not under the direct surveillance of a 
radiographer or a radiographer's assistant except at permanent 
radiographic installations as stated in Sec. 34.51. In addition, during 
radiographic operations the sealed source assembly must be secured in 
the shielded position each time the source is returned to that position.
    (b) Each sealed source storage container and source changer must 
have a lock or outer locked container designed to prevent unauthorized 
or accidental removal of the sealed source from its shielded position. 
Storage containers and source changers must be kept locked (and if a 
keyed-lock, with the key removed at all times) when containing sealed 
sources except when under the direct surveillance of a radiographer or a 
radiographer's assistant.
