Sec. 835.1202  Accountable sealed radioactive sources.

    (a) Each accountable sealed radioactive source shall be inventoried 
at intervals not to exceed six months. This inventory shall:
    (1) Establish the physical location of each accountable sealed 
radioactive source;
    (2) Verify the presence and adequacy of associated postings and 
labels; and
    (3) Establish the adequacy of storage locations, containers, and 
devices.
    (b) Except for sealed radioactive sources consisting solely of 
gaseous radioactive material or tritium, each accountable sealed 
radioactive source shall be subject to a source leak test upon receipt, 
when damage is suspected, and at intervals not to exceed six months. 
Source leak tests shall be capable of detecting radioactive material 
leakage equal to or exceeding 0.005 microcurie.
    (c) Notwithstanding the requirements of paragraph (b) of this 
section, an accountable sealed radioactive source is not subject to 
periodic source leak testing if that source has been removed from 
service. Such sources shall be stored in a controlled location, subject 
to periodic inventory as required by paragraph (a) of this section, and 
subject to source leak testing prior to being returned to service.
    (d) Notwithstanding the requirements of paragraphs (a) and (b) of 
this section, an accountable sealed radioactive source is not subject to 
periodic inventory and source leak testing if that source is located in 
an area that is unsafe for human entry or otherwise inaccessible.
    (e) An accountable sealed radioactive source found to be leaking 
radioactive material shall be controlled in a manner that minimizes the 
spread of radioactive contamination.
