records

[[Page 643]]

showing the receipt, transfer, and disposal of this source or byproduct 
material as follows:
    (1) The licensee shall retain each record of receipt of source or 
byproduct material as long as the material is possessed and for three 
years following transfer or disposition of the source or byproduct 
material.
    (2) The licensee who transferred the material shall retain each 
record of transfer or source or byproduct material until the Commission 
terminates each license that authorizes the activity that is subject to 
the recordkeeping requirement.
    (3) The licensee shall retain each record of disposal of source or 
byproduct material until the Commission terminates each license that 
authorizes the activity that is subject to the recordkeeping 
requirement.
    (4) If source or byproduct material is combined or mixed with other 
licensed material and subsequently treated in a manner that makes direct 
correlation of a receipt record with a transfer, export, or disposition 
record impossible, the licensee may use evaluative techniques (such as 
first-in-first-out), to make the records that are required by this part 
account for 100 percent of the material received.
    (b) The licensee shall retain each record that is required by the 
regulations in this part or by license condition for the period 
specified by the appropriate regulation or license condition. If a 
retention period is not otherwise specified by regulation or license 
condition, each record must be maintained until the Commission 
terminates the license that authorizes the activity that is subject to 
the recordkeeping requirement.
    (c)(1) Records which must be maintained pursuant to this part may be 
the original or reproduced copy or microform if the reproduced copy or 
microform is duly authenticated by authorized personnel and the 
microform is capable of producing a clear and legible copy after storage 
for the period specified by Commission regulations. The record may also 
be stored in electronic media with the capability for producing legible, 
accurate, and complete records during the required retention period. 
Records such as letters, drawings, specifications, must include all 
pertinent information such as stamps, initials, and signatures. The 
licensee shall maintain adequate safeguards against tampering with and 
loss of records.
    (2) If there is a conflict between the Commission's regulations in 
this part, license condition, or other written Commission approval or 
authorization pertaining to the retention period for the same type of 
record, the retention period specified in the regulations in this part 
for such records shall apply unless the Commission, pursuant to 
Sec. 40.14 of this part, has granted a specific exemption from the 
record retention requirements specified in the regulations in this part.
    (d) Prior to license termination, each licensee authorized to 
possess source material, in an unsealed form, shall forward the 
following records to the appropriate NRC Regional Office:
    (1) Records of disposal of licensed material made under Sec. 20.2002 
(including burials authorized before January 28, 1981 \1\), 20.2003, 
20.2004, 20.2005; and
---------------------------------------------------------------------------

    \1\ A previous Sec. 20.304 permitted burial of small quantities of 
licensed materials in soil before January 28, 1981, without specific 
Commission authorization. See Sec. 20.304 contained in the 10 CFR, parts 
0 to 199, edition revised as of January 1, 1981.
---------------------------------------------------------------------------

    (2) Records required by Sec. 20.2103(b)(4).
    (e) If licensed activities are transferred or assigned in accordance 
with Sec. 40.41(b), each licensee authorized to possess source material, 
in an unsealed form, shall transfer the following records to the new 
licensee and the new licensee will be responsible for maintaining these 
records until the license is terminated:
    (1) Records of disposal of licensed material made under Sec. 20.2002 
(including burials authorized before January 28, 1981 \1\), 20.2003, 
20.2004, 20.2005; and
    (2) Records required by Sec. 20.2103(b)(4).
    (f) Prior to license termination, each licensee shall forward the 
records required by Sec. 40.36(f) to the appropriate NRC Regional 
Office.
