R313-12-51. Records

  (1) A person who receives source or byproduct material pursuant to a license issued pursuant to the regulations in this part shall keep records showing the receipt, transfer, and disposal of this source or byproduct material as follows:

  (a) 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.

  (b) The licensee who transferred the material shall retain each record of transfer of source or byproduct material until the Director terminates each license that authorizes the activity that is subject to the recordkeeping requirement.

  (c) The licensee shall retain each record of disposal of source or byproduct material until the Director terminates each license that authorizes the activity that is subject to the recordkeeping requirement.

  (d) 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 Section R313-12-51 account for 100 percent of the material received.

  (2) The licensee shall retain each record that is required by Section R313-12-51 or by license condition for the period specified by the appropriate rule or license condition. If a retention period is not otherwise specified by rule or license condition, each record must be maintained until the Director terminates the license that authorizes the activity that is subject to the recordkeeping requirement.

  (3) A licensee or registrant shall maintain records showing the receipt, transfer, and disposal of all sources of radiation.

  (4) Prior to license termination, each licensee authorized to possess radioactive material with a half-life greater than 120 days, in an unsealed form, may forward the following records to the Director:

  (a) records of disposal of licensed material made under Sections R313-15-1002 (including burials authorized before January 28, 1981), R313-15-1003, R313-15-1004, and R313-15-1005; and

  (b) records required by Subsection R313-15-1103(2)(d).

  NOTE: 10 CFR 20.304 permitted burial of small quantities of licensed materials in soil before January 28, 1981, without specific U.S. Nuclear Regulatory Commission authorization. See 20.304 contained in the 10 CFR, parts 0 to 199, edition revised as of January 1, 1981.

  (5) If licensed activities are transferred or assigned in accordance with Subsection R313-19-34(2), each licensee authorized to possess radioactive material, with a half-life greater than 120 days, 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:

  (a) records of disposal of licensed material made under Sections R313-15-1002 (including burials authorized before January 28, 1981), R313-15-1003, R313-15-1004, R313-15-1005, and R313-15-1008; and

  (b) records required by Subsection R313-15-1103(2)(d).
