64E-5.1319. Contamination Control Program

The licensee shall establish and submit for department approval a contamination control program to limit the spread of unsealed sources of radioactive materials. This program shall include contamination action levels, corresponding actions taken if these levels are exceeded, frequency of measurement and maintenance of records.

(1) Unless otherwise specified in the license, the licensee shall perform the following:

(a) A survey with a radiation survey instrument shall be completed at the end of each day of use or receipt of all areas where radioactive materials are used or received.

(b) A weekly survey with a radiation survey instrument shall be completed of all areas where radioactive materials or radioactive waste are stored.

(c) A wipe survey shall be completed for removable contamination weekly during weeks of use of all areas where radioactive materials or waste are routinely used or stored.

(d) Surveys required by (1)(a), (b) and (f) of this section shall be completed with an instrument capable of measuring dose rates as low as 0.1 millirem (1 µSv) per hour, if applicable.

(e) A wipe survey shall be completed for removable contamination at the end of each day of use of all areas where radioactive materials are routinely used if the radioactive materials authorized by the license are not detectable with instruments described in (1)(d) above.

(f) Monitoring shall be performed of individuals for contamination prior to leaving the restricted area.

(g) The radiation safety officer shall be notified if the contamination detected during the surveys required by this section exceeds the action levels specified in (2), below.

(2) Unless otherwise specified in the license, the licensee shall take the following actions if the corresponding action levels are exceeded:

(a) Follow decontamination procedures and resurvey to determine effectiveness of decontamination efforts if the action levels are exceeded when conducting surveys described in (1)(a), (b) or (f) above;

(b) Follow emergency procedures if the radiation detected during the survey required in (1)(f) of this section is above action levels; and

(c) Follow decontamination procedures and resurvey to determine effectiveness of decontamination efforts if the action levels listed below are exceeded for the survey required in (1)(c) or (e) above;

1. 100 dpm per 100 square centimeters of any alpha-emitting radioactive materials not listed in this section;

2. 1,000 dpm per 100 square centimeters of any beta- or gamma-emitting radioactive materials not listed in this section;

3. 50 dpm per 100 square centimeters of any transuranic;

4. 2,000 dpm per 100 square centimeters of any uranium; or

5. 2,000 dpm per 100 square centimeters of any radioactive material with a half-life of less than 80 hours.

(3) The licensee shall retain a record of each survey required by this section for 3 years. These records shall include:

(a) The date of the survey;

(b) An annotated diagram of each area surveyed;

(c) Background levels;

(d) Measured dose rates, keyed to the diagram, expressed in millirem (microsieverts) per hour or the removable contamination, keyed to the diagram, expressed in dpm per 100 square centimeters, or counts per minute if performed with a radiation survey instrument, with the action level described in (2)(a) of this section;

(e) The serial number and model number of the instrument used to make the survey or analyze the samples; and

(f) The initials of the person who performed the survey.

(4) Records of surveys described in (1)(f) need not be recorded unless the action level described in (2)(a) of this section is exceeded.
