Section 0400-20-08-.06 - PRECAUTIONARY PROCEDURES IN RADIOGRAPHIC OPERATIONS(1) Security. During each radiographic operation the radiographer, or the other individual present, as required by subparagraph (4)(a) of Rule 0400-20-08-.05, shall maintain continuous, direct, visual surveillance of the operation to protect against unauthorized entry into a high radiation area as defined in Chapter 0400-20-05 except at permanent radiographic installations where all entryways are locked and the requirements of paragraph (9) of Rule 0400-20-08-.04 are met.
(2) Posting. Areas in which radiography is being performed shall be conspicuously posted according to the standards set out in Chapter 0400-20-05, without exceptions.
(3) Radiation surveys and survey records. (a) The licensee or registrant shall ensure that at least one calibrated and operable radiation survey instrument is available:1. At the location of its radiographic operations; and2. At the storage area, as defined in Rule 0400-20-08-.03, whenever a radiographic exposure device, a storage container or source is being placed in storage.(b) After each exposure, the licensee or registrant shall ensure that a survey with a calibrated and operable radiation survey instrument is made to determine that the sealed source has been returned to its shielded position or that the radiation from the radiation machine has been terminated. The entire circumference of the radiographic exposure device shall be surveyed. If the radiographic exposure device has a source guide tube, the survey shall include the guide tube. The survey shall determine that the sealed source has returned to its shielded position before exchanging films, repositioning the exposure head or dismantling equipment.(c) Any time the source is exchanged and whenever a radiographic exposure device is placed in a storage area, the licensee shall ensure that a survey with a calibrated and operable radiation survey instrument is made to determine that the sealed source is in its shielded position. The entire circumference of the radiographic exposure device shall be surveyed. The results of the last storage survey of the workday, required by this subparagraph, shall be recorded and retained for 3 years.(d) Records shall be kept of the duration of each radiographic exposure and the number of exposures made. In addition, for each radiographic exposure employing a radiation machine the voltage and current used shall be noted. These records shall be maintained for 3 years for inspection by the Division and for field work may be kept on the area survey form.(e) Each licensee or registrant conducting industrial radiography at a temporary job-site shall have the following documents available at that site for inspection by the Division: 1. Appropriate license or registration; .2. Operating and emergency procedures;3. Applicable regulations;4. Survey records required pursuant to this rule and Chapter 0400-20-05 for the period of operation at the site;5. Daily pocket dosimeter records for the period of operation at the site; and6. The latest instrument calibration and leak test records for specific devices in use at the site. Acceptable records include tags or labels that are affixed to the device or survey meter.(4) Radiation surveys.(a) Conduct surveys with a calibrated and operable radiation survey instrument that meets the requirements of paragraph (4) of Rule 0400-20-08-.04.(b) Using a survey instrument meeting the requirements of subparagraph (a) of this paragraph, conduct a survey of the radiographic exposure device and the guide tube after each exposure when approaching the device or the guide tube. The survey shall determine that the sealed source has returned to its shielded position before exchanging films, repositioning the exposure head, or dismantling equipment.(c) Conduct a survey of the radiographic exposure device with a calibrated radiation survey instrument any time the source is exchanged and whenever a radiographic exposure device is placed in a storage area (as defined in Rule 0400-20-08-.03, to ensure that the sealed source is in its shielded position.(d) Maintain records in accordance with Rule 0400-20-08-.15.Tenn.
