Section 144-220-E-D-19 - Radiation surveysThe licensee shall:
A. Not conduct a radiographic operation unless calibrated and operable radiation survey instrumentation as described in E.8 is available and used at each site where radiographic exposures are made.B. Use a survey instrument that meet the requirements of E.8.A.-C. of this Part, to conduct a physical survey of the entire circumference of the radiographic exposure device and the guide tube after each exposure when approaching the device or the guide tube. The survey must 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 E.3) to ensure that the sealed source is in its shielded position.D. Post potential radiation areas where industrial radiographic operations are to be performed in accordance with E.22, based on estimated dose rates, before industrial radiographic operations begin. An area survey shall be performed during the first radiographic exposure to confirm that E.22 requirements have been met and that unrestricted areas do not have radiation levels in excess of the limits specified in Part D.E. Meet the requirements of paragraph D of this section, each time re-establishment of the restricted area is required. The requirements of E.19.E do not apply to pipeline industrial radiographic operations when the conditions of exposure including, but not limited to, the radiographic exposure device, duration of exposure, source strength, pipe size, and pipe thickness remain constant.F. Perform a lock-out survey, in which all accessible surfaces of the radiographic exposure device or source changer are surveyed.G. Perform surveys on storage containers to ensure that the source is shielded and the radiation levels do not exceed the limits specified in Part D. These surveys shall be performed initially with the maximum amount of radioactive material present in the storage location and thereafter at the time of the quarterly inventory and whenever storage conditions change.H. Perform a survey meeting the requirements of E.19.B, on the radiographic exposure device and the source changer after every sealed source exchange.I. Maintain records of the surveys required by E.19 in accordance with Subpart E.10-144 C.M.R. ch. 220, § E-D-19
