Oregon Administrative Rules
Chapter 333 - OREGON HEALTH AUTHORITY, PUBLIC HEALTH DIVISION
Division 113 - RADIATION SAFETY REQUIREMENTS FOR WIRELINE SERVICE OPERATIONS AND SUB-SURFACE TRACER STUDIES
Section 333-113-0401 - Radiation Surveys

(1) Radiation surveys must be made and recorded for each area where radioactive materials are used and stored.

(2) Radiation surveys must be made and recorded before transport for the radiation levels in all occupied positions and on the exterior of each vehicle used to transport radioactive material. Such surveys must include each source of radiation or combination of sources to be transported in the vehicle.

(3) If the sealed source assembly is removed from the logging tool before departing the jobsites, the logging tool detector must be energized, or a survey meter used, to assure that the logging tool is free of contamination.

(4) Radiation surveys must be made and recorded at the jobsite or well-head for each tracer operation, except those using hydrogen-3, carbon-14 and sulfur-35. These surveys must include measurements of radiation levels before and after the operation.

(5) If the licensee has reason to believe that, as a result of any operation involving a sealed source, the encapsulation of the sealed source could be damaged by the operation, the licensee must conduct a radiation survey, including a contamination survey, during and after the operation.

(6) The licensee must make a radiation survey at the temporary jobsite before and after each subsurface tracer study to confirm the absence of contamination.

(7) Records required pursuant to sections (1) through (6) of this rule must include the dates, the identification of individual(s) making the survey, the identification of survey instruments(s) used and an exact description of the location of the survey. Records of these surveys must be maintained in accordance with 333-100-0057.
