a)         The licensee shall make radiation surveys, including but not limited to the surveys required under subsections (b) through (e), of each area where licensed material is used and stored.

 

b)         Before transporting licensed material, the licensee shall make a radiation survey of the position occupied by each person in the vehicle and of the exterior of each vehicle used to transport the licensed material.  The surveys and calculations shall include each source of radiation or combination of sources to be transported in the vehicle.

 

c)         If the sealed source assembly is removed from the logging tool before departure from the temporary jobsite, the licensee shall confirm that the logging tool is free of contamination by energizing the logging tool detector or by using a survey meter.

 

d)         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 shall conduct a radiation survey, including a contamination survey, during and after the operation.

 

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

 

f)         The results of the radiation surveys required under subsections (a) through (e) must be recorded and shall include the date of the survey, the names of the individuals making the survey, the identification of the survey instruments used, and an exact description of the location of the survey.  The licensee shall retain records of these radiation surveys for inspection by the Agency for 5 years after completion of the survey.
