Surveys
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.
