One contributing causal f actor was Nentified in that HP procedure'HP-715,," Surveys in Support of Exclusive Use Radioactive Shipments'and Receipt af.Non Exempt-
' "J Radicactive Packeges," did not requ ae any comparison between lurvey.results'at:the front of the shipping container and survey results in the cab' area. The HP-technician, therefore, did not recognize the disparity. An additional l causal factor-identified was that no.. procedural requirement for, independent. verification of survey results existed. Independent verification may.have offset the potential for human; '
l error. TheLGSdetector(JohnsonExtender 33-0705) was tested-satisfactorily _.
following this event es were the detectors used at Quadrex.-therefore: instrument.
s, malfunction'was eliminated;as_.a causal factor.
Corrective Actions Taken-and Results! Achieved a.
On November 12, 1990, Quadrex's Radiation Safety Officer notified LGS, the State 01%
Tennessee, and the carrier, Scientific Ecology Group (SEG) of tha dose rates 1=,ideL t

fa Corrective Actions Taken to Prevent Recurrence The HP technician involved was counseled on' the importance of attedion to detail-t when performing surveys. and was appropriately disciplined on' December 11.':1990.

This procedural non-compliance has-been reviewed, along with other procedural l
non-compliances noted in the inspection report,_as'part of ourJongoing
~
self-assessment process. We will continue to review these types of. issues and-implement corrective actions as'necessary to_further minimize personnel errors.
including those involving procedural:non-compliance.
Date-When full Compliance was Achieved-Full compliance with-associated Regulatory requirements was achieved on November 12,-
1990, at 1734= hours, upon_ completion of allfappropriate notifications. Compliance-has been achieved-upon revision ~of procedure HP-715 and notification of these_ changes-to affected'HP personnel.- This event-is considered to be an isolated occurrence. The counseling / discipline of the involved HP technician, the enhancement of HP-715, and-the performance of an independent verification'of survey.results'are considered
-sufficient corrective measures, e
