Resolution of Generic Safety Issues: NRC:NMSS-0005. Potential for Erroneous Calibration, Dose Rate, or Radiation Exposure Measurements with Victoreen Electrometers ( NUREG-0933, Main Report with Supplements 1–35 )

DESCRIPTION

This issue was identified1705 by NMSS when Victoreen, Inc., notified the NRC that some of its Model 530 and 530SI Electrometer/Dosimeter instruments were susceptible to developing cracks in their internal resistor networks. These cracked networks could cause erroneous radiation exposure readings either above or below the actual values.

CONCLUSION

The issue was resolved1701 when the responses to Bulletin 97-011706 submitted by the affected licensees were deemed to be adequate by the staff.1707
