Robert,

Especially when the facility uses the TLD results to set the 
electronic dosimeter calibration factors! I have seen this all too 
often when performing NVLAP On-Site Assessments. If they don't agree 
within 2-5%, I'd be very disappointed, when using this technique.

Since each dosimeter responds characteristically in a different 
manner, each should be calibrated independently, using a NIST 
traceable source. In so doing the data can be considered valid, 
highly desirable in any litigation case, or, employee grievance 
filing.
