[Intl_DxMedPhys] X-ray Meter Calibration Overseas

[Michael Urgo]

Happy Friday.  I was thinking about this in reference to overseas calibration.  I checked the MQSA (CFR 21 part 900) regs again, and they are very specific about a NIST traceable calibration lab.  See attached screenshots for national standard calibration and definition.  Does anyone know if any overseas labs participates with NIST?  Of course the calibration certificate lists their national standard.  Thanks for any info you can provide.   Donna Davis-Urgo
