What are the physicists' responsibilities with respect to the requirement for calibration of their air kerma measuring instruments?

Policy Guidance Help System logo

The physicist must use an instrument that has been calibrated (by the National Institute of Standards and Technology (NIST) or by a laboratory that participates in and has met NIST’s proficiency test requirements) within the last two years or since its last repair to an accuracy of +/- 6 percent (95 percent confidence level) in the mammography energy range. The physicist should plan ahead for calibrations so as to provide adequate time for his or her chosen calibration laboratory to complete the work in time.
