NIST, Gaithersburg, MD
A Workshop of the Public & Environmental Radiation Protection
&
Occupational Radiation Protection Subcommittees of the
Council on Ionizing Radiation Measurements and Standards (CIRMS)
http//physics.nist.gov/Divisions/Div846/CIRMS/
Background: Non-invasive in vivo radiobioassay (whole-body and
organ counting) of personnel working with radionuclides or materials with
potential radioactive contamination is a primary method dosimetrists
employ for routine occupational monitoring and accident assessment. The
variability among “homemade” and defacto reference phantoms can
account for up to 80 percent differences among measurement laboratory
results. Measurement comparability and consistency can be ensured through
calibrations based on national standard realistic human-surrogates
(calibration phantoms). A solution to the problem of measurement
variation is the continued development of technological and measurement
quality assurance bases for quantitative site-specific in vivo
radiobioassay.
Considerable progress has been made in the area of in vivo metrology.
Three ANSI standards on phantoms are nearing completion; a computational
method for the validation of counter calibrations was completed and
progress is continuing on improved phantom materials and methods of
phantom comparisons. The use of the ANSI N13.30 Standard Performance
Testing for Bioassay Laboratories has been adopted by USDOE, and
incorporated into the DOE Laboratory Accreditation Program.
Scope: In conjunction with the annual CIRMS conference, the purpose of
this workshop is to review the status of work in the field and to
identify needed areas of development. The workshop is expected to
aid in the prioritization of developmental efforts, identify promising
new avenues of research and identify needs that are not receiving
appropriate attention. Topics will include physical phantoms,
computational techniques and Measurement Quality Assurance.
