Subject: Announcement - Workshop on Specifications for Standard In Vivo
Radiobioassay Phantoms
Comments: cc: Bert Coursey , lisa.karam@nist.gov
To: RADCH-L@in2p3.fr
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.
Specifications for Standard In Vivo Radiobioassay Phantoms
October 29 30, 2001
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/
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.
