Thyroid Radioiodine Intercomparison Program(TRIP)1
Direct measurement of nuclear medicine staff2
Future research planning3
The Thyroid Radioiodine Intercomparison Program (TRIP) provides
participating facilities with an independent means of evaluating in vivo
thyroid radioiodine measurements, using the International Atomic Energy
Agency (IAEA)/American National Standards Institute (ANSI) thyroid
calibration neck phantom (see International Commission on Radiation Units
& Measurements [ICRU] Report #48) and NIST- traceable isotopes for 125I
and 131I.
TRIP is coordinated by the Radiation Protection Functional Area and
Assurance Management Office of the Environment, Safety and Health
Directorate at Lawrence Livermore National Laboratory (LLNL) in
Livermore, CA.
LLNL established TRIP in response to requirements by ANSI N13.30,
ISO/IEC 17025 (Section 5.6.2.1.1), Department of Energy Laboratory
Accreditation Program (DOELAP), and other regulatory agencies for
participation in a suitable program of interlaboratory comparison. TRIP
intercomparison results can be used to assist participating facilities in
demonstrating compliance with federal and state regulations.
TRIP was unanimously approved by the Conference Radiation Control
Program Directors, Inc. (CRCPD) as an acceptable accreditation program.
