HPS ANSI/HPS N13.44 PDF

This standard provides the specifications for the design and fabrication of physical thyroid phantoms to be used in the calibration of in vivo measurement systems. This standard includes criteria for acceptable materials, physical specifications, quality assurance, and quality control. This standard does not specify fabrication techniques or component testing techniques.

This standard provides guidance for modeling acceptable nonphysical, computational thyroid phantoms. Quality assurance requirements are provided for the use of the model in Monte Carlo computations.

This standard recommends good practices as to the use of thyroid phantoms for radiological dosimetry purposes, including uncertainty assessment from improper calibrations.

Purpose

This standard establishes the criteria for acceptable design, fabrication, or modeling of a phantom suitable for calibrating monitoring systems for in vivo measurement of photon-emitting radionuclides deposited in the thyroid.
