This standard applies to dosimetry systems used to determinepersonal dose equivalent for occupational conditions and absorbeddose for accident conditions. Tests are conducted under controlledconditions and include irradiation with photons, beta particles,neutrons, and selected mixtures of these radiations. The range ofdelivered absorbed doses or personal dose equivalents and tolerancelevels are based on considerations of radiation protectionexpressed in current publications of the National Council onRadiation Protection and Measurements (NCRP 1993), theInternational Commission on Radiation Units and Measurements (ICRU1992), and the International Commission on Radiological Protection(ICRP 1991, 1997). Organizations should be tested in thosecategories that best represent the dosimetry services they provideor use. The tests outlined in this standard may be used to test thesuppliers of dosimetry services (processors).
The standard integrates angular testing using photon fieldsincident at various angles to the plane of the dosimeter. Suchtests provide the test participant with:
a method to continuously evaluate long-term changes in dosimeterconstruction, and
information for improving absorbed dose or personal doseequivalent estimation under field conditions.
Several dosimetry uses and radiological conditions are outsidethe scope of this standard because of dosimeter design, limitationsof dosimetry systems, and practical considerations of testingequipment and sources.
These include:
thermal neutrons,
high-energy neutrons (E ≥ 3 MeV), and extremity dosimeters(covered in ANSI/HPS N13.32-2008).
The scope of this standard is sufficiently comprehensive thatsatisfactory performance implies that a dosimetry processor or useris competent to assess personal dose under a broad range of fieldconditions using the tested dosimetry system for those categoriesfor which they were tested.
