This standard establishes calibration methods for portable radiation protection instruments used for detection and measurement of levels of ionizing radiation fields or levels of radioactive surface contamination. For purposes of this standard, portable radiation protection instruments are those which are carried by hand to a specific facility or location for use. Although this standard is specific to portable radiation protection instrumentation, the basic calibration principles may be… read more applicable to radiation detection instrumentation in general. Included within the scope of this standard are conditions, equipment, and techniques for calibration as well as the degree of precision and accuracy required. Alpha, beta, photon, and neutron radiations are considered. Passive integrating dosimetric devices such as film, Thermoluminescent, and chemical dosimeters are outside the scope of this standard, but the basic principles and intent may apply. In cases where integrating capability is included along with rate measurement or detection, this standard shall apply. Throughout these criteria, four verbs have been used to indicate the degree of rigor intended by the specific criterion. "Shall" and "will" indicate a minimum criterion that must be met, while "should" and "would" indicate a criterion that is recommended as good practice and is to be applied when practical. read less

This standard provides requirements, methods, and guidelines to be applied to the evaluation of uncertainty in testing the accuracy of Instrument Transformers (IT) intended for applications where the rated primary voltage is higher than 1 kV High-Voltage (HV) or lower than 1 kV Low-Voltage (LV). It applies to applications with an analog or a digital secondary signal for measuring, protection, and control purposes, with rated frequencies from 15 Hz to 400 Hz. This document covers the uncertainty… read more evaluation in testing the accuracy of IT (including on-site testing of accuracy) independently of the technology used (either inductive or non-inductive). The document reports on how to take into account the sources of uncertainty in the setups for accuracy tests and how to combine their effects in order to evaluate the uncertainty in the test results. read less

This standard establishes methods for the calibration and use of gas proportional counters with and without active guard detectors. This standard also establishes methods for measuring the alpha and beta counting plateau, crosstalk factors, background, alpha and beta efficiency from prepared standards, correction factors for samples whose self-attenuation or mass differs from that of the standard, and calculation of the sample activities together with their random and total uncertainties.… read more Correction for pulse pileup due to high count rate is also discussed. Although many principles articulated in this standard apply to the counting of radionuclides emitting a maximum beta energy below 100 keV as well, the counting of these low-energy beta emitters requires a higher degree of attention to detail in sample preparation, instrument calibration, and measurement correction factors than addressed in this standard. Therefore, this standard is intended for measuring radionuclides with maximum beta energies above 100 keV. read less

This standard establishes methods for performance testing, calibration, and usage of sodium iodide detector systems for the measurement of gamma-ray emission rates of radionuclides; the assay for radioactivity; and the determination of gamma-ray energies. It covers both energy calibration and efficiency calibration. The following three techniques are considered: (1) Total spectrum counting (see 5.1) employs a system that counts all events above a low-energy threshold (see 7.1, 7.2, and 7.3). (2)… read more Single-channel analyzer counting (see 5.2) employs a system with a counting window which establishes upper and lower energy boundaries (see 7.1, 7.2, and 7.3). (3) Multichannel analyzer counting (see 5.3) employs a system in which multiple counting windows are utilized. This technique applies to measurements that do not involve overlapping peaks and those for which the continuum under the full-energy peak can be subtracted without introducing unacceptable error [4]. read less

This standard defines a joint calibration framework for multiple roadside sensors (such as camera, Light Detection and Ranging (LiDAR), millimeter wave radar, and fused sensors). The standard defines the types of sensors involved (including their characteristics and measurement data features), the reference coordinate system, the calibration process and the tools for calibrating the sensors. Additionally, the standard defines a data analysis method to assess the accuracy and reliability of the calibration results.
