This recommended practice defines a common viewpoint of the evaluation of uncertainty in calibration and its application in testing procedures for Instrument Transformers (ITs). Definition of how to take into account the sources of uncertainty of the measurement system and how to combine their effects in order to evaluate the uncertainty on the measurement results. The recommended practice also presents the common requirements to be used during tests for assessing the accuracy of ITs.
This standard establishes specific calibration and calibration-related requirements 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 battery-powered instruments that are carried to a specific facility or location for use. Count rate meters and scalers, when used with an appropriate detection… read more probe for quantifying activity, can be considered portable radiation protection instruments and should be treated as a single unit for the purposes of this standard. read less
This standard covers the technique for the quantification of the activity of identified radionuclides using any of a variety of ionization chambers currently available for this purpose. Application of the standard is limited to instruments that incorporate well-type ionization chambers as detectors.
