This guide is intended to provide a basic understanding of the application, evaluation, and safety considerations of electromagnetic interference (EMI) power-line filters used in both ac and dc applications. It includes a basic description of the construction of an EMI power-line filter and its functions in providing suppression of conducted noise. In addition, it provides explanations of why seemingly identical filters may not give the same performance in a particular application. Finally,… read more proper installation of these filters in equipment is discussed. read less

This standard defines the procedures to be used by manufacturers in testing direct and indirect reading quartz fiber pocket dosimeters relative to the performance specification described in ANSI N13.5-1972. The testing procedures apply to those dosimeters designed to respond to X and gamma radiation with energies extending from 20 keV up to 3 MeV. This specification does not include test requirements for direct reading dosimeter chargers and is only partially applicable to charger readers for indirect reading dosimeters.

This standard establishes methods for performance testing, calibration, and usage of thallium-activated sodium iodide [NaI(Tl)] detector systems for the measurement of gamma ray emission rates of radionuclides; the assay for radioactivity; and the determination of gamma ray energies and intensities. It covers both energy calibration and efficiency calibration. The following three techniques are considered: a) Total spectrum counting (see 4.1) employs a system that counts all pulses above a low-… read more energy threshold (see 6.1, 6.2, and 6.3). b) Single-channel analyzer (SCA) counting (see 4.2) employs a system with a counting "window," which establishes upper and lower energy boundaries (see 6.1, 6.2, and 6.3). c) Multichannel analyzer (MCA) counting (see 4.3) employs a system in which multiple counting windows are utilized. This technique allows measurements for which the continuum under the full energy peak may be subtracted without introducing unacceptable error. In case of overlapping peaks in the spectrum, it is realized that an MCA with access to a spectrum-stripping program is necessary. Such cases are not covered by this standard. read less

This standard applies to wide-bandgap semiconductor radiation detectors, such as cadmium telluride (CdTe), cadmium-zinc-telluride (CdZnTe, referred to herein as CZT), and mercuric iodide (HgI2) used in the detection and measurement of ionizing radiation at room temperature; gamma rays, X-rays, and charged particles are covered. The measurement procedures described herein apply primarily to detector elements having planar, hemispherical, or other geometries in which charge carriers of both… read more polarities contribute to the output signal. When the devices are an integral part of a system, it may not be possible for a user to make tests on the detector alone. In this instance, tests on the detector element must be established by mutual agreement between the manufacturer and the user. read less

The standard describes the requirements and the procedures for testing such dosimeters against these requirements. The requirements apply to direct reading dosimeters designed to measure ionizing electromagnetic radiation (X-rays or gamma-rays) with energies from approximately 20 keV to 3 MeV. Procedures are given for the testing of any accessory electrometers or chargers that are used to operate, or read-out, these dosimeters.

This standard sets forth uniform methods of measurement of the electromagnetic and operational compatibility of unlicensed personal communications services (UPCS) devices. This standard does not cover licensed personal communications services (PCS) devices. The recommended methods are applicable to the radio transmitter and monitoring devices contained in the UPCS device. These methods apply to the measurement of individual UPCS devices. Additional methods may be added to this standard to… read more fulfill future requirements. In addition to the measurements specified herein, UPCS devices may also be required to be tested in accordance with other standards. Examples are listed in Annex A. read less
