This standard sets forth uniform methods of measurement of radio noise emitted from low voltage electrical and electronic equipment in the frequency range of 10 kHz to 1 GHz. Methods for the measurement of radiated and power-line conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements. These methods apply to the measurement of individual components, units, or systems comprising components and units. Additional… read more methods may be added to this standard to fulfill future requirements as needed. Unless specifically called out, this standard is not intended for certification or approval of avionic equipment. The method for validation of test sites such as open area sites and absorber-lined chambers for frequencies in the range of 30 MHz-1000 MHz is contained in 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

This standard describes minimum performance requirements and test methods for evaluating the performance of alarming personal radiation detectors (PRDs) for homeland security applications. PRDs are pocket-sized battery-powered alarming electronic instruments that are worn on the body and used to detect photon-emitting, and optionally neutron-emitting, radioactive materials. PRDs have user-readable displays related to the intensity of radiation, but they are distinct from, and typically more… read more sensitive than, electronic personal dosimeters, which are designed to measure the dose equivalent to workers occupationally exposed to radiation. The performance criteria contained in this standard are meant to provide the means for verifying the capability of the PRDs to reliably detect changes above background levels of ionizing radiation fields and alert the user to these changes. This standard also specifies the requirements and test methods for environmental, electromagnetic, and mechanical conditions that may affect the ability of the PRDs to function properly. This standard does not apply to spectroscopic PRDs that have the ability to identity radionuclides. The ANSI N42.48 standard [B12] covers spectroscopic PRDs.1 This standard does not apply to instruments that are primarily intended to provide a measurement of dose-equivalent, personal dose-equivalent, or ambient dose-equivalent rate. However, if the manufacturers of PRDs that provide an indication of personal dose-equivalent rate (expressed in units of mrem/h or μSv/h) claim that the PRD may be used for personal protection, then the PRD shall comply with the applicable radiological requirements described in ANSI N42.20 [B17] (i.e., accuracy, energy, and angle response tests). read less

The purpose of this standard is to specify performance criteria and type-test methods used to evaluate portable radiation detection instruments. These instruments are used for detection of photon emitting radioactive materials and photon exposure rates. Instruments are used for the purposes of detection, interdiction and prevention. Instruments may include alarms to indicate an increase in exposure rate. This standard does not apply to instruments that are primarily intended to provide a… read more measurement of dose equivalent rate. In a departure from other DHS-related ANSI N42 instruments standards, some issues of Radiological/Nuclear initial response (R/N initial response) are discussed. A tactical description of R/N initial response is provided in this revised standard in Annex H and is generally linked to related R/N initial response instrumentation situations in ANSI N42.32, ANSI N42.34, ANSI N42.35, ANSI N42.38, ANSI N42.43, ANSI N42.53, and directly linked to ANSI N42.49A. This direct link is from a portable instrument with low exposure rate range to a portable instrument of a much higher exposure rate range. This instrument range change may be necessary in some R/N initial response situations. read less
