This standard specifies the performance requirements and tests for mobile radiation monitors (MRMs) that detect and/or identify radionuclides, and when provided, indicate the presence of neutron radiation. MRMs are typically in operation on a platform, such as a vehicle or trailer, that is in motion but that can also be used while stationary. This standard does not address radiation monitors mounted on boats or aerial platforms.

This standard provides a means to assess the UARaMS effectiveness to search for, localize, and perform a… read more radionuclide identification of a radiological source, and to characterize an area in terms of contamination levels. This standard does not address flight performance, operational functions, or control of UAVs. This standard also does not address UARaMS used to measure dispersed airborne radioactive contamination (e.g., plumes). The UAVs of interest include those from Group 1 and Group 2 designations found in U.S. Department of Defense (DoD) “Unmanned Aircraft System Airspace Integration Plan, Version 2.0, March 2011” [B8] and “U.S. Army Roadmap for Unmanned Aircraft Systems, 2010-2035” [B4]. read less

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

These test procedures cover amplifier and preamplifier systems with linear pulse-shaping networks for use with semiconductor, scintillation, and proportional detectors in the spectroscopy of ionizing radiation. The object is to provide a common language and methodology for users and manufacturers of pulse-amplifier systems. This standard supersedes IEEE Std 301-1976, IEEE Standard Test Procedures for Amplifiers and Preamplifiers for Semiconductor Radiation Detectors for Ionizing Radiation. Test procedures for associated detectors are described in ANSI/IEEE Std 300-1988 and ANSI/IEEE Std 325-1986. IEEE Std 194-1977 is a companion document for pulse-shape terminology. Not all of the tests described herein are mandatory, but those that are performed to determine preamplifier and amplifier specifications shall conform to this standard. The emphasis on the methods of measurement is to enhance sensitivity and improve accuracy by working around the limitations of the test instruments, particularly oscilloscopes that have only a visual display for readout. A null technique is used where possible, thereby reducing basic errors to the inaccuracy of a pair of precision resistors. When use of a bridge is inappropriate, such as in measurements of pulse height with an oscilloscope, the pulse is made to occupy a fixed amplitude and vertical position on the face of the cathode-ray tube (CRT). Some measurements require test instruments or fixtures not commercially available at this writing; circuit diagrams for their construction are given in the Appendix. It is not acceptable to make use of a standard nuclear instrument module to test the performance of an amplifier unless the errors introduced by that module can be corrected for or shown to be less than the error caused by the amplifier. Examples are the use of a crossover-pickoff module to measure crossover walk in a bipolar amplifier, and an MCA to measure nonlinearity and noise.

This guide identifies factors that should be considered in accelerated aging programs and is intended to be supportive of the aging requirements called for in IEEE Std 323-1983 and its subsidiary standards. This guide presents methodologies for conducting accelerated aging tests in which factors of synergistic interactions, radiation dose-rate effects, oxygen diffusion rates, etc., need to be considered. This guide does not define specific requirements for appropriate radiation exposure sources,… read more selection of specific levels of thermal or radiation exposure, or specific properties to be monitored; nor does it make recommendations for sequencing or combining aging stresses for particular materials or circumstances.
