31.13 exposure: The measure of ionization produced in air by x or gamma radiation.
NOTE I— The sum of electrical charges of all ions of either sign produced in air when all electrons liberated by photons in a volume clement of air arc completely stopped in air, divided by the mass of the air in the volume clement. Thc special unit of exposure is the Roenigen, abbreviated in this standard as R. Thc exposure rate is the Roentgen per hour (Rb).
NOTE 2 In this standard the System Imernatiormie (SB wiit sievert or Sv follows in parentheses the Roentgen value R. though the t units arc NOT physically equivaleni.
3.1.14 extreme conditions: Environmental conditions beyond those specified in this standard.
3.1.15 false alarm: An alarm NOT caused by a radiation source. See: alarm.
3.1.16 first level training: This introductory level of training is appropriate for those individuals who are expected to detect the presence of radioactive materials, protect themselves, call for more highly trained personnel at levels two and three for control andor mitigation and secure the area.
NOTE These personnel may be the first to employ radiation measuring instruments such as personal detectors or portal monitors used to detect radioactive materials used or transported for illicit purposes, These personnel arc not trained to assess the alarm as a false alarm, an innocent or nuisance alarm, or legitimate alarm.
3.1.17 functional check: A frequendy used qualitative check to determine that an instrument is operational
and capable of performing its intended function.
NOTE Such checks may include, for example. battery check, iero setting, or source response check.
3.I.lX gamma radiation: Ionizing radiation consisting of photons emitted from the nucleus of an atom through nuclear transition or particle annihilation.
3.1.19 illicit radioactive niaterial: Any quantity of Special Nuclear Material and significant quantities of any nuclide in the International Atomic Energy Agency (IAEA) threat list.
3.1.20 indicated value: A scale or decade reading OR the displayed value of the readout. See: reading.
3.1.21 indication: l)isplayed signal from the instrument to the user conveying infrirmation such as scale or decade. status, malfunction or other critical information.
3.1.22 instructor: Qualified personnel who shall conduct classes according to approved lesson plans and organizational procedures.
3.1.23 instrunient: A complete system consisting of one or more assemblies designed to quantify one or more characteristics of’ ionizing radiation or radioactive material.
3.1.24 interdiction: Detecting and stopping the illicit or inadvertent movement of radioactive material, that has been discovered as a result of radiation detection or measurement.
3.1.25 monitoring: Means provided to continuously indicate the state or condition of a system or assembly.
NOTE—For purposes of this standard the real time measurement of radioactivity or radiation level.
3.1.26 neutron: Elementary nuc lear particle with no charge.
3.1.27 NRRPT registration: Registration by the National Registry of Radiation Protection Technologists.
3.1.28 05cr-range response: The response of an instrument when exposed to radiation intensities greater than the upper measurement limit.
3.1.29 performance test: An evaluation of the performance of an instrument in response to a given influence quantity.
3.1.30 personal radiation detector: An alarming personal radiation detector worn on the body to detect photons (and in some cases neutrons) in compliance with the requirements of ANSI N42.32.
NOTE—May be abbreviated as a PRD and also known as a ‘pagcr.
3.1.3 1 point of measurement: Place at which the known values are determined and at which the reference point of the instrument is placed fbi test purposes.
3.1.32 portal monitor: A radiation detector or system of radiation detectors capable of measuring photon and neutron radiation emitted from a package. person, or vehicle, in compliance with the requirements of
ANSI N42.35.
NOTE—Also known as a radiation portal monitor and may be abbreviated as RPM. The narrower definition from ANSI N42.35 is: Radiation detection system that measures radiation intensity, compares it to alarm criteria, and produces an alann if the measured intensity exceeds the criteria.
3.1.33 portable radiation detector: A hand-held radiation detector capable of measuring photon exposure rates in compliance with the requirements of ANSI N42.33.
3.1.34 post-event: For purposes of this standard, relevant radiation measuring activities following the release andjor spread of radioactive materials. andor detonation of a nuclear/radiological weapon of mass destruction.
NOTE—Post-event includes the homeland security missions of “respond arid recover” as defined in the U.S. Department of homeland Security(DIIS) Universal Task List.
3.1.35 practicum: A supervised curriculum emphasizing hands-on use of practical applications of the referenced radiological instruments, i.e.. personal detectors or pagers. portable instruments, radionuclide identifiers with neutron indications and portal monitors, as defined in ANSI N42.32. ANSI N42.33, ANSI N42.34, and ANSI N42.35.
