Overview Scope The purpose of this standard is to specify performance criteria and test methods used to evaluate portable radia
24、tion detection instruments. These instruments are used for detection of photon-emitting radioactive materials and quantification of photon exposure rates. Instruments are used for the purposes of detection, interdiction, and prevention. This standard does not apply to instruments that are primarily
25、intended to provide a measurement of dose equivalent, or dose equivalent rate. Purpose The purpose of this standard is to specify technical performance requirements and performance testing requirements for those purchasing and using portable radiation detectors for Homeland Security applications.

40、3.3 accepted ambient photon background: The background radiation as measured using a high pressure ionization chamber, an energy compensated Geiger-Mueller (GM) tube, an energy compensated proportional counter, a tissue equivalent plastic scintillator, a scintillator with spectral compensation, or a
41、ny other exposure rate instrument having a nearly constant energy response (30% in the energy range from 60 keV to 1.5 MeV). 3.4 accredited testing laboratory: Testing laboratory that has been accredited by an authoritative body with respect to its qualification to perform verification tests on the
42、type of instruments covered by this standard. 3.5 accuracy: The degree of agreement between the observed value and the conventionally true value of the quantity being measured. 3.6 adjust: To alter the reading of an instrument by means of a built-in variable (hardware or software) control. 3.7 alarm
43、: An audible, visual, or other signal activated when the instrument reading or response exceeds a preset value or falls outside of a preset range. 3.8 calibrate: To adjust and/or determine the response or reading of a device relative to a series of conventionally true values. 3.9 calibration: A set
44、of operations under specified conditions that establishes the relationship between values indicated by a measuring instrument or measuring system, and the conventionally true values of the quantity or variable being measured. 3.10 check source: A not-necessarily calibrated source that is used to con
