27、tional Standard for Performance Specifications for Health Physics Instrumentation-Portable Instrumentation for Use in Normal Environmental Conditions1. ScopeThis standard establishes the minimum performance criteria for health physics instrumentation for use inionizing radiation fields. Testing meth

28、ods are included to establish the acceptability of each type ofinstrumentation. This standard does not specify which instruments or systems are required, nor does itconsider the number of specific applications of such instruments.1.1 IntroductionThe object of this standard is to provide basic perfor

29、mance requirements and verification test methods forportable instruments used in normal environmental conditions for radiation protection of personnel.As used in this standard, health physics instrumentation provides direct readout of, or readout related to,dose and dose-equivalent rate, or activity

30、-per-unit area (i.e., effective probe area). Included are portable rateand integrating devices for beta, photon, and neutron radiation and monitors for surface contamination(alpha, beta, and photon). Instruments used to measure the presence of low-energy beta emitters (i.e., lessthan 200 keV maximum

31、 energy) are not addressed in this standard. Personnel dosimeters; instrumentsdesigned to be used as individual or personal monitors, or warning devices; environmental monitoringinstruments; and air monitors are outside the scope of this standard. Special purpose instrumentation, such asemergency po

32、st-accident radiological monitors, may also fall under the scope of one or more related ANSIstandards. This standard is intended to supplement rather than replace these.In general, health physics instrumentation is considered to cover the dose and dose-equivalent rate rangesfor survey meters of 0.1

33、mrad/h to 1000 rad/h (1 Gy/h to 10 Gy/h) and 0.1 mrem/h to 1000 rem/h (1 Sv/hto 10 Sv/h). It covers activity-per-unit-area ranges for surface contamination monitors of 50 disintegrationsper minute (dpm)/cm2to 104dpm/cm2(0.83 Bq/cm2to 167 Bq/ cm2) for beta/photon radiation and 1dpm/cm2to 104dpm/cm2(0

34、.02 Bq/cm2to 167 Bq/cm2) for alpha radiation.ANSIStd N42.17A-2003 AMERICAN NATIONAL STANDARD FOR PERFORMANCE SPECIFICATIONS 2 Copyright 2003 IEEE. All rights reserved.For specific characteristics, test requirements will vary with the use of the instrument. For example, therequirements for a laborato

35、ry instrument are not as demanding as requirements for an instrument to be usedin an uncontrolled environment. Table B.1 lists the characteristics in the standard and the associated clausewhere the requirements and test can be found.This standard specifies general characteristics; general test proce

36、dures; radiation characteristics; andelectrical, mechanical, safety, and environmental characteristics. Throughout this standard, three verbs havebeen used to indicate the degree of rigor intended for each specific criterion. The word shall is used todenote a requirement, the word should to denote a

37、 recommendation, and the word may to denote apermissible practice.If the operational conditions for an instrument are less severe than the requirements of this standard, then theinstrument manufacturer and the purchaser may agree upon the instrument performance specifications;however, the instrument

38、 should be tested using the testing protocol of this standard.2.
