28、ionOccupational Airborne Radioactivity Monitoring Instrumentation1. ScopeThis standard species performance criteria and testing procedures for instruments and instrument systems designedto continuously sample and quantify concentrations of radioactivity in ambient air in the workplace. This standard
29、does not specify which instruments or systems are required, nor does it address the specic locations or applicationsof such instruments.1.1 IntroductionThe objective of this standard is to provide basic performance criteria for instruments and instrument systems used tocontinuously sample and measur
30、e airborne radioactivity concentrations, i.e., continuous air monitors (CAMs). Thestandard includes performance testing criteria for use in generic (type) tests of new instrument models. This standarddoes not apply to routine or acceptance tests. However, selected tests as agreed between the manufac
31、turer and thepurchaser would be applicable for performing routine or acceptance tests.Included in this standard are both gaseous and particulate gross radioactivity monitors, as well as monitors for specicradionuclides or groups of radionuclides used for radiation protection purposes. Instruments de
32、signed to divide theairborne radioactivity into two or more specic components or fractions and monitor each independently are included.An example of the latter is an instrument that independently monitors airborne particulate radioactivity, radioiodines,and beta-emitting isotopes of the noble gases.
33、 Such instruments are called activity fractioning monitors for thepurposes of this standard.Excluded from this standard are monitors used for other purposes, including efuent and process monitors andemergency postaccident monitors, and the class of special-purpose radiation protection instruments de
34、signed tomeasure working-level rather than activity concentration. Tritium and radon monitors are also excluded from thisstandard. Area monitors that are used to characterize ambient radiation levels are not included in this standard;however, area monitors that are used as part of the background cir
35、cuitry for an air monitor shall be tested for thatCopyright The Institute of Electrical and Electronics Engineers, Inc.

36、PERFORMANCE SPECIFICATIONS FOR HEALTH PHYSICS INSTRUMENTATIONpurpose. Instruments excluded from this standard may fall under the scope of one or more related ANSI standards,including ANSI N42.18-1980 (R1985) 6,1N323-1978 (R1983) 8, and N317-1980 (R1985) 7; this standard isintended to supplement rath
37、er than replace these.This standard species criteria and test procedures for the following areas: general, electronic, radiation, interferingresponse, environmental, and air circuit criteria. Throughout this standard, three verbs have been used to indicate thedegree of rigor intended for each specic
38、 criterion. The word shallis used to denote a requirement, the word shouldtodenote a recommendation, and the word mayto denote a permissible practice.Requirements and testing criteria to be used for the evaluation of portable radiation protection instruments undernormal environmental conditions are
39、covered in ANSI N42.17A-1989 4.
