29、duction or networking permitted without license from IHS-,-,-American National Standard Performance Criteria for Active Personnel Radiation Monitors1. Overview1.1 PurposeThe purpose of this standard is to specify performance and design criteria for personal electronic monitorsused for the determinat
30、ion of personal dose equivalent, or dose equivalent rate from external sources, ofradiation. It is necessary to standardize the performance and design of devices used for this importantpurpose. Recent developments in this area of instrumentation have necessitated the revision of ANSIN42.20-1995 for
31、these devices. This standard should be used in conjunction with ANSI N42.17a-2003.11.2 ScopeThis standard applies to the following types of active electronic devices that are worn on the trunk of thebody for the purpose of measuring the personal dose equivalent, or dose equivalent rate from external
32、sources, of radiation. The types of dosimeters, include those designed for measuring, are the following:Type 1X, gamma, and high energy beta radiationsType 2Neutron radiationType 3X, gamma, high energy beta, and neutron radiations (i.e., total dose)The standard specifies the design and performance c
33、riteria for the personal electronic dose monitors and, ifsupplied, the associated readout system. It applies to devices used for the measurement of personal doseequivalent (rate) from photon radiations (X-rays and gamma rays) of energies 50 keV to 1.5 MeV, betaradiation of maximum energies greater t
34、han 500 keV, and neutron radiation from thermal energies toapproximately 15 MeV.This standard does not include instruments referred to as chirpers, which are described in ANSI N13.27-1981. This standard does not specify methods for the proficiency testing and accreditation of dosimetrysystems. The s
35、tandard addresses only the radiation detection portions of instruments with telemetriccapability. It also does not address passive devices such as thermoluminescent dosimeters, photographicfilm dosimeters, or quartz fiber electroscope dosimeters. This standard specifies the following items foractive
36、 personal electronic dosimeters: required general characteristics; general testing procedures; radiation1Information on references can be found in Clause 2.Copyright 2004 IEEE.

37、and Electronics Engineers, Inc. Provided by IHS under license with IEEENot for ResaleNo reproduction or networking permitted without license from IHScharacteristics; and electrical, mechanical, safety, and environmental characteristics. The standard specifiesthe criteria for validating the accuracy
38、of stored dosimetry information. This standard should be used for theevaluation of active personal electronic dosimeters as part of a type testing program or a qualification of thedevices for purchase and subsequent use in a radiation protection program. The proficiency testing oraccreditation of th
39、ese devices is covered in related standards developed by Accredited Standards Committee(ASC) N13.1.3 Relationship to international standardsThis standard is consistent with standards being developed by IEC TC45/SC45B. In addition to ANSI defi-nitions, it utilizes definitions of IEC 60050-394:1995 B1
40、2and ISO standards on reference radiations, but itdoes not use the ICRU operational quantities given in IEC 60050-394:1995, because they have not yet beenadopted in the United States.2.
