The National Institute of Standards and Technology (NIST) developed different types of radioactive sources to test radiation detection systems addressed in several of these standard documents [1, 2]. The sources were designed with different objectives in mind. Some of these sources are currently commercially available with the activity values (in units of Bq) required in the standards traceable to the national standard held at NIST [1].
19.3 Document Standards Development Organizations
Document standards can be developed by different groups and organizations. Different development groups may have different focuses and needs depending on the users they represent. Some groups concentrate more on the performance requirements of a particular type of instrument, while others provide guidance for testing, use or calibration of instruments. Standards can also be developed to define specific design requirements for instruments. These groups and organizations include professional societies, trade associations, testing and certification organizations as well as national or international standards development organizations (e.g., IEC, ANSI, IEEE). The following list provides examples of such standards organizations that developed document standards for radiation detection instruments (not all inclusive):
ANSI: American National Standard Institute
ASTM: American Standards for Testing and Materials
DOD: Department of Defense
HPS: Health Physics Society
IAEA: International Atomic Energy Agency
IEC: International Electrotechnical Commission
IEEE: Institute for Electrical and Electromechanical Engineers
ISO: International Standards Organization
The standards organizations such as ANSI or IEC have different committees under which standards are developed. The standards listed in Table 19.1 were developed under the ANSI Standards N42 Committee on Radiation Instrumentation [3] and the IEC Technical Committee 45 Subcommittee B Working Group B15 (TC45B WGB15) [4].
19.4 Issues Considered During the Standards Development
The main principles behind the development of document standards are:
Transparency – need to ensure that they are accessible to all interested parties
Openness – have a broad participation from different sectors that are interested in a specific product/instrument
Impartiality – ensure that the standard does not favor a particular product or manufacturerRelated posts:
