08:20 The Health Physics Society Standards Committee (HPSSC) A Triventi*, Health Physics Society Standards Committee (HPSSC)
Abstract: The Health Physics Society Standards Committee (HPSSC) is the Health Physics Society (HPS) permanent committee on health physics/radiation protection standards and provides direct support to the HPS in all issues involving health physics/radiation protection-related standards.
The HPS is the Secretariat for two American National Standards Institute (ANSI) Accredited Standards Committees (ASCs) in the areas of health physics/radiation protection: N13, “Radiation Protection”, and, N43, “Equipment for Non-Medical Radiation Applications” (excluding nuclear reactors).
The HPSSC oversees the activities of ANSI ASC N13 and ANSI ASC N43 with the intent of ensuring integration among the respective standards. The purpose of the HPSSC is to direct the writing and the publication of the ANSI/HPS consensus-balloted standards in response to requests from various organizations and individuals or upon the initiative of the HPSSC itself. The HPSSC is also concerned with HPS organizational representation to other national and international standards organizations such as ISO/TC85/SC2.

08:30 ANSI/HPS N13 Radiation Protection Standards JM Barnett*, PNNL
; CA Potter, Sandia National Laboratories
Abstract: Accredited Standards Committee (ASC) N13, Radiation Protection, is responsible for developing United States national consensus standards dealing with or pertaining to radiation protection. Radiation protection includes the protection of individuals or groups from occupational or environmental exposure to radiation or radioactive materials. N13 operates semi-autonomously as part of the HPS infrastructure, and outside of the normal HPS committee structure where consensus standards are developed independently. ASC N13 membership is comprised of technical experts and organizational representatives from government or regulatory agencies, professional societies, and labor unions or trade associations. Administration of N13 activities is performed by an Administrative Committee which includes the Chair, Vice Chair, Standards Coordinator/Secretary, and the five Technical Section Managers. The technical sections include Environmental, External Dosimetry, Internal Dosimetry, Medical and Operational Health Physics, and Instrumentation. The structure and process used by N13 is explained, a summary of recent standards activities and actions is provided, and the process for becoming involved is discussed. This paper describes objective technical results and analysis. Any subjective views or opinions that might be expressed in the paper do not necessarily represent the views of the U.S. Department of Energy or the United States Government.

08:50 Overview of Accredited Standards Committee N43 CR Jones*, Accredited Standards Committee N43
Abstract: The Accredited Standards Committee N43 on Equipment for Non-Medical Radiation Application is established under the purview of the Health Physics Society Standards Committee (HPSSC) and accredited by the American National Standards Institute (ANSI). The N43 committee develops and maintain national consensus standards pertaining to radiation safety for products, devices and equipment for industrial, security, and educational uses involving ionizing radiation sources, excluding nuclear reactors. The committee membership consists of representatives of government/regulatory agencies, the military departments, professional societies, and industry, as well as individuals with an interest in the committee's work. The membership provides broad representation of various interests in the development of national standards. There are currently 14 national consensus standards approved or under development within the purview of the N43 committee. The subcommittees for each of these standards also seek for broad representation from organizations and individuals with interest in the radiation safety aspects of their respective standards.

09:10 Participation In International Radiation Protection Standardization JF Herrold*, University of Wyoming
Abstract: The American National Standards Institute (ANSI) accredits Technical Advisory Groups (TAGs) that coordinate U.S. positions and participate in the activities of the International Organization for Standardization (ISO), including the development, reaffirmation and revision of ISO standards. ASTM International functions as Administrator for 55 U.S. TAGs, including ISO Technical Committee 85 (TC 85) with the scope of “nuclear energy, nuclear technologies, and radiological protection.” TC 85 Subcommittee 2 (SC 2) has published 119 standards on radiological protection and 27 in development. The Health Physics Society Standards Committee (HPSSC) is the organizational sponsor for participation in the TC 85/SC 2 TAG that submits ballots (through ANSI) and promotes participation in ISO working groups. Currently 40 members of the HPS are involved in eleven SC 2 working groups. In 2021, ISO/TC 85/SC 2 distributed 58 ballots for the review or revision of radiation protection standards. Participating Member countries must vote on each draft standard to approve (with or without comments), to disapprove, or to abstain. Every country gets one vote, but could lose their Participating Member status if they fail to respond to all ballots. In order for ISO standards to remain relevant, every five years they must undergo a systematic review and another ballot on whether it should be updated or withdrawn. In 2020, the U.S. TAG for ISO/TC 85 revised its internal operating procedures, in line with ANSI guidelines. At the same time, ASTM determined they need to begin managing the voting process for ISO ballot items and other functions. New procedures for electronic balloting and expert volunteer participation will probably take place in 2024. The author will discuss the many benefits of participating in ISO standard working groups and reviews, and how radiation safety professionals can get involved.

10:00 N13 Standard on Incineration of Low-Level Radioactive Waste RP Reed*, Consultant
Abstract: American National Standard/Health Physics Society (ANSI/HPS N13.45-2012) “Incineration of Low-Level Radioactive Waste “ is being updated to reflect current technical and regulatory requirements and guidance. Work on the revision began in 2022 and continues. A working group has been formed to review the standard, including representatives from industry, government, hospitals, and universities. In addition to the working group, a representative from a major waste management firm has been invited to review and provide comments on the revision. The standard addresses the following topics on low-level radioactive waste incineration: objectives, a glossary of terms, acronyms, identification of waste sources, selection of incinerator equipment, incinerator siting considerations, administrative and operational controls, monitoring program, disposal of residues, documentation, decontamination and decommissioning, licensing and permitting requirements, a discussion of major agencies that regulate air quality, modeling methods and a bibliography. The standard also has a flowchart for process flow for the incineration of combustible liquid waste, liquid scintillation cocktail, biological waste, and combustible solid waste.

10:15 Radiation Safety Standards for Security Inspection of Humans (ANSI/HPS N43.17) JL Glover*, NIST
Abstract: ANSI/HPS N43.17 is a radiation safety standard for security screening systems that deliberately expose people to ionizing radiation, for example, to search for weapons, drugs, or other illicit items. It provides guidelines, measurement methods, and dose limits and is the most-widely used standard of its type in the US and internationally. In the past, it was the main metrological tool used to regulate the dose delivered to air travelers by the x-ray backscatter personnel scanners used in US airports. Today, it is widely applied to transmission x-ray personnel-screening systems, such as those used in US prisons, and for occupied-vehicle scanners. Over the past two decades, there have been many changes to the ways people are screened with ionizing radiation, but one constant has been the importance of ANSI/HPS N43.17 in ensuring people are screened safely.

10:30 Overview of ANSI/HPS N43.16 CR Jones*, Accredited Standards Committee N43
Abstract: American National Standards Institute/Health Physics Society (ANSI/HPS) N43.16 is a new standard published in January 2021. It provides guidance and performance criteria for radiation safety aspects of non-instrusive inspection (NII) for security screening of vehicles and cargo containers. The standard adresses devices that use x rays or gamma rays up to 10 MeV for security screening scenarios where human occupant are not intentially exposed to the primary radiation beam. The standard establishes recommended dose limits for system operators, bystanders, and inadvertently scanned individuals. It also establishes performance criteria related to system design, installation, and operation. Several annexes in the standard provide procedures for making the measurements required by the standard, as well as general information about security screening systems and their uses.
