TPM-F.1   14:30  Radiological Monitoring of Emergency Workers and Populations Following Nuclear/Radiological Incidents: Developing an International Standard for Effective Emergency Response SA Dewji*, Georgia Institute of Technology ; J Herrold, University of Wyoming; US NTAG Chair ISO TC 85

Abstract: Nuclear and radiological accidents and events have caused major health and environmental hazards worldwide, affecting large populations. To mitigate the consequences, planners must consider the effects of these incidents from the post-event phase through long-term recovery. The rapid and effective screening, monitoring, and assessment of radiation exposures are critical components during such events. The International Organization for Standardization (ISO) Technical Committee 85, Subcommittee 2 on Radiological Protection has established Working Group (WG) 25 in 2015 to draft ISO 24434-1, which aims to provide guidance for radiological monitoring for emergency workers and population following nuclear/radiological incidents. WG 25, which comprises 60 experts from 15 participating countries, was responsible for drafting the standard. The core members of the convened in Worchester, MA in 2017, in Japan in 2019, and via several virtual meetings to draft the standard. The ISO 24434-1 standard provides general requirements for radiological monitoring, including information collection on the incident, organizing and operating a center for population screening, decontamination, and registration, as well as internal and external exposure assessments. The standard further provides guidance to responsible authorities for preparing and responding to nuclear/radiological emergencies, while emphasizing the importance of planning, training, and communication to ensure effective and timely responses. The standard is completing the balloting process, where comments were invited through participating member administrators. The efforts of WG 25 demonstrate a global commitment to developing effective, standardized approaches to radiological monitoring, which will support public health and emergency management and improve the effectiveness and coordination of responses to such incidents.

TPM-F.2   14:45  Revised International Standardization For The Detection Of Inadvertent Movement And Illicit Trafficking In Radioactive Materials MW LaFontaine, Physics Solutions, US ANSI Expert Delegate, ISO TC 85/SC 2 ; JF Herrold*, University of Wyoming, US TAG Chair, ISO TC 85/SC 2

Abstract: Smuggling and unintended transport of radioactive materials continues to be a global concern. Although a small quantity of intercepted material is potentially nuclear weapons-grade, the majority are stolen/missing radioactive sources or contaminated objects. In 2020, International Organization for Standardization Technical Committee 85, Subcommittee 2 (ISO/TC85/SC2) reactivated working group (WG) 20 to update ISO 22188:2004 (Monitoring for inadvertent movement and illicit trafficking of radioactive material). In January 2021 a focus group of experts reached the following consensus: 1) the body and content of the standard should focus on monitoring practices – technical and performance requirements for instrumentation are now contained in IEC standards; 2) the revision should focus on “best practices” and guidance regarding: training of personnel involved in detection and monitoring; selection of instrumentation; and operational level procedures. To fast-track the revision process, the clauses of ISO 22188 were divided among the focus group experts. The revision comprises: a) an updated list of normative and bibliographic references; b) training requirements for border agents, inspectors and first responders; c) an expanded guidance for the selection and use of monitoring instruments including hand-held radionuclide identifiers, radiation portal monitors, backpack-type radiation detectors, mobile (terrestrial, maritime, aerial) systems, and active imaging systems; d) guidance for radiation monitoring at checkpoints; e) cyber assurance for monitoring instruments; and f) annexes detailing alarms and investigation levels, possible trafficked devices and radionuclides, and examples of naturally occurring radioactive material. Drafts of ISO 22188 were distributed to participating countries in two balloting stages (CD and DIS). WG 20 resolved all technical comments and prepared the final draft for balloting, with the target publish date of August 2023.

TPM-F.3   15:00  What’s New In International Nuclear and Radiation Protection Standards? JF Herrold*, University of Wyoming, US TAG Chair, ISO TC 85/SC 2

Abstract: The scope of International Organization for Standardization Technical Committee 85 (ISO/TC85) is “Nuclear energy, nuclear technologies, and radiological protection.” As of January 2023, there were 256 published ISO standards related to TC 85 and its subcommittees (SCs): 35 are under the direct responsibility of TC 85; 119 are under ISO/TC 85/SC 2 (Radiological protection); 83 are under ISO/TC 85/SC 5; and 19 are under ISO/TC 85/SC 6 (Reactor technology). Although all business in 2022 of ISO/TC 85, its SCs and working groups (WGs) was conducted through the internet, a lot was accomplished. Overall, 22 standards were published in 2022: 3 by TC 85; 12 by SC 2; 4 by SC 5 and 3 by SC 6. Work continues on 54 new and revised TC 85 standards. This presentation will give the audience a “taste” of the more noteworthy new and revised ISO/TC 85 standards. The author would like to thank the 75 dedicated experts (40 of whom are HPS members) who represent the US in ISO/TC 85 and SC working groups through the American National Standards Institute (ANSI) and the ISO/TC 85 Nuclear Technical Advisory Group (NTAG).

TPM-F.4   15:15  Pending Revision of ANSI N13.8-1973 Radiation Protection in Uranium Mines MD Hoover, Mark D Hoover LLC ; P Egidi*, US EPA; PH Jenkins, Bowser-Morner; JA Johnson, Sopris Environmental

Abstract: The scope and recommendations of ANSI N13.8-1973 Radiation Protection in Uranium Mines are being revised to reflect current radiation protection practices and mining realities. An adjustment of the title to Radiation Protection in Mining is proposed in recognition of the fact that exposures to radon and thoron decay products, and in some cases exposures to airborne radioactive dusts and whole-body exposures to external radiation, occur to some extent in all underground and surface mining operations, especially those involving extraction of rare earths and other minerals. It is noted that the 1973 standard treated limits on internal exposure and external exposure separately, which is inconsistent with current radiation protection approaches. The revised standard will recommend a graded approach to exposure-dependent and dose-dependent schedules for measurement and reporting of total exposure and dose to radon and thoron decay products, airborne radioactive dusts, and whole-body exposure to external radiation, as encountered in actual operations. Deference to requirements of applicable regulatory authorities is being recommended. The revised standard will also recommend the use of instrumentation that complies with the new IEEE/ANSI PN42.50 standard on Performance Specifications for Measuring Radon Progeny. New instrumentation capabilities for timely and efficient worker protection are now feasible because of the increasing availability of real-time methods for the sampling and monitoring of exposure to radon and thoron decay products. An informative annex will clarify issues of currently divergent exposure and dose limits, equivalencies, and regulations. Additional informative annexes will provide examples of radon and thoron decay product measurement methods, along with example reporting forms.
