The FNCA 2024 Workshop on Radiation Safety and Radioactive Waste Management (RS&RWM) project was held in a hybrid form in Serpong, Indonesia, October 22 - 24, 2024. The workshop was hosted by National Research and Innovation Agency (BRIN) and the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan.
Representatives from 11 FNCA member countries (Australia, Bangladesh, China, Indonesia, Japan, Kazakhstan, Malaysia, Mongolia, Philippines, Thailand and Vietnam) participated in the workshop.

[Workshop]

In the opening session, welcome remarks were delivered by Dr. Maman Kartaman Ajiriyanto, Head of Research Center for Nuclear Material and Radioactive Waste Technology, BRIN, and Mr. Totti Tjiptosumirat, FNCA Coordinator of Indonesia. Following the welcoming remarks, Mr. WADA Tomoaki, FNCA Advisor of Japan, expressed opening remarks.
In the new phase from FY2024 to FY2026, activities will focus on environmental radiation and radioactivity around nuclear facilities. Participants will collect and review information on government policies and systems, current status and problems in member countries, with the aim of compiling an integrated report in FY2026, the third year of the phase.
Participants from each country reported national radiation protection policies and topics related to environmental radiation and radioactivity.

In the group session, the participants were divided into two groups to discuss the issues to be addressed, the table of contents, and other things deemed necessary for the preparation of the integrated report and to deepen mutual understanding. The poster session featured presentations from Australia, Indonesia, Japan, Mongolia, the Philippines, and Thailand on current issues in their countries.
The workshop was closed with the closing remarks Dr. Maman Kartaman Ajiriyanto, project leader of Indonesia, and Prof. KOSAKO.

[FNCA Open Seminar]

In the morning of the second day (Oct. 23), the Open Seminar was held at the BRIN. Approximately 60 participants from BRIN and government agencies participated in the open seminar in a hybrid form. Those participants from Australia, China, Japan, and Indonesia gave presentations on their decontamination activities at radioactive waste facilities and other sites and lively exchanged their views.

[Technical Visit]

In the afternoon of the second day (Oct. 23), a technical visit to the Radiation Data Monitoring System (I-RDMS) facilities in Indonesia Center of Excellence on Nuclear Security and Emergency Preparedness (I-CoNSEP) at the BAPETEN was conducted.

The Workshop was attended by 27 participants in person and online from 11 FNCA member countries, namely Australia, Bangladesh, China, Indonesia, Japan, Kazakhstan, Malaysia, Mongolia, the Philippines, Thailand and Vietnam, including workshop staffs. The program of the workshop is attached as Annex 1. The list of participants is attached as Annex 2.

Session 1: Opening

At the beginning of the workshop, Dr. Maman Kartaman Ajiriyanto, Head of Research Center for Nuclear Material and Radioactive Waste Technology, BRIN, and Mr. Totti Tjiptosumirat, FNCA Coordinator of Indonesia, delivered welcoming remarks. Following the welcoming remarks, Mr. WADA Tomoaki, FNCA Advisor of Japan expressed opening remarks.

Session 2: Introduction

Mr. WADA gave a presentation on achievements and activities of the FNCA projects. Prof. KOSAKO Toshiso, Project Leader of Japan, presented on overview and goal of current phase of the RSRWM project. The prerequisite understanding of this phase starting in 2024 is based on “Radiation related facilities ultimately release radioactive materials into the natural world”. After three years discussions, the products will be summarized in 2026 as a consolidated report. The summary of each report is attached in Annex 3.

Session 3: Country Report

The member countries reported national radiation protection policies and topics related to environmental radiation and radioactivity. The summary of each report is attached in Annex 3.

Session 4: Wrap-up of Day 1

Prof. KOSAKO mentioned that we found a lot of important points of the environmental radiation and radioactivity through presentation and discussion today and will continue our work tomorrow.

Session 5: Presentation on environmental radiation and radioactivity

First presentation was delivered by Dr. Mohd Zaidi Bin Ibrahim regarding environmental radiation and radioactivity in radiation related facilities in Malaysia. Prof. KOSAKO made a presentation on environmental radioactivity monitoring in Japan Chemical Analysis Center (JCAC), which have been continued the efforts to improve the reliability of environmental radioactivity monitoring. Mr. Duncan kemp explained the environmental monitoring approach in detail for ANSTO, along with the general principles of source, pathway and receptor. The focus was on the airborne emissions and the liquid emissions from the site. The summary of the report is attached in Annex 3.

Session6&7: Group Discussion on Consolidated Report

The participants discussed environmental radiation and radioactivity.

Session 8: Poster Session

Six countries introduced their hot topics using a poster. The title of each poster is as shown below:

• Australia: Modelling the Airbourne Emissions from a Nuclear Facility
• Indonesia: Remediation project of 137Cs-contaminated soil
• Japan: Outline of Public Exposure and NORM Management in Japan
• Mongolia: Environmental radioactivity in Mongolia
• Philippines: Airborne Radiation: Monitoring Radon Inside a Radioactive Waste Management Facility
• Thailand: Utilization of bentonite in cementation of electric arc furnace dust contaminated with ¹³⁷Cs

The summary of each poster is attached in Annex 3.

Session 9: Summary

This summary was adopted by the participants.

Session 10: Closing

The workshop was closed with the closing remarks from Dr. Maman Kartaman Ajiriyanto and Prof. KOSAKO.

[FNCA Open Seminar]

The Open Seminar was held at the BRIN on the second day morning (October 23). The seminar was attended by 62 people in person and online from BRIN and government organization. Following the welcoming speech by Prof. Kosako, there were 4 presentations on the themes of 1) FNCA activities in MEXT, 2) Australian Facility Decontamination, 3) New technologies and applications for waste treatment and decontamination, and 4) Decontamination Program of Radioisotope and Radiopharmaceutical Production Installation.

[Technical Visit]
