Results and Discussion: According to the result of the environmental radioactivity verification surveillance in the vicinity of nuclear power facilities in 2017, the anthropogenic radionuclides were not detected in most of the environmental samples except for the detection of a trace level of 137Cs, 90Sr, Pu, and 131I in some samples. Radioactivity concentration ratios between the anthropogenic radionuclides (137Cs/90Sr, 137Cs/239+240Pu, 90Sr/239+240Pu) were similar to those reported in the environmental samples, which were affected by the global fallout of the past nuclear weapon test, and Pu atomic ratios (240Pu/239Pu) in the terrestrial sample and marine sample showed significant differences due to the different input pathway and the Pu source. Radioactive iodine (131I) was detected at the range of < 5.6–190 mBq∙ kg-fresh–1 in the gulfweed and sea trumpet collected from the area of Kori and Wolsong intake and discharge. A high level of 3H was observed in the air (Sangbong: 0.688±0.841 Bq∙ m–3) and the precipitation (Meteorology Post: 199±126 Bq∙ L–1) samples of the Wolsong nuclear power plant (NPP). 3H concentration in the precipitation and pine needle samples showed typical variation pattern with the distance and the wind direction from the stack due to the gaseous release of 3H in Wolsong NPP.

The contributions of nuclear science and technology in enhancing prosperity and quality of life all over the world and its potential to achieve many important Sustainable Developments Goals (SDGs) of the United Nations are well recognized. It also is now recognized that with fewer students getting attracted to Science, Technology, Engineering and Mathematics (STEM) in general and nuclear science and technology (NST) in particular; hence, there is a vital need to reach out to young students to provide the crucial human resources needed for these endeavours to continue in this highly specialized area. The success of a recently completed IAEA project related to introducing NST during 2012–2016 in secondary schools in the Asia-Pacific region countries encouraged the formulation of a new IAEA TC project RAS0079 entitled “Educating Secondary Students and Science Teachers on Nuclear Science and Technology” for 2018– 2021, focusing on enhancing existing educational approaches through training and development opportunities both for teachers and students. The project aims at reaching a million students during the project duration while keeping the depth of learning between teacher and student. The strategy of executing the project, implementation status and its impact so far is presented in this paper.

The editorial committee of the Journal of Radiation Protection and Research (JRPR) is pleased to announce that, starting from this issue (September 2019), the JRPR is copublished by three societies — the Korean Association for Radiation Protection (KARP), the Japan Health Physics Society (JHPS), and the Australasian Radiation Protection Society (ARPS) — as the official journal of the three societies. Recently, KARP’s president, Prof. Woo-Yoon Park, proposed to make the JRPR, which had been KARP’s journal for more than 30 years, an international journal. Then, at the 5th Asian and Oceanic Congress on Radiation Protection (AOCRP-5) held in Melbourne, Australia in 2018, the presidents of the three societies agreed to adopt the JRPR as their joint, co-published journal. Since then, the editorial committee, the journal homepage, and all related documents have been revised to reflect the change. JRPR’s Editorial Committee now comprises three Editors-in-Chief representing the three societies, respectively, twelve Editors from the three societies (4 each), fifteen International Editors from foreign societies, and a Managing Editor in Korea who will run the JRPR on a daily basis. The JRPR, in order to broaden its global scope, will try to appoint International Editors from at least 12 foreign societies. The purpose of the JRPR is to disseminate scientific and technical information on radiation protection and related issues, covering both ionizing and non-ionizing radiations. The topics cover radiation physics and detection, radiation dosimetry, dose monitoring and evaluation, radiation biology and epidemiology, radiation risk assessment, radiation public health and environmental impacts, radiation safety and regulations, training and education, and social science and participation including social communication and risk communication. The new co-published JRPR is an open-access journal that is published four times a year (March 31, June 30, September 30, and December 31). The official language of the journal is English. The new JRPR is the output of a great amount of work in a relatively short time. The efforts of several members of the Editorial Committee are truly appreciated. Especially, the previous Managing Editor, Prof. Chul Hee Min, and the current Managing Editor, Prof. Geehyun Kim, are thanked for understanding the importance of a co-published international journal and for their time and effort in helping to realize it. Special thanks also go to Dr. Moon Hee Han, the previous Editor-in-Chief, both for his long service with the former JRPR and for his time and effort in helping to establish the new journal. It is believed that the new co-published JRPR, along with the well-established Asian and Oceanic Congress on Radiation Protection (AOCRP), will significantly enhance the exchange of scientific knowledge and experience in radiation protection among researchers in Asia, Oceania, and the entire world.

Materials and Methods: We examined data from brain embolization (n = 30), hepatic chemoembolization (n = 50), and uterine embolization (n = 12). The PSDs were measured using radiochromic film around the patient’s head (group 1) or abdominal/pelvic region (group 2). Acquisition technical data and kerma-area products (KAP) were also recorded. Occupational doses were measured using InstadoseTM dosimeters near the left eye region (LER), chest, and left ankle.

Background: Dose rate meters are the most widely used, and perhaps one of the most important tools for the measurement of ionising radiation. They are often the first, or only, device available to a user for an instant check of radiation dose at a certain location. Throughout the world, radiation safety practices rely strongly on the output of these dose rate meters. But how well do we know the quality of their output?

Materials and Methods: The existing X-ray generator, Phillips MG325, was replaced with YXLON Y.TU 320-D03 in order to generate reference X-ray fields. Theoretical calculations and Monte Carlo simulations were used to determine initial filter thickness. Beam alignment was performed in three steps to deliver a homogeneous radiation dosage to the target at different distances. Finally, the half-value layers were measured for different X-ray fields to verify beam qualities by using an ion chamber.

Background: As neutron fields are always accompanied by gamma rays, it is essential to distinguish neutrons from gamma rays in the detection of neutrons. Neutrons and gamma rays can be separated by pulse shape discrimination (PSD) methods. Recently, we performed characterization of a stilbene scintillator detector and an EJ-301 liquid scintillator detector with a highspeed digitizer DT5730 and investigated optimized PSD variables for both detectors. This study is for providing a basis for developing fast neutron/gamma-ray dual-particle imager.

Materials and Methods: Count rate data sets in time series were collected from 9 monitoring posts. All of the count rate data were measured every 15 minutes from the region of interest (ROI) for 137Cs (Eγ = 661.6 keV) on the gamma-ray energy spectrum. The Shewhart (3σ), CUSUM, and Bayesian S-R control chart methods were evaluated and the comparative analysis of determination methods for count rate data was carried out in terms of the false positive incidence rate. All statistical algorithms were developed using R Programming by the authors.

Background: To monitor proton beam in proton therapy, prompt gamma imaging systems are being developed by several research groups, and these systems are expected to improve the quality of the treatment and the patient safety. To apply the prompt gamma imaging systems into spot scanning proton therapy, the systems should be able to monitor the proton beam range of a spot with a small number of protons ( <108 protons), which is quite often not the case due to insufficient prompt gamma statistics.
