“…A group of researchers demonstrated that the current traveled from Japan to the California coast by monitoring the ocean's surface, which aggravated the negative impact brought by the disposed nuclear wastewater [2]. Similar statements have also been proved by other researchers claiming that within two years of the Fukushima Nuclear disaster, manufactured radioactive isotopes from FDNPS had reached the western Pacific Ocean edge and the west coast of North America [3]. In addition to the nuclear pollutant that can be spread by the ocean current, there were also isotopes such as 14C, 137Cs, and 134Cs that quickly accumulate on the seabed and in marine organisms close to Japan do not disperse with ocean currents and pose a long-term threat to the region's marine ecosystem [4].…”

With the increasing use of nuclear energy, human lives have benefited from a variety of aspects since nuclear energy can produce carbon-free electricity. Nevertheless, governments must be cautious about the waste nuclear energy produces for it’s extremely harmful to the environment and has detrimental impacts on human health. Since the nuclear water at the Fukushima plant was released in the following years after 2011, both Japan and its neighboring countries were seriously affected. Some other coastal areas also have varying degrees of pollution depending on the ocean current. The extent of the impact of nuclear wastewater namely the affected areas and the diffusion of elements in nuclear wastewater will be shown in the paper. Additionally, this paper will analyze and elaborate on how nuclear wastewater can affect the marine environment due to the structure of the marine environment and the properties of nuclear wastewater. Lastly, the impact of nuclear wastewater on the fishery in Japan and neighboring countries will be discussed by showing data from relevant research papers. This paper will focus on the impact of nuclear wastewater on the marine environment and the vicinity fishing industry.

“…Conversely, to anticipate the possible entry of radionuclide contaminants from nuclear disasters in Indonesian waters such as fukushima in 2011, the national radioactive marine monitoring program using 137cs was used to determine several marine biota species. This includes deep-sea monitoring off the west coast of the Sumatra-Indian ocean (17,18).…”

historis, BATAN didirikan untuk mengantisipasi dampak negatif akibat percobaan ledakan nuklir di wilayah Pasifik di masa lalu. Saat ini, satu Pusat dari lembaga pemerintah ini memiliki tugas untuk melakukan penelitian dan pengembangan serta layanan di bidang keselamatan dan metrologi radiasi. Tujuan dari makalah ini adalah membahas semua kegiatan yang dilakukan oleh Pusat ini yang mencakup banyak aspek dalam pengkajian keselamatan pekerja, masyarakat dan lingkungan. Untuk metrologi radiasi, sumber standar laboratorium dosimetri (SSDL) dalam layanan kalibrasi dibangun untuk mendukung keberhasilan dalam radioterapi, di mana pencapaian tertinggi adalah sebagai Lembaga yang Ditunjuk untuk Radiasi Pengion. Penelitian kesehatan mencakup pemanfaatan sinar gamma untuk mengembangkan bahan vaksin, diagnosis penyakit metabolik dengan teknik kedokteran nuklir dan mikrodosimetri dalam penilaian radiodiagnostik. Untuk radioekologi dan biologi radiasi, salah satu penelitian utama adalah penentuan dosis efektif dan studi epidemiologi di Mamuju sebagai daerah radiasi latar belakang tinggi (HBRA) yang memberikan kesempatan unik untuk mempelajari efek kesehatan dari paparan radiasi kronis tingkat rendah pada manusia. Melalui kerja sama dengan Universitas Hirosaki, penting untuk menilai kesehatan dan status fisik serta kerusakan asam sitogenetik dan deoksinukleotida (DNA) dalam limfosit populasi lokal yang dapat memberikan informasi yang berharga. Studi dosimetri dilakukan dengan pengukuran langsung di area lapangan, termasuk analisis paparan radiasi eksternal dari tingkat dosis gamma di dalam dan di luar ruangan. Penentuan radiasi internal dilakukan dengan mengambil sampel makanan, urin, air minum, dan air inhalasi (radon). Studi epidemiologis melalui respon sitogenetik dari tempat tinggal yang didukung oleh γ-H2AX, G0 dan G2 micronucleus, dan genotip TP53 dari daerah penelitian menunjukkan bahwa tidak ada perbedaan yang signifikan dalam efek radiasi alami dengan kontrol. Studi radiologi kelautan dan pemantauan radionuklida di seluruh kepulauan Indonesia juga tidak menunjukkan suatu dampak negatif. Praktik kedaruratan nuklir pun juga harus dilakukan secara rutin di Pusat ini untuk memperkuat budaya keselamatan dan keamanan.

“…The released radionuclides would spread rapidly along with ocean currents, causing widespread impact. It is reported that the artificial radioactive isotopes from FDNPP have arrived western margin of the Pacific Ocean and west coast of North America within 2 years after the Fukushima Nuclear Accident (Smith et al , 2015; Suseno and Wahono, 2018).…”

PurposeJapan's decision to release nuclear wastewater into the Pacific Ocean in 2023 has sparked strong opposition at home and abroad. In this study, Graph Model for Conflict Resolution (GMCR) method is adopted to analyze the conflict problem, and reasonable equilibrium solutions are given to solve the conflict event.Design/methodology/approachIn this study, GMCR is adopted to solve the conflict problem. First, identify the key decision-makers (DMs) on the issue of nuclear effluent and the relevant options they might adopt. Second, the options of each DM are arranged and combined to form a set of feasible states. Thirdly, the graph model is constructed according to the change of DM's options, and the relative preference of each DM is determined. Finally, the conflict problem is solved according to the definition of GMCR equilibrium.FindingsDischarging nuclear wastewater into the ocean is not the right choice to solve the problem. Developing more space to store nuclear wastewater is more conducive to the protection of the ocean environment.Practical implicationsIt is undesirable for the Japanese government to unilaterally discharge nuclear wastewater into the ocean. Objectively assessing the radioactivity of nuclear wastewater and the cooperation of relevant stakeholders can better solve this conflict.Originality/valueThe problem arising from Japan's releasing plan is complicated because of a lack of information and the existence of multiple stakeholders, while GMCR can help us with a better view of the current circumstance in the conflict.
