Concentrations of 137Cs, 90Sr, 108mAg, 239+240Pu and atom ratio of 240Pu/239Pu in tanner crabs, Chionoecetes japonicus and Chionoecetes opilio collected around Japan

Distribution of ¹³⁷Cs Radionuclide in Industrial Wastes Effluents of Gresik, East Java, Indonesia

“…All of the produced industrial wastes flow through the river which flows to the Java Sea. Janssen et al [16] and Morita et al [17] found that 137 Cs will accumulate in soil, plants and marine organisms and are affected by competing ions such as potassium, calcium, ammonium, and other inorganic minerals such as other monovalent cations [18]. In order to determine the sources and present levels of 137 Cs in the coastal waters of Gresik, hydrological factors which affect the nuclide's distribution process in the water column, such as currents, salinity, and pH, were determined.…”

Artificial and natural radionuclides in cryoconite as tracers of supraglacial dynamics: Insights from the Morteratsch glacier (Swiss Alps)

“…The identification of 108m Ag is an important finding, since this artificial radioactive nuclide (t 1/2 418 yr) has never been reported in terrestrial environments. It has only been occasionally observed in tissues of marine organisms where silver is bio-accumulated (Morita, et al, 2010), in marine sediments collected at nuclear testing sites in the Pacific (Beasley & Held, 1971), and during the evaluation of material radiopurity for rare event physics experiments (Laubenstein, 2017).…”
