Retention of 2011 Fukushima Dai-ichi NPP accident-derived 137Cs in the northern North Pacific–Bering Sea [PDF]
Scientific ReportsTracing soluble radionuclides is critical for understanding the mechanisms underlying the transport of soluble materials in marine environments. In the present study, we investigated the surface distribution of the concentrations (activities) of 134Cs ...

Fractionation of 226Ra and Ba in the Upper North Pacific Ocean
Frontiers in Marine Science, 2022 Investigations conducted during the GEOSECS program concluded that radium-226 (T1/2 = 1602 y) and barium are tightly correlated in waters above 2500 m in the Atlantic, Pacific and Antarctic Oceans, with a fairly uniform 226Ra/Ba ratio of 2.3 ± 0.2 dpm ...

Radioactivity of soil in Croatia I: naturally occurring decay chains
Arhiv za Higijenu Rada i Toksikologiju, 2021 The assessment of environmental radioactivity much relies on radionuclide content in soil. This stems from the significant contribution of soil to both external and internal exposure to ionising radiation via direct emission of gamma radiation and soil ...

An Efficient Radiochemical Method for Extraction of 226Ra From the Soil Samples [PDF]
Avicenna Journal of Medical Biochemistry, 2019 Background: Radium-226 is a radioactive element, with a very long half-life of 1600 years, producing radon gas. According to the United States Environmental Protection Agency, radon gas is the second most important factor causing lung cancer. Objectives:
