“…This value is in the range of 1 200 Â 10 2 , which is the recommended distribution coefficient for cesium in sediments from IAEA (IAEA, 1985). The value is slightly higher than the level reported by Carroll et al (1999). They reported a range of 0:03 10 Â 10 2 in sediments from the Kara Sea.…”

“…Tagami and Uchida (2013) reported that the apparent K d values for seawater and coastal sediments are in the range of (0.035~1.5) ¥ 10 3 (geometric mean value, 2.0 ¥ 10 2 ) based on their summary of 194 previously published results. Other researchers have also reported K d values of about 10 2 (IAEA, 2004;Carroll et al, 1999;Nyffeler et al, 1984;RWMC, 1996).…”

rest of the released 137 Cs went out to the ocean. The radioactive aerosols were scavenged from the atmosphere to the ocean surface by dry and wet depositions, with the result that the deposition has increased the concentration of radio Cs in the surface seawater extensively (Aoyama et al., 2016; Kaeriyama, 2016; and references therein). Although radio Cs was in the uppermost surface layer and existed predominantly as dissolved species shortly after the FDNPP accident (e.g., Buesseler et al., 2012; Honda et al., 2012), it has since been realised that particles, with activity 4-5 orders of magnitude higher than that of the surface layer's suspended solids observed in their papers, had been scavenged/served to the sea bed with large sinking velocities (200-400 m/day) (Honda et al., 2013; Honda and Kawakami, 2014). In addition, suspended solids, which have small deposition rates and

“…There are many reports providing a range of K d s derived from field observations and laboratory experiments for each element. 11,[19][20][21][22][23][24][25] Assinder et al 26) reported a wide range of K d s based on in situ measurements at different tidal states in the Esk estuary. The variation of K d s for each element can occur as a result of a number of factors in estuarine water (e.g., riverine and benthic element input and complexation of an element with dissolved organic matter or resuspended particulate matter) 1,25) or sediments (e.g., interaction with organic matter and/or Fe hydroxides).…”

Sediment-water distribution coefficients (K d s) were obtained in estuarine areas of four A-class rivers in Japan. The total concentrations of stable elements and naturally occurring radionuclide (i.e., Na, Mg, K, Ca, V, Mn, Fe, Co, Ni, Cu, Rb, Sr, Y, Mo, Cd, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Pb, and U) in the estuarine water at each sampling point and in the corresponding sediment sample were measured. K d s of most of the elements varied within one order of magnitude regarding their differences between minimum and maximum values of each element at all the stations. However, a wide variation of K d s of Mn, Fe, Co, Cu, Rb, and La was observed. In addition, geometric means (GMs) of observed K d s were compared with the recommended values in the IAEA Technical Report Series 422 (TRS-422). The results showed that GMs of K d s for most of the elements agreed well with the recommended values, but GMs of K d s for Mn, Fe, and Cd were more than 10 times lower than the recommended values. The obtained K d values could be important to investigate the behavior, transport, and fate of artificial radionuclide and to assess the radiological doses in estuarine areas.
