Establishing historical 90 Sr activity in seawater of the China seas from 1963 to 2018

Historical Sr activity in seawater was established in the China seas from 1963 to 2018. Based on the exponential decrease in Sr activity in seawater, the effective half-life (EHL) of Sr was quantified to be 11.5 ± 1.6 a, 16.5 ± 2.4 a, 27.2 ± 6.2 a, and 26.7 ± 4.3 a in the Bohai Sea, Yellow Sea, East...

Zusammenfassung:	Historical Sr activity in seawater was established in the China seas from 1963 to 2018. Based on the exponential decrease in Sr activity in seawater, the effective half-life (EHL) of Sr was quantified to be 11.5 ± 1.6 a, 16.5 ± 2.4 a, 27.2 ± 6.2 a, and 26.7 ± 4.3 a in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea, respectively. We found contrasting patterns in the EHL of Sr and Cs in the marginal seas and open oceans that were closely related to the subtly different pathways of Sr and Cs in marine environment. Additionally, we demonstrated that Fukushima-derived Sr (
