What is the transport media of radiocaesium within river basin ?

Abstract

As already known, radiocaesium is transported with organic materials or onto small size particles such as clay minerals under the river flow condition. Thus, it is important to determine the relationship between mineral species and their radiocaesium concentration.

The results showed that the radiocaesium almost contained in sand fraction. We suggested the importance of radiocaesium quantity not only clay fraction but also sand fraction. In addition, mafic and felsic minerals in sand fraction could be contribute migration of radiocaesium as transport materials at river basin.
