Abstract

The aim of this experiment was to evaluate to what degree bentonite was able to suppress cesium (Cs)-transfer to the organs. Six healthy Holstein-Friesian calves were administered cesium chloride (CsCl), a compound of a stable isotopic Cs, with powdered milk solution for 28 days (3.0mg CsCl/kg/day). At the same time, three of the six calves were also given bentonite (0.5w/v %); the other three were used as controls. Blood samples were taken on days 0, 1, 2, 3, 7, 14, 21, and 28 of the experiment, and tissues were collected from the skeletal muscle, heart, liver, kidney, and feces on day 28. The concentrations of Cs in the samples were measured by ICP-MS (inductively coupled plasma mass spectronomy). The average Cs concentration in blood corpuscles from the bentonate group was lower than that of the control group until day 14, although the concentrations in the tissues of the above organs were not clear. This suggests that bentonite may reduce Cs-transfer to the living body.
