The accumulative dynamic of 89Sr in the kidney bean and its effect on the waters were studied. It is shown that 89Sr would tyansfer to kidney beau rapidly and the accumulation of 89Sr in the kidney beau follows a positive exponential relation with time

but follows a negative exponentical relation with depth of the soil. After the soil was leached and seeped by rain

the 89Sr would enter into waters for 5% and be distributed to each component of waters. The specific activity of 89Sr was low in the waters and honewort

high in the bottom mud

and highest in the fish and snail

showing that fish and snail can strongly concentrate 89Sr in waters.
