The migrations of Sr/sup 90/ in natural soil were observed for three years by using 3-mc Sr/sup 90/ solutions placed at 2-cm and 5-cm depths in a 1.5x 1.5 m area covered with grass. The content of Sr/sup 90/ was measured in plants and soil at concentric peripheries of 0 to 5, 5to 10, 10 to 15, 15 to 20, 20to 25, 25to 35, and 35to 45 cm and in a 70-cin soil cross section taken vertically and horizontally every 5 to 10 cm. The results show a limited Sr/sup 90/ migration from The content of Sr/sup 90/ was measured in plants and soil at conceniric peripheries of 0 to 3, 5 to 10, 10 to 15, 15 to 20, 20to 25, 25to 35, and 35to 45 cm and in a 70-cin soil cross section taken vertically and horizontally every 5 to 10 cm. The results show a limited Sr/sup 90/ migration from the initial spot. Moreover, the horizontal migration was twice the vertical. The faster horizontal migration is the result of transmission through the roots of plants. (R.V.J.)
