Abstract : Methods for evaluating the significance of fallout ingress into shelters through broken windows are examined. A limited small-scale experimental simulation was performed to test the sensitivity of ingress-loading ratios to such variables as number of windows, window area, wind speed, and wind direction. In addition, a geometric method for estimating fallout ingress is described. The significance of fallout ingress in terms of increasing exposure of shelter occupants to ionizing radiation is assessed, both on a local and on a national scale. (Author)
