Abstract : Particulate penetration into the USNRDL experimental shelter via the ventilation system operating without filters was determined as a function of particle size. Relatively good agreement was found with the small amount of applicable Shot Small Boy data. Estimates of the dose within a shelter due to particulate penetration and deposit (ingress dose) were made using values of fallout model parameters for weapon yields of 100 to 100,000 KT (assuming 100% fission). Ingress doses are presented as a function of particle size and downwind distance so that the particle sizes of importance may be determined for any given acceptable ingress dose.
