DNA 1240H-2 Hordtack resulting from combustion air intakes were within the dose range estimated theoretically.°? It should be noted that accurate estimates of ingress dose are still impossible. References 33 and 66 represent the best available information, but even in these studies, results could be presented only as a wide range of values due to uncertainties, assumptions, and approximations in the ingrese-dose estimates. For underwater bursts at shallow or moderate depths, such as Shots Umbrella and Wahoo, comparison of estimated ingress doses with total doses at below-decks locations reveals that the doses due to ingress of contaminant were in all cases secondary to the doses due to transit radiation. However, if shielding were provided to reduce the dose due to exterior transit radiation, then radiation due to interior contamination from bursts such as these two could require consideration. For deep underwater bursts, such as Wigwam, there was no detectable contamination of ships traversing the path of the aerosol within 20 min after burat. VW7-112 See
